Sequence pneumonia in anthrax: pneumonia = 484.5, anthrax = 022.1.
1.) False. A diagnosis that mentions the affected lobe is not classified as lobar pneumonia unless specifically documented by the physician.
2.) False. “Multilobar pneumonia” simply refers to pneumonia affecting more than one lobe.
1.) True/False? A diagnosis of pneumonia that mentions the affected lobe is classified as lobar pneumonia.
2.) True/False? “Mutilobar pneumonia” is synonymous with lobar pneumonia.
The code for AIDS (042) is always sequenced first.
For example:
042 (AIDS) + 136.3 (Pneumocystosis)
What is the correct coding for Pneumocystosis (136.3) associated with AIDS?
Both types of pneumonia must be coded therefore two codes would be assigned.
What is the appropriate coding when the diagnostic report indicates that a patient has both aspiration pneumonia as well as another type of pneumonia such as bacterial?
Code influenza (487.0) with an additional code assigned to identify the type of pneumonia.
How should influenza (487.0) with pneumonia be coded?
True. These subcategories represent another exception to the general guidelines that direct the coder to assign a code diagnosis qualiified as “suspected” or “possible” as if it were established.
True/False? Subcategories 488.0, 488.1, and 488.8 indicating cases of avian flu, identified (novel) 2009 H1N1 flu, or novel influenza A should not be assigned when the diagnostic statement indicates when the infection is “suspected”, “possible”, “likely”, or “?”.
1. Chronic obstructive asthma (493.2x)
2. Chronic obstructive bronchitis (491.2x).
3. Emphysema (492.8).
4. Chronic bronchitis with emphysema (491.20).

True. The described conditions are synonymous and code to 491.21, obstructive chronic bronchitis, with acute exacerbation.
True/False? COPD in exacerbation, severe COPD in exacerbation, end stage COPD in exacerbation, decompensated COPD, exacerbation of COPD, and acute exacerbation of chronic obstructive bronchitis all code to the same thing.
Code 496 – find under: “obstruction”, “airway”, “chronic”.
When the medical record documentation indicates COPD without further specification, the correct code can be found under ______?
Two codes are required:
1. 491.2x (Chronic obstructive bronchitis)
2. 493.22 (Chronic obstructive asthma with acute exacerbation).
An overlapping condition of chronic obstructive asthma with an acute exacerbation with chronic obstructive bronchitis (COPD) should be coded with ________?
False. The code description for 491.22 obstructive chronic bronchitis contains acute bronchitis in its description. No additional code is necessary. Only assign 491.22.
True/False? A diagnosis of acute bronchitis with obstructive chronic bronchitis requires a code for the COPD (491.22) with an additional code for the acute bronchitis (466.0).
No. The acute bronchitis included in 491.22 supersedes the acute exacerbation.

When can acute respiratory failure be assigned as the principle diagnosis?
1.) Principal diagnoses = 518.81 (acute respiratory failure) + 492.8 (other emphysema).
2.) Principal diagnoses = 518.81 (acute respiratory failure) + 358.01 (Myasthenia gravis with acute exacerbation).
In both cases the acute respiratory failure is sequenced first because it is the reason for admission.
Sequence the following:
1.) A patient with emphysema (492.8) who develops acute respiratory failure (518.81). The patient is admitted through the emergency department for treatment of the respiratory failure.
2.) The patient with chronic Myasthenia gravis goes into acute exacerbation (358.01) and develops respiratory failure (518.81). The patient is admitted due to respiratory failure.
Principal diagnoses = 042 (AIDS) +
518.81 (acute respiratory failure) +
136.3 (pneumocystosis).
042 (AIDS) is sequenced first because of a chapter specific guideline that instruct the coder to assign 042 as the principle diagnoses. Always follow ICD-9 guidelines and instructional notes.
Sequence the following:
A patient is admitted to respiratory failure due to pneumocystis carinii, which is due to AIDS.
Principal diagnoses = 031.11 (Staphylococcus aureus septisemia) +
995.92 (severe sepsis) +
518.81 (acute respiratory failure).
The septisemia is sequenced first in this case because of chapter specific instructional notes to first code the underlining infection. Always follow ICD-9 guidelines and instructional notes.
Sequence the following:
A patient is admitted to the hospital with severe Staphylococcus aureus sepsis and acute respiratory failure.
1.) Code for ARDS is assigned + an additional code for the responsible organism.

Assigned 519.01 as a complication and add an additional codes to identify the type of infection and the organism.
How is infection of a tracheostomy (519.01) assigned?
Only assign 557.0 (acute vascular insufficiency of intestine). 578.x to indicate GI bleeding is not used when a code for a specific condition such as ischemic colitis include hemorrhage or GI bleeding.
When a physician lists “GI bleeding (578.x) due to ischemic colitis (557.0)” and “hemorrhagic” is an inclusion term under code 557.0 how should this be coded?
Yes. If the physician documents a clinical diagnosis of GI bleeding the fact that no bleeding occurs during the episode of care does not preclude the assignment of a code that includes a mention of hemorrhage, or a code from category 578 when the cause of the bleeding can not be determined.
For patient with a documented diagnosis of GI bleeding should the GI bleeding still be coded if the patient is no longer bleeding at the time of the examination?
Only code the Mallory Weiss Tear.

It is the coding clarification source for all coders.
Outpatient:
Question:
What should Coders do if they come across a complex ICD-9 coding issue while coding radiology reports that they are not sure how to code something?
V22.0, supervision of normal first pregnancy
V22.1, supervision of other normal pregnancy(For complications of pregnancy, the above codes are not reported with codes 630-679)
Outpatient:
Routine Outpatient Prenatal Visits
This guideline for prenatal visits applies when the prenatal visit occurs and the patient has no current complications.
Under these circumstances, the first-listed diagnosis is reported as either:
– The current or primary cancer site should be coded.
-If the patient is no longer being treated for cancer and it is clearly documented that the patient no longer has cancer, only the history of cancer should be coded
-Use the observation and evaluation codes (V71.X) when no other indication is listed e.g.
Assign code V71.1, for observation for suspected malignant neoplasm, as the primary dx for PET scans, when the scan is being done to determine “potential” spread of a malignancy
Outpatient:
Diagnostic Radiology Coding Outpatient Coding Challenges:
Another confusing situation is when “rule-out metastasis” is ordered.
Code original cancer site along with any findings
If there are no findings, only the original cancer site should be coded
Outpatient:
Example3:
Indication for test: Rule-out metastasis
Findings: Normal x-ray
What to Code:
If there is a good symptom provided, only that symptom is coded. V71 should not be added as a secondary code
If no signs or symptoms are documented, then the V71.xx code is appropriate
Outpatient:
Diagnostic Radiology Coding Outpatient Coding Challenges:
Common Rule-Out Challenges
Example1: Indication for test: Rule-out pneumonia
Findings: Normal chest x-ray
Coded as?
If there is a good symptom provided, only that symptom is coded. V71 should not be added as a secondary code. If no documentation of signs or symptoms, then assign the V71.xx code
Note: This is same as the previous screen’s example with “normal” findings on the radiology reports
Outpatient:
Diagnostic Radiology Coding Outpatient Coding Challenges:
Example2:
Indication for test: Rule-out appendicitis
Findings: Normal abdominal x-ray
What to Code?
A common follow-up exam is for fracture aftercare
For follow-up of a fracture, coders can use V54.X (other orthopedic aftercare) as the primary diagnosis
Outpatient:
Also, many coders are faced with rule-out diagnosis when the patient is receiving follow-up or aftercare
Code V54.x (other orthopedic aftercare)
Outpatient:
Example4:
Indication for test: Follow-up fracture
Findings: Normal x-ray
What to Code:
“Trauma” alone cannot be coded as an injury and should instead assigned as V71.4 (observation following other accident)
Answer: Trauma is not always indicative of injury. If there are no findings after diagnostic testing, assign code V71.4, Observation following other accident. However, the patient presents with symptoms (i.e., pain, swelling, tenderness, etc.) assign the appropriate code for the symptoms.
Outpatient:
What is coded if the reason for the radiology service is specified only as “trauma”? e.g. CT scan following trauma:Question: CT scan ordered for treatment of injuries sustained for patient following an accident. Reason for the CT is documented on report as “trauma”. How should this be coded?
These are probable or suspected conditions that cannot be coded in the outpatient setting. Coders should code to the highest degree of certainty for the particular encounter, using indicators such as signs or symptoms or other positive findings in the medical report (Vol. 22, No. 3, third quarter, 2005)
Outpatient:
How should unconfirmed diagnoses described in terms such as “consistent with,” “compatible with,” “indicative of,” “suggestive of,” and “comparable with” be coded in the outpatient setting?
Code that diagnosis. The signs and/or symptoms that prompted ordering the test may be reported as additional diagnoses if they are not fully explained or related to the confirmed diagnosis
Outpatient:
Diagnostic Test Ordered Due to Signs and/or Symptoms
If the physician has confirmed a diagnosis based on the results of the diagnostic test, the coder should ___________?
Dx code: diverticulitis 562.11
The abdominal pain would not be coded as it is a symptom of the diverticulitis.
Outpatient:
Example: A patient is referred to a radiologist for an abdominal CT scan with a diagnosis of abdominal pain. The CT scan reveals numerous diverticula in the cecum and descending colon. The Impression on the CT report states a diagnosis of “diverticulitis with no evidence of diverticular abscess.
The sign(s) or symptom(s) that prompted the treating physician to order the study should be coded.
The radiologist should report a diagnosis of “knee pain” since this was the reason for performing the X-ray – Dx Code: 719.46 knee pain
Outpatient:
What should be coded if the diagnostic test did not provide a diagnosis or was normal? Example: A patient is referred to a radiologist for a X-ray due to complaints of “knee pain”. The radiologist performs the x-ray, and the results are normal.
Do not code that diagnosis but instead, report the sign or symptom/s that prompted the study.
Outpatient:
How should the results of diagnostic test are normal or non-diagnostic be coded when the referring physician records a diagnosis preceded by words that indicate uncertainty such as probable, suspected, questionable, rule out, or working?
Incidental findings would not be coded. Refer back to the reason for the test at the top of the radiology report or the physician order. The reason for the testing would be the primary diagnosis.
Outpatient:
If the Impression or Conclusion of the radiology report is an incidental finding and the radiologist states “incidental” then how would this be coded?
The reason for the test should be coded, such as if it was a screening or what kind of testing it is being performed. If there are findings, then those would be coded as additional diagnoses
Dx Code: V76.12 for the screening and 793.89 for the breast calcification.
Outpatient:
Diagnostic Tests Ordered in the Absence of Signs and/or Symptoms (e. g. screening tests)
When a diagnostic test is ordered in the absence of signs/symptoms or other evidence of illness or injury and therefore no diagnosis documented on the order, Example: Asymptomatic patient coming in for a Screening mammogram, The mammogram Impression states breast calcifications are found.
How should this be coded?
Look closely at the order to see if this is an order for a Screening Mammogram or a Diagnostic Mammogram.Orders for Screening Mammograms will be documented as “Screening” or it will be checked marked off as Screening. Orders for Diagnostic Mammograms will be documented as “Diagnostic and there will usually be a dx on that order for the reason for the test. Mammograms will be identified as either Screening or Diagnostic at the top of the report- be sure to look for this.
Outpatient:
Mammograms:
Screening Mammograms
Codes V76.12, V76.11
Diagnostic Mammograms
An ICD-9 code that describes the patient’s documented signs or symptoms such as a lump, pain, thickening, a change in size or shape of the breast
Answer:
Assign code V76.12, Special screening for malignant neoplasm for this encounter
Outpatient:
Screening Mammogram:
Coding Clinic, Second Quarter 2003
Question:
A healthy 40-year-old woman presents to the radiology department for a screening mammogram. The patient has no symptoms or known risks for breast cancer. How should this be coded?
Answer:
Assign code V76.12, Special screening for malignant neoplasm, Breast, as the first listed diagnosis, since this was a screening mammogram
Even though a mass was found in the breast, the current visit for the mammogram is still considered a screening. Assign code 611.72, Lump or mass in breast, as an additional diagnosis
Outpatient:
Screening mammogram with positive findings Coding Clinic, Second Quarter 2003 Page: 4 Question:
An asymptomatic 65-year-old woman has a screening mammogram, which revealed a breast mass
Answer:
Assign code V76.11, Special screening for malignant neoplasm, Breast, Screening mammogram for high-risk patient, as the first-listed diagnosis, followed by code V16.3, Family history of malignant neoplasm, Breast
Note: High risk factors include a family history of breast cancer.
Outpatient:
Screening mammogram due to family history Coding Clinic, Second Quarter 2003 Page: 4
Question:
A woman with no symptoms is referred for screening mammogram. The patient is considered high risk for breast cancer secondary to a family history of breast malignancy in the mother and sister. How should this encounter be coded?
CMS considers the following patients to be high risk:
-personal history of breast cancer (V10.3)
• family history of breast cancer (V16.3)
(In Mother, Sister)
• In Daughter
• Had her first baby after age 30 (V15.89)
• Has never had a baby (V15.89)
If there is documentation of these conditions then assign V76.11 as primary dx, with above conditions as a secondary dx
Outpatient:
Screening Mammograms- Codes V76.11 High Risk
What constitutes “high risk”?
Screening mammogram with known fibrocystic disease
Answer:
Assign code V76.12, Special screening for malignant neoplasm, Other screening mammogram, as the first-listed diagnosis. Code 610.1, Diffuse cystic mastopathy, should be assigned as an additional diagnosis
Fibrocystic breast disease is a normal variant, commonly found in normal breasts usually consisting of lumps
Also called diffuse cystic mastopathy chronic cystic mastitis, fibrocystic mastopathy and mammary dysplasia.
This exam would still be considered a screening mammogram and code V76.12 assigned as the first-listed diagnosis
Outpatient:
Screening mammogram with known fibrocystic disease Coding Clinic, Second Quarter 2006 Page: 10 Question:
The physicians at our facilities order routine screening mammograms for patients with known fibrocystic disease of the breasts
Based on the guideline for screening that it is the testing for disease or disease precursors in seemingly well individuals it seems that code V76.12 would not be used since fibrocystic breast disease is documented
What should be the first-listed code for a screening mammogram on patients with fibrocystic disease of the breast?
False. Diagnostic mammograms differ from screening mammograms. Screening mammograms are for patients without apparent problems. Diagnostic mammograms are performed when there IS a problem identified, such as a breast mass, pain, discharge, etc. Diagnostic mammograms should have a diagnosis, sign, symptom or other problem documented
Outpatient:
Diagnostic mammograms:
Question: True/False? A diagnostic and screening mammograms are essentially the same and coded as such.
Answer:
Code any positive findings found on the diagnostic mammogram. If there are no reported findings, assign the reason for the test as the first listed diagnosis. In this instance, assign code 611.72, Lump or mass in breast. Do not assign code V76.12, Special screening for malignant neoplasm, Breast, because this was not a screening mammogram.
Outpatient:
Diagnostic mammograms:
A patient with a breast mass is referred to the radiology department for diagnostic mammogram. How should this be coded?
Answer:
-When a follow-up exam is done to determine if there is any evidence of recurring or metastasizing cancers and no evidence of malignancy is found, this is classified to the V67 category for follow-up
-Assign code V10.3, Personal history of malignant neoplasm, Breast, as an additional diagnosis
– If the follow-up examination demonstrates recurrence or metastasis, a follow-up code from category V67 would not be used.
Outpatient:
Follow-up mammogram
Coding Clinic, Second Quarter 2003 Page: 5 Question:
An asymptomatic patient with a history of breast cancer who is currently disease-free is referred for follow-up mammogram. What is the correct code assignment for this encounter?
It may be used in conjunction with other codes related to the patient’s health status (V49.81, Postmenopausal status, and V07.4, Postmenopausal hormone replacement therapy). The screening code should be listed before the status codes.
V82 Special screening for other conditions
V82.8X Other specified conditions
V82.81 Osteoporosis
V82.89 Other specified conditions
Outpatient:
Encounters for osteoporosis screening:
Osteoporosis screening – Dexa Bone Scan
Code V82.8X, Other specified conditions, has been expanded with two new codes. A new code has been added for encounters for osteoporosis screening. This code is to identify the patient who presents for osteoporosis screening who is otherwise asymptomatic
Answer: Assign code V82.81, Special screening for osteoporosis. Code V49.81, Postmenopausal status, may be used as an additional diagnosis
Outpatient:
Question: A postmenopausal patient is seen as an outpatient for a bone density study to evaluate for osteoporosis. She has no other signs or symptoms at the present time. What diagnosis code should be used to report this encounter?
Note: Physicians will use the terms “asthma” and “reactive airway disease” (RAD) interchangeably. When you see it documented as RAD it codes to 493.90 which codes to asthma unless it is documented by the physician “RAD, NOT as asthma” If the dx states ” RAD Not as asthma” then the code assigned is 519.9 unspec disease of respiratory
Outpatient:
Note: Physicians will use the terms “asthma” and “reactive airway disease” (RAD) interchangeably. When you see it documented as RAD it codes to 493.90 which codes to asthma unless it is documented by the physician “RAD, NOT as asthma”
If the dx states ” RAD Not as asthma” then the code assigned is 519.9 unspec disease of respiratory
Category V23 (Supervision of high-risk pregnancy)
Code this as the principal or first-listed diagnosis
These codes may be used in conjunction with pregnancy complication codes
Outpatient:
Selection of Obstetric Principal or First-listed Diagnosis:
Prenatal outpatient visits for high-risk patients?
Use subcategory 648.X for patients who have current conditions when the condition affects the management of the pregnancy, childbirth, or the puerperium. Use additional codes to identify the conditions, as appropriate. e.g.
1.) Code: 648.23 (other current conditions in mother classifiable elsewhere, but complicating pregnancy, antepartum) + 285.9 (anemia, unspec.)
2.) Code: 648.93 (current condition in mother complicating pregnancy, antepartum) +
496 (COPD)

4.) True/False? Status V codes may be used with aftercare V codes to indicate the nature of the aftercare.
Code: V54.19 aftercare for healing traumatic fx of bone.
Example: X-ray done after definitive fracture treatment of ankle. Dx on X-ray order and Indication of report states “Healing traumatic fx of ankle”. How is this coded?
Answer: Assign code V67.4, Follow-up examination, Following treatment of healed fracture, for the encounter. This is a follow-up visit for a healed fracture.
A code from category V67 is used as the first-listed diagnosis when a patient is seen for evaluation after treatment of a disease or injury has been completed and the condition no longer exists
Outpatient:
Aftercare terms to watch for in regards to fractures:
“Healed” vs. “Healing”
Follow-up visit for healed fracture: (Note: term “healed”)
Patient is an 18-year-old male who had previously sustained a comminuted right distal tibial fracture that had been treated. Is now being seen for follow-up X-rays. Conclusion states “Complete alignment and union of fracture with full range of motion” Is code V54.16 Aftercare for healing traumatic fracture of lower leg, assigned for this encounter?
Search under “admission for, examination”
In these cases, code V70.5, Health examinations would be the first listed diagnosis.
Outpatient Visits:
An example of an outpatient visit:
When a patient comes in for pre-employment physical exam
You may see a lab order with a dx of pre-employment physical
First listed diagnosis in this case would be V58.83 Encounter for therapeutic drug monitoring
of the medication Coumadin
Additional dx code V58.61 would also be used to describe long-term use of the anticoagulant
Outpatient Visits:
Another example: A patient who is on Coumadin therapy may be required to visit a Coumadin clinic weekly until the levels of medication are adjusted
Lab order dx would be Coumadin monitoring
Step 1: Review the complete outpatient documentation
Step 2: Abstract the confirmed diagnoses to be coded based on that documentation
Step 3: Assign the correct ICD-9-CM diagnosis codes, following the ICD-9-CM rules and conventions.
Step 4: Sequence the codes based on Section IV of the ICD-9-CM Official Guidelines
Outpatient:
Outpatient Code Assignment Flow: 4 steps
Primary dx code would be V57.1 for Physical therapy, as the reason chiefly responsible for the patient’s visit
Code 719.46 for the knee pain, which is the problem for which the service is being done. This would be assigned second
Outpatient:
Patients may receive only therapeutic services:
procedures done to treat conditions and injuries – during outpatient visits.
The ICD-9-CM code reported first represents the diagnosis, condition, problem, or other reason for the encounter
Examples: Physical Therapy, Occupational Therapy, Speech Therapy
For example: Physical therapy order for PT with a dx of knee pain documented
A code from category V72.8 is sequenced first
A fifth digit is required to indicate the type of pre-operative exam
The reason for the surgery is coded as an additional diagnosis
Codes would be V72.63 Pre-procedural lab exam as first listed code and 401.9 for the HTN as an additional code
Outpatient:
When a patient receives a preoperative evaluation only,
For example: A patient is planning surgery for an abdominal aortic aneurysm The patient’s primary care physician sends her for lab work for pre-op evaluation. On the lab order it is documented “Pre-op eval, HTN”
V22.0, supervision of normal first pregnancy
V22.1, supervision of other normal pregnancy
These codes are only acceptable as the primary diagnosis
For complications of pregnancy, the above codes of V22.0 and V22.1 are NOT reported with codes 630-677
Outpatient:
Routine Outpatient Prenatal Visits
The guideline for prenatal visits applies when the prenatal visit occurs and the patient has NO current complications

Patient who will be 16 yrs or less at expected time of delivery. Codes would be:
V23.81 elderly primigravida
V23.82 elderly multigravida
V23.83 young primigravida
V23.84 young multigravida
Outpatient:
ICD defines high risk pregnancy as:
V23.41 history of pre-term labor
V23.42 history of ectopic pregnancy
V23.49 other poor obstetric history
V23.3 grand multiparity
Outpatient:
Poor obstetric history includes:
For these encounters where they are checking for viability assign code V23.87
“Pregnancy with inconclusive fetal viability”
Outpatient:
This V code is assigned as the reason for an encounter to determine the viability of the pregnancy
Example: during the early weeks of pregnancy, it may be difficult for the physician to determine fetal viability. When the fetal heartbeat is not heard, an ultrasound is needed to confirm that the pregnancy is viable.

However, ICD-9-CM “Official Guidelines for Coding and Reporting” contains a list of V codes that may only be reported as principle/first listed diagnosis. Codes from this list should not be reported if they do not meet the definition of principle or first listed diagnosis.
1.) Chapter 1
2.) The organism responsible for the condition.
1.) This Chapter of the ICD-9-CM classifies infectious and parasitic diseases that are easily transmittable.
2.) The primary axis for organization of this chapter is by________?
1.) A single code assigned to designate the organism: e.g. 072.x = mumps
2.) Combination codes to identify the condition and the organism. e.g. Pneumonia due to Staphylococcus aureus = 482.41
3.) Dual Classification e.g. Pneumonia = 484.3 due to Whooping cough (Bordetella pertussis) = 033.0
(sequenced as: 033.0 Bordetella pertussis + Pneumonia 484.3)
Infectious and parasitic diseases are classified in one of several ways including:
The organism always takes precedence. In the example, Cystitis (bacillary), monilial 112.2x would be the correct selection.
In an index search for an infection where a main term contains indented subterms including those to indicate organism and others to indicate (acute) (chronic) e.g.
For a diagnosis of chronic cystitis due to monilia:
Cystitis (bacillary)
chronic 595.2x
monilial 112.2x
which subterm should be selected?
Refer to the main term “Infection” or to the main term of the organism. e.g. “Infection”, “Cryptococcal = 117.5
When an organism is specified but not indexed under the main term, for example: cryptococcal cystitis when no term for cryptococcal is located under the main term cystitis, the coder should__________?
V01.82
Code for contact or exposure to SARS-associated coronavirus?
079.82
SARS-associated coronavirus infection.
480.3
Pneumonia due to SARS-associated coronavirus
1.) 066.4x
2.) Has been expanded to 5th digit to include complications.
1.) Category used to report West Nile Virus? 2.) Expansions?
1st = residual effect, followed by:
2nd = appropriate late effect code
The infection is not coded because it is no longer present.
How should a residual conditiondue to a previous infection or parasitic infestation be coded?
1.) 010 – 018
2.) site or type
3.) method by which the tuberculosis was determined.
1.) Tuberculosis is classified to categories _______?
2.) The primary axis of tuberculosis categories are the _____ or _____ of the tuberculosis?
3.) The fifth-digit subclassification of tuberculosis is used to indicate the ____________?
False.The examples should be coded with 795.51
It is improtant to differentiate between a diagnosis of tuberculosis and a positive tuberculin skin test without a diagnosis of active tuberculosis.
True/false?
Positive results of a tuberculinskin tests including:
– nonspecific reaction to tuberlculin skin test without active tuberculosis
-Positive tuberculin skin test without active tuberculosis
-Positive PPD
-Abnormal result of Mantoux test
should be interpreted as a positive diagnosis of tuberculosis and coded from the 010 – 018 category.
Bacteremia (790.7)
The presence of bacteria in the bloodstream after trauma or mild infection. The condition is usually transient and ordinarily clears through the actions of the body’s own immune system.
1.) Septicemia
2.) Sepsis
1.) The term used by the ICD-9-CM to designate codes describing a systemic disease associated with pathological microorganisms or toxins in the blood. The old-school term is “Blood Poisoning”.
2.) Physicians may use this term interchangeabley with ________?
Systemic inflamatory response syndrome (SIRS)
__________refers to the systemic response to infection, trauma/burns,or other insult (e.g. cancer) with symptoms including fever, tachycardia, tachypnea, and leukocytosis.
Sepsis
__________ generally refers to SIRS due to infection.
1.) fever > 101.3
– heartrate > 90 BPM
– respiratory rate > 20 breaths/min
– hypotension
– SOB
– confusion/altered MS
2.) Ask the supervisor re. assigning a code. A query to get the physician to specify might be appropriate. DO NOT IGNORE clinical picture.
1.) The clinical picture for sepsis generally includes two of the following:
2.) if this clinical picture is present in the chart but there is no definitive diagnositc statement regarding “sepsis” or “SIRS” the coder should________ ?
Query the physician as to whether an additional diagnosis of sepsis (095.9x) should be included.
With a diagnosis of Septicemia (038.xx) only listed in the chart the coder should_____________?
True (clarification from physician may be needed in some instances)
True/False a diagnosis statement of “urosepsis” or “urinary tract infection” followed by a diagnosis of septicemia ususally indicates that the condition has progressed to septicemia, in which case the septicemia should be coded.
1st = underlying systemic infection (e.g. 038.xx, 112.5, etc)
2nd = Sepsis (995.91)/Severe sepsis (995.92)
3rd = other localized infection (only if present)
When sepsis or severe sepsis is the condition that, after study, necessitated the admission: How should this be coded?
A.) 1st code principle dx. (reason for admission) followed by systemic infection code (038.xx, 112.5, or 054.5), then sepsis code (995.91/995.92) as secondary dxs.
B.) The physician mus be queried for clarification to select principle dx.
How should the following be coded?
A.) sepsis/severe sepsis develops after admission?
B.) The medical record is not clear regarding whether or not sepsis was present on admission?
False. 995.9x codes are not assigned unless the term “sepsis” or “SIRS” is specifically documented and they are NEVER assigned as a principle diagnosis. (if there is a clinical picture in the chart suggesting sepsis, the physician should be queried for clarification.)
True/False? 995.9x codes are sometimes used as a principle diagnosis to indicate a clinical picture in the chart suggesting the presence of SIRS or sepsis even when these terms are not documented by the physician.

2.) If infection occurs during labor code___________?
Code 670.0x. Do not assign 0.38, or 995.91 as systemic septicemia and sepsis(non-severe) is already covered in the 670.0x code. If septic shock is present, add code 995.92 to indicate severe sepsis and also assign codes to indicate any organ dysfunction.
If sepsis/septic shock occurs during the puerperal period how should it be coded?
The provider’s documentation of the relationship between the infection and the procedure.
Sepsis due to postoperative infection is coded based on______?
1st assign complication code (e.g. 998.59 = “Other postoperative infection” or 674.3x = “Other complications of obstetrical wounds”) followed by systemic (038.xx etc.) and sepsis (995.9x) codes. Add any additional codes for organ dysfunction for cases of severe sepsis and for organism if known. Also, if septic shock occurs, assign 998.02 (“postoperative septic shock”) after 995.92 (“severe sepsis”)
How should postoperative sepsis be coded?
1st assign appropriate complication code (e.g. 999.31 = “infection due to central venous catheter” or 996.62 = infection and inflammatory reaction due to vascular device, implant, and graft”) followed by systemic (038.xx etc.) and sepsis (995.9x) codes. Add any additional codes for acute organ dysfunction for cases of severe sepsis, and for organism if known.
How should sepsis due to vascular catheter infection be coded?
1st code the noninfectious process (burn/injury) followed by systemic (038.xx etc.) and sepsis (995.9x) codes. Also code for any acute organ dysfunction for cases of severe sepsis.
How should the following be coded? A non-infectious process (burn/injury) which designated as the principle diagnosis develops infection and progresses to sepsis or severe sepsis.
1st code the systemic (038.xx etc.) and sepsis (995.9x) codes followed by the noninfectious condition (burn/injury).
How should the following be coded? Sepsis or severe sepsis is the principle diagnosis with the initiating event being a non-infectious process (burn/injury).
Either may be sequenced first.
How should the following be coded? Sepsis or severe sepsis and a non-infectious process (burn/injury) both equally meet the definition of principle diagnosis.
True
True/False? Only one SIRS code from 995.9x should be assigned for patients with sepsis or severe sepsis associated with trauma or other noninfectious conditions.
1.) 038.0
2.) 038.0 + 995.91
3.) systemic (038.xx.112.5 etc.) +
severe sepsis (995.92) +
any associated acute organ dysfunction
Code:
1.) Streptococcal septicemia
2.) Streptococcal sepsis
3.) severe sepsis
systemic (038.xx.112.5 etc.) +
severe sepsis (995.92) +
septic shock (785.52) +
any associated acute organ dysfunction
Code:
Septic shock

Other postoperative infection (998.59) +
systemic (038.xx.112.5 etc.) +
severe sepsis (995.92) +
postoperative septic shock (998.02)
Code:
Postoperative septic shock
Toxic shock syndrome (040.82)
Syndrome caused by a bacterial infection and includes symptoms of: sudden onset high fever, vomiting, watery diarrhea, and myalgia, followed by hypotension and sometimes shock.
With gram-negative bacteria sequence as:
condition + responsible oganism
Therefore, “Chronic pyelonephritis due to gram-negative bacteria” would be coded as:
Chronic pyelonephritis (590.00) + gram-negative bacteria (0 41.85)
Code/sequence:
“Chronic pyelonephritis due to gram-negative bacteria”
gram-negative bacteria =0 41.85
Chronic pyelonephritis = 590.00
1.) The physician specifically states in the chart that an infection has become drug resistant.
2.) Condition/infection + V09.xx code (fourth digit indicates the drug to which the organism/infection has become resistant)
1.) V codes (V09.xx) indicating infections with drug resistant organisms can only be assigned when____________?
2.) How are these codes sequenced?
1. False. Colonization means that a patient is a carrier – the infectious organism is present in the body without necessarily causing illness.
2. A patients carrier status is indicated as with V02.5x codes.
1.) True/False. Colonization is the same as infection.
2.) Coding to indicate that a patient is a carrier of an organism is assigned by ________?

1.) 647.6 (Other viral diseases) + 042 as an additional code.
2.) V08 would be assigned as an additional code.
1.) When an obstetric patient is identified as having any HIV infection, the correct coding/sequencing is_________?
2.) When an obstetric patient tests positive for HIV but has no signs, symptoms, or history of and HIV infection, the correct coding/sequencing for is____________?
1.) underlying condition = Mumps (072.79)
2.) manifestation = Arthritis (711.50)
correct sequence for manditory multiple coding of a manifestation and its undelying condition?
e.g. Arthritis (711.50) due to mumps (072.79)
the conditioned mentioned is documented as being present.
In situations when associated conditions may or may not be documented, the instruction to “use additional code” indicates that multiple codes should be assigned only if_________?
1.) “UTI, site not specified” – 599.0
2.) “Escherichia coli [E. coli]” E.- 041.49
Diagnostic statement indicates urinary tract infection (UTI) due to e-coli. “UTI, site not specified” listed as 599.0 includes the note “Use additional code to identify organism, such as Escherichia coli [E. coli] (E. coli code = 041.49) What is the correct coding/sequencing?
Report unconfirmed diagnosies as if established except in:
1.) Coding of HIV infection/ AIDS, cancer
3.) Outpatient coding
In an inpatient setting, what is the appropriate coding for unconfimed diagnoses ? i.e. when diagnostic statement lists diagnoses: “possible”, “probable”, “suspected” “likely”, “quest-ionable”, “?” , “rule out”,”consistent with”, “compatable with”, “indicative of”, “suggestive of”, “appears to be”, and “comparable with” 2 exceptions?
False
Physician clarification is required for confirmation of disease. If a condition is not confirmed after clarification of record, a code for abnormal findings may be appropriate.
True/False – In inpatient or outpatient coding,”borderline” diagnoses are covered under the “possible/probable” rule and coded as if confirmed.
Both codes are assigned with acute (subacute) as first listed. e.g. “Acute and chronic Bronchitis.” –
1.) 466.0 – Bronchitis – acute (subacute)
2.) 491.9 – Bronchitis – chronic
Codes for diagnoses listed as both acute (subacute) and chonic when both subterms appear at the same indentation level e.g
Bronchitis….
acute or subacute … 466.0
chronic …..491.9
are assigned and sequenced?
Only one code is assigned in this case. e.g. “Acute and chronic poliomyelitis”
=; 335.21 chronic poliomyelitis.
Codes for diagnoses listed as both acute (subacute) and chonic when when only one term is indented as a subterm with the other subterm in parenthases as a non-essential modifier. e.g.
Poliomyelitis (acute) (anterior) (epidemic) 045.9
chronic 335.21
Use the combination code. e.g. chronic and acute respiratory failure =; 518.84
Codes for diagnoses listed as both acute (subacute) and chonic when a combination code has been provided for use when a condition is described as both acute (subacute and chronic. e.g.
518.84 includes both acute and chronic respiratory failue.
disregard “acute/subacute, chronic” modifiers and just use the regular code.
Appropriate coding for when a diagnosis has no subentries listed for “acute/subacute” or “chronic”.
The condition is coded as a confirmed diagnosis. e.g. code 644.21 – “early onset of labor delivered”.
Code assignment for “impending” or “threatened” conditions that did occur? e.g. medical record indicates a diagnosis of threatened premature labor at 28 weeks gestation. Review of medical record indicates that a stillborn was delivered during the hospital stay?
1.) Assign code for “threatened” or “impending” condition. e.g. Pt is admitted with dx. of “threatened abortion” but abortion is averted. Assign code 640.0x for “threatened abortion”.
2.) Precursor condition that actually existed is coded. e.g. Pt. admitted with a dx of “impending gangrene” but gangrene is averted with prompt tx.
Code is then assigned for the presenting situation that suggested the possibility of gangrene – “redness or swelling”
Code assignment for impending or threatened conditions that did not occur? 2 possibilities:
1.) Code for “threatened” or “impending” condition exists (either under main term, or condition is indented under terms “threatened” or “impending”:
2.) No code for “threatened” or “impending” condition is indexed.
False – There is no set period of time that must elapse before a condition can be considered a late effect. Certain conditions due to trauma including “Malunion”, “Nonunion”, and “Scarring” are inherent late effects no matter how early they occur.
True/False – Set period of time must elapse before a condition can be considered a late effect.
Generally two codes are required:
1.) Residual condition – e.g. “Paralysis” – 344.40,
followed by:
2.) Late effect code for causal condition (indexed under “Late” in most cases) e.g. “Late, effects, poliomyelitis” – 138
3.) If causal condition was an injury then a late effect E code would be assigned last. In the revious example an E code would not be assigned because poliomyelitis is not an injury.
Generally, what is the appropriate coding/sequencing for late effects – e.g. “paralysis of left leg due to old poliomyelitis”?
1.) When the residual effect is not clearly stated the late effect of the causal condition is is used alone.
e.g. “Sequela of old crush injuy to foot” = 906.4 – “late effect of crushing”
2.) When no late effect code is provided in the ICD-9, but the description in the medical record indicates that condition is a late effect, only the residual condition is coded. (do not code complications from previous surgeries as late effects)
3.) Late effect code has been expanded at the 4th and 5th digit to include residual conditions, then only the combination late effect code is assigned. – (only 438 codes – “late effects of CVA” have been expanded this way)
What are three exceptions to the general guideline for coding of late effects?
False – A late effect code is generally not used with a code for a current illness or injury of the same type, but there is one exception: 438 codes “late effects of cerebrovascular disease (CVA) are assigned as additional code when a pt. with residual effects from a previous CVA is seen for a current CVA. e.g.
434.00 cerebral thrombosis, w/o mention of infarction also gets additional code of: 438.11 – late effects of CVA, with speech, language deficits/aphasia.
True/False a late effect code is never used with a code for a current illness or injury of the same type
1.) Operative approaches, openings, closures that are an integral part of the of the procedure are not coded.
2.) Operative approaches are coded when opening of body cavity is followed solely by a diagnostic procedure such as a biopsy. In this case approach such as laparotomy is sequenced first followed by a code for the biopsy.
What is the appropriate coding for operative approaches and closures.
1.) Codes have been developed to include these techniques for most procedures (combination codes) No additional code needed.
2.) When conversion to an open procedure is necessary, only code the open procedure followed by a V64.xx code to indicate the conversion.
1.) What is the appropriate coding for laparoscopic, thoracoscopic, and arthroscopic approaches?
2.) What is the appropriate coding for conversion from a laparoscopic, thoracoscopic, or arthroscopic approach to an open approach?
1.) Procedure code + code for endoscopic approach (unless directed otherwise by ICD-9, or endoscopic approach is included as part of the procedure codes description)
2.) When the endoscope is passed through more than one body cavity, the endoscopy code should indicate the most distant site.
How are other (non-laparoscopic, thoracoscopic, and arthroscopic) endoscopic approaches to procedures coded (2 guidelines)?
When a lesion removed for therapeutic/treatment purposes is sent to the lab for examination, a biopsy code is not assigned.
When should a biopsy code not be assigned even if a record uses the term “biopsy” in reporting the procedure?
Closed biopsies
Biopsies performed via needle, brush, or aspiration?
1.) If endoscopy is not included in the biopsy code,
code as: 1st endoscopy code + 2nd biopsy code.
2.) and 3.)
only code “closed biopsy” for brush and aspiration biopsies
How should closed biopsies of the following types be coded?
1.) Closed – endoscopic
2.) Closed – brush
3.) closed – aspiration
1.) no additional code required – “open” biopsy implies incision.
2.) both procedure and biopsy are coded as:
1st = definitive procedure + 2nd biopsy
3.) “needle” is a closed biopsy. In this case, the terms “open”/”closed” refer to the biopsy itself not the surgical procedure. Coded as:
1st = definitive procedure + 2nd “closed” biopsy
4.) 1st = definitive procedure + 2nd = biopsy
How should open biopsies of the following types be coded?
1.) open (by way of incision) biopsy only.
2.) biopsy is incidental to removal of other tissue during a procedure.
3.) needle (closed) biopsy during an open surgical procedure.
4.) biopsy immediately before a surgical procedure begins (i.e. rapid-frozen-section exam)
an associated diagnostic code e.g. “retinal detachment”
A report with a code for a diagnosis-related procedure e.g. “repair of retinal detachment” must also contain__________?
1.) V64.xx codes
2.) Code to the extent to which procedure was actually performed. In examples code only for: incision, endoscopy, or exploration of site, respectively.
3.) Procedure is still coded as performed.
What are the guidelines for coding the following:
1.) Cancelled procedures?
2.) Incomplete procedures – e.g. not completed because:
incision only, endoscopic approach unable to reach site,
cavity or space entered but procedure not competed?
3.) Procedure failed e.g. completed but goal of procedure not achieved?
Coder must determine which site is involved in the revision. e.g. if peritoneal only, then code 54.95 “incision of the peritoneum”, if ventricular site revised, then code 02.42 “replacement of ventricular shunt”, if both sites are involved, then both codes should be assigned.
Appropriate coding for ventriculoperitoneal shunt?
Code for the following:
1.) stent insertion (if stent insertion is part of a coronary angioplasty, code the angioplasty 1st.)
2.) number of vessels treated
3.) number of stents inserted
4.) procedure on vessel bifurcation (if vessel bifurcation present)
Required types of codes for stent insertion?
1.) 92.3x = stereotactic radiosurgery
2.) 93.59 = immobilization
Required coding for stereotactic radiosurgery?
1.) code for specific procedure performed
2.) code from subcategory 00.3x to indicate CAS.
Required coding for computer assisted surgery (CAS)?
1.) code for specific procedure performed
2.) code from subcategory 17.4x to indicate robotic assisted surgery.
Required coding for robotic assisted procedures?
