Chapter 4 - ICD-10-CM Coding Chptrs 1-11 Flashcards
HIV infection/illness
Only coded for confirmed cases. Physicians statement of HIV positive or HIV related illness is enough to code.
HIV proper sequencing
When admitted for HIV related conditions B20 is coded first followed by additional codes for HIV related conditions
Conditions always considered HIV related
Kaposi’s sarcoma, lymphoma, pneumocystis carinii pneumonia (PCP) cryptococcal meningitis, and cytomegalovirus disease. All considered opportunistic infections.
Admitted for a condition unrelated to HIV
Code the unrelated diagnosis first. B20 is reported as an additional diagnosis, as are any HIV related conditions. HIV affects treatment of any condition in addition to any reported HIV related conditions. Documentation should support reporting of HIV
Asymptomatic human immunodeficiency virus.
Z21. HIV positive but no symptoms of an HIV related illness. Do not use if AIDS term is used.
Inconclusive lab evidence of HIV
R75 is used when patient’s have inconclusive HIV serology, and no definitive diagnosis or manifestations of the illness.
HIV status during pregnancy, childbirth, or the puerperium
Reported from the subcategory 098.7. Codes from chapter 15 always take sequencing priority.
Encounter for screening for HIV
Z11.4 is used. If signs, symptoms, or illness or confirmed HIV diagnosis be tested coded the sign, symptoms, or the diagnosis. If test is positive code B20
Patient suspects contact with HIV
Code Z20.6
Resistance to anti microbial drugs
Z16. Used if infection is antibiotic resistant and the infection code does not identify antibiotic resistance
Sepsis
Refers to an infection due to an organism that triggers a systemic inflammatory response, or systemic inflammatory response syndrome (SIRS)
Severe sepsis
Associated with acute organ failure. Requires a minimum of two codes. First code underlying systemic infection then code from R65.2 for severe sepsis.
Organ dysfunction not related to sepsis
Do not code severe sepsis.
Urosepsis
Non specific term and should not be considered synonymous with sepsis. Needs further clarification from provider.
Septic shock
Circulatory failure associated with severe sepsis
Admission for sepsis or severe sepsis and a localized infection
Code the systemic infection first then the localized infection second
Admitted for localized infection then sepsis develops after admission
Code the localized infection first then the appropriate sepsis/severe sepsis code.
Post procedural sepsis
If there is a causal relationship between procedure and sepsis code first the complication followed by the code for the specific infection.
Non-infectious process that leads to sepsis
If the non-infectious condition meets the definition for principal diagnosis it should be coded first followed by the code for the resulting infection.

Do not contain precancerous or cancerous cells.
Uncertain behavior
Needs to be noted by a pathologist. Neoplasm of transition. Not benign and not malignant.
Unspecified neoplasm
Provider did not wait for pathology report. Recommended to wait for the pathology to be reported.

Metastatic
Indicates a secondary malignancy
Anemia caused by cancer
Code malignancy first then the anemia
Anemia caused by chemo or radiotherapy
Code first the anemia followed by the codes for the for the neoplasm and then the adverse affect code
Successful treatment of a neoplasm
Inappropriate to code for the neoplasm. Use a code for the personal history of malignant neoplasms
Surgery followed by chemo or radiation in the same visit
Neoplasm listed as primary followed by codes for the therapy.
Encounter with main reason for administration of chemo, immuno, or radiotherapy
Report the proper Z Code first followed by the code for the neoplasm even if it is removed. When treatment for an eradicated neoplasm is complete then code from the history section.
Complications during chemo, immuno, or radiotherapy
Code for therapy first then the complication.
Pregnant patient with malignant neoplasm
Code from subcategory O9A.1- is sequenced first then the code for the neoplasm
Complication associated with a neoplasm
Complication is coded first then the neoplasm code. Exception is anemia.

Code first the fracture if it is the focus of the treatment. If not then code the neoplasm first
Malignant neoplasm of transplanted organ requires:
3 codes. First the transplant complication, then C80.2,followed by the code for the malignancy
