18 Questions

Other diagnoses would be B20 followed by additional diagnosis codes for all reported HIV-related ______

conditions

Whether the patient is newly diagnosed or has had previous admissions/encounters for HIV ______ is irrelevant to the sequencing decision

conditions

Asymptomatic human immunodeficiency virus Z21, Asymptomatic human immunodeficiency virus [HIV] infection status, is to be applied when the patient without any documentation of symptoms is listed as being “HIV ______”

positive

Patients with inconclusive HIV serology, but no definitive diagnosis or manifestations of the illness, may be assigned code R75, Inconclusive laboratory evidence of human immunodeficiency virus [HIV]

infection

During pregnancy, childbirth or the puerperium, a patient admitted (or presenting for a health care encounter) because of an HIV-related illness should receive a principal diagnosis code of O98.7-, Human immunodeficiency [HIV] disease complicating ICD-10-CM Official Guidelines for Coding and Reporting FY 2024 Page 21 of 120 pregnancy, childbirth and the puerperium, followed by B20 and the code(s) for the HIV-related ______(es)

illness

Code only confirmed cases of HIV ______

infection/illness

If a patient is admitted for an HIV-related condition, the principal diagnosis should be B20, Human immunodeficiency virus [HIV] ______

disease

An exception to this guideline is if the reason for admission is hemolytic-uremic syndrome associated with HIV ______

disease

Assign code D59.31, Infection-associated hemolytic-uremic syndrome, followed by code B20, Human immunodeficiency virus [HIV] ______

disease

If a patient with HIV disease is admitted for an unrelated condition, the code for the unrelated condition should be the ______ diagnosis

principal

Match the following ICD-10 codes with their descriptions:

A00-B99 = Certain Infectious and Parasitic Diseases U07.1 = COVID-19, virus identified U09.9 = Post-COVID-19 condition, unspecified D59.31 = Infection-associated hemolytic-uremic syndrome

Match the following guidelines with the corresponding scenario:

Code only confirmed cases of HIV infection/illness. = Exception to the hospital inpatient guideline Section II, H. Patient admitted for HIV-related condition. = Principal diagnosis should be B20, Human immunodeficiency virus [HIV] disease. Patient with HIV disease admitted for unrelated condition. = The code for the unrelated condition should be the principal diagnosis. During pregnancy, childbirth or the puerperium, a patient admitted because of an HIV-related illness. = Principal diagnosis code of O98.7-, Human immunodeficiency [HIV] disease complicating pregnancy. Patients with inconclusive HIV serology, but no definitive diagnosis or manifestations of the illness. = May be assigned code R75, Inconclusive laboratory evidence of human immunodeficiency virus [HIV].

Match the following statements with their corresponding exception to coding guidelines:

Confirmation of HIV infection/illness does not require positive serology or culture for HIV. = Provider's diagnostic statement that the patient is HIV positive or has an HIV-related illness is sufficient. Exception to coding guideline if reason for admission is hemolytic-uremic syndrome associated with HIV disease. = Assign code D59.31, Infection-associated hemolytic-uremic syndrome, followed by code B20, Human immunodeficiency virus [HIV] disease. Whether the patient is newly diagnosed or has had previous admissions/encounters for HIV is irrelevant to the sequencing decision. = An exception to this guideline. Other diagnoses would be B20 followed by additional diagnosis codes for all reported HIV-related conditions. = Exception to coding guideline for patient admitted for an HIV-related condition.

Match the following HIV-related conditions with their corresponding ICD-10-CM codes:

Asymptomatic human immunodeficiency virus (HIV) infection status = Z21 Inconclusive laboratory evidence of HIV = R75 Confirmed HIV diagnosis = B20 HIV disease complicating pregnancy, childbirth, and the puerperium = O98.7

Match the following guidelines with their corresponding scenarios:

Applying code Z11.4 for HIV screening = Encounters for testing for HIV Using code B20 as principal diagnosis = Admission for an HIV-related illness Applying code R75 for inconclusive HIV serology = Patients with inconclusive HIV serology Using code O98.7 as principal diagnosis during pregnancy = HIV infection in Pregnancy, Childbirth and the Puerperium

Match the following terms with their correct application scenarios:

Newly diagnosed patient or previous admissions for HIV conditions = Irrelevant to the sequencing decision Documentation of symptoms listed as 'HIV positive' = Asymptomatic human immunodeficiency virus (HIV) infection status Known prior diagnosis of an HIV-related illness = Previously diagnosed HIV-related illness Admission for unrelated condition in a patient with HIV disease = Unrelated condition as principal diagnosis

Match the following terms with their correct application scenarios:

Use of code D59.31 followed by B20 = Infection-associated hemolytic-uremic syndrome associated with HIV Principal diagnosis code O98.7 followed by B20 and related codes = HIV disease complicating pregnancy, childbirth, and the puerperium Use of code Z21 during pregnancy, childbirth, or the puerperium = Asymptomatic HIV infection status during pregnancy, childbirth, or the puerperium Use of B20 on every subsequent admission/encounter after developing an HIV-related illness = Previously diagnosed HIV-related illness

Match the following scenarios with their corresponding exceptions or additional instructions:

Exception to using B20 as principal diagnosis for hemolytic-uremic syndrome associated with HIV = Assign code D59.31 followed by code B20 Exception to using Z21 during pregnancy, childbirth, or the puerperium when admitted for an unrelated condition = Use codes O98.7- and Z21 during pregnancy, childbirth, or the puerperium Exception to using R75 for inconclusive HIV serology in certain cases = No definitive diagnosis or manifestations of the illness Exception to using Z11.4 for HIV screening in case of signs or symptoms being present = Code the signs and symptoms

Test your knowledge on coding confirmed cases of HIV infection, as well as understanding the guidelines for hospital inpatient cases related to HIV. This quiz covers the coding and documentation requirements for certain infectious and parasitic diseases.
