ICD-10 Code B97.35 – Human immunodeficiency virus, type 2 [HIV 2] as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B97.35 – Human immunodeficiency virus, type 2 [HIV 2] as the cause of diseases classified elsewhere
What it is
This code identifies HIV-2 as the infectious cause of another condition classified elsewhere. Use it when the record shows HIV-2 is responsible for a separate diagnosis, not as the primary disease itself.
Clinical signs
Clinical features vary; refer to documentation. Records may note HIV-2 infection with an associated opportunistic, infectious, or other related condition that the clinician links to HIV-2.
When to use this code
Use B97.35 when the provider documents HIV-2 as the cause of a condition coded elsewhere, such as an associated infection or complication. Pair it with the manifestation or related diagnosis code as instructed in the chart. If the note only says “HIV” without type, check documentation before assigning this code.
Do not use for
Do not use this code for HIV-1, unspecified HIV, or a standalone HIV diagnosis without a linked condition. Do not use it when the record does not clearly identify HIV-2 as the cause.
Coding tip
Confirm both the HIV type and the associated condition in the provider’s documentation before coding.
