B97.3 — Retrovirus as the cause of diseases classified elsewhere
Is B97.3 billable?
No — B97.3 is a non-billable header code. B97.3 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 7 billable codes beneath B97.3.

Excludes1 — never code together
The conditions below can never be reported together with B97.3 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- Human immunodeficiency virus [HIV] disease (B20)
Use additional code — inherited from Chapter 1
Report an additional code alongside B97.3 to fully describe the condition. B97.3 is sequenced first.
- code to identify resistance to antimicrobial drugs (Z16.-)
Excludes2 — not included here — inherited from Chapter 1
The conditions below are not part of B97.3, but a patient may have both at the same time. When documentation supports it, B97.3 and the excluded code may both be reported.
- carrier or suspected carrier of infectious disease (Z22.-)
- certain localized infections - see body system-related chapters
- infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-)
- infectious and parasitic diseases specific to the perinatal period (P35-P39)
- influenza and other acute respiratory infections (J00-J22)
