Billable

Retrovirus infections, not elsewhere classified

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Retrovirus infections are infections caused by retroviruses (viruses that use reverse transcriptase) that are not classified elsewhere, including some non-HIV retroviruses.

Coding Tips

  • Confirm this is not HIV infection, which has its own specific coding under B20-B24
  • Document the specific retrovirus type if identified to support medical necessity
