B97.33
BillableHuman T-cell lymphotrophic virus, type I [HTLV-I] as the cause of diseases classified elsewhere
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code indicates that a patient has been infected with Human T-cell lymphotrophic virus type I (HTLV-I), which is causing or contributing to another disease that is documented separately. HTLV-I is a virus that can lead to serious conditions like adult T-cell leukemia or tropical spastic paraparesis.
Coding Tips
- •This is a secondary code used only when HTLV-I is identified as the underlying cause of another documented condition; always code the resulting disease or condition as the primary diagnosis
- •Do not use this code for asymptomatic HTLV-I carriers or for screening purposes; it requires evidence that the virus is actively causing disease
