Z22.6
Z22.6 — Carrier of human T-lymphotropic virus type-1 [HTLV-1] infection
Billable / specific codeICD-10-CMPOA exempt
Z22.6 is a billable, specific ICD-10-CM code for carrier of human t-lymphotropic virus type-1 [htlv-1] infection. It is valid for submission on a claim.
Risk adjustment
Z22.6 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
