Z11.9 — Encounter for screening for infectious and parasitic diseases, unspecified
Billable / specific codeICD-10-CMPOA exempt
Z11.9 is a billable, specific ICD-10-CM code for encounter for screening for infectious and parasitic diseases, unspecified. It is valid for submission on a claim.
Risk adjustment
Z11.9 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.
