B64
B64 — Unspecified protozoal disease
Billable / specific codeICD-10-CM
B64 is a billable, specific ICD-10-CM code for unspecified protozoal disease. It is valid for submission on a claim.
Risk adjustment
B64 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.
How B64 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to B64.
