D55.8 — Other anemias due to enzyme disorders
D55.8 is a billable, specific ICD-10-CM code for other anemias due to enzyme disorders. It is valid for submission on a claim.
Risk adjustment
D55.8 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.
