Billable / specific codeICD-10-CM

E53.1 is a billable, specific ICD-10-CM code for pyridoxine deficiency. It is valid for submission on a claim.

Risk adjustment

E53.1 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.
