Y63.6 — Underdosing and nonadministration of necessary drug, medicament or biological substance
Billable / specific codeICD-10-CM
Y63.6 is a billable, specific ICD-10-CM code for underdosing and nonadministration of necessary drug, medicament or biological substance. It is valid for submission on a claim.
Risk adjustment
Y63.6 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.
