Billable / specific codeICD-10-CM
D04.4 is a billable, specific ICD-10-CM code for carcinoma in situ of skin of scalp and neck. It is valid for submission on a claim.
Risk adjustment
D04.4 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.
Medicare coverage
D04.4 is named in 35 Medicare coverage policies — 35 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
