D23.0 — Other benign neoplasm of skin of lip
D23.0 is a billable, specific ICD-10-CM code for other benign neoplasm of skin of lip. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- benign neoplasm of vermilion border of lip (D10.0)
Other codes that can never be billed with D23.0
These codes carry an Excludes1 note pointing at D23.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D23.0 alone.

Risk adjustment
D23.0 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
D23.0 is named in 15 Medicare coverage policies — 15 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
