D23.5Other benign neoplasm of skin of trunk

Billable / specific codeICD-10-CM

D23.5 is a billable, specific ICD-10-CM code for other benign neoplasm of skin of trunk. 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.

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Other benign neoplasm of anal margin
  • Other benign neoplasm of anal skin
  • Other benign neoplasm of perianal skin
  • Other benign neoplasm of skin of breast

Other codes that can never be billed with D23.5

These codes carry an Excludes1 note pointing at D23.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D23.5 alone.

  • D12.9Benign neoplasm of anus and anal canal

Risk adjustment

D23.5 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

D23.5 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.
