D13.1

D13.1 — Benign neoplasm of stomach

Billable / specific codeICD-10-CM

D13.1 is a billable, specific ICD-10-CM code for benign neoplasm of stomach. 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 carcinoid tumor of the stomach (D3A.092)

Other codes that can never be billed with D13.1

These codes carry an Excludes1 note pointing at D13.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D13.1 alone.

K31.7Polyp of stomach and duodenum

Risk adjustment

D13.1 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.

Medicare coverage

D13.1 is named in 12 Medicare coverage policies — 12 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
