D15.0

D15.0 — Benign neoplasm of thymus

Billable / specific codeICD-10-CM

D15.0 is a billable, specific ICD-10-CM code for benign neoplasm of thymus. 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 thymus (D3A.091)

Other codes that can never be billed with D15.0

These codes carry an Excludes1 note pointing at D15.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D15.0 alone.

D35Benign neoplasm of other and unspecified endocrine glands
E32.8Other diseases of thymus
D21.3Benign neoplasm of connective and other soft tissue of thorax

Risk adjustment

D15.0 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

D15.0 is named in 11 Medicare coverage policies — 11 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
