Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

benign carcinoid tumors of the small intestine (D3A.01-)
benign neoplasm of ileocecal valve (D12.0)

Excludes1 inherited from the categories above D13.3

These are not written on D13.3, but they bind it: a note on a category applies to every code beneath it. Billing D13.3 with anything listed here is a denial.

Written on D13 — Benign neoplasm of other and ill-defined parts of digestive system

benign stromal tumors of digestive system (D21.4)

Risk adjustment

D13.3 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.

Code history

D13.3 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
