Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Benign stromal tumors of abdomen
Other codes that can never be billed with D21.4
These codes carry an Excludes1 note pointing at D21.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D21.4 alone.
- D13Benign neoplasm of other and ill-defined parts of digestive system
Risk adjustment
D21.4 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
D21.4 is named in 8 Medicare coverage policies — 8 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

- A56421Billing and Coding: CT of the Abdomen and Pelvis
