Which MS-DRGs does C17.1 group to?
C17.1 sits in MDC 06 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 374Digestive Malignancy with MCCmedical
- 375Digestive Malignancy with CCmedical
- 376Digestive Malignancy without CC/MCCmedical
As a secondary diagnosis, C17.1 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

- Kaposi's sarcoma of gastrointestinal sites (C46.4)
Excludes1 — never code together — inherited from C17
The conditions below can never be reported together with C17.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Excludes2 — not included here — inherited from C15-C26
