Inpatient Payment Groups (MS-DRG)
MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0 (FY2026), Appendix B.
- MS-DRG 444 — DISORDERS OF THE BILIARY TRACT WITH MCC (MDC 07)

- MS-DRG 446 — DISORDERS OF THE BILIARY TRACT WITHOUT CC/MCC (MDC 07)
