0TWB0MZ

Potential MS-DRG Relationships (FY2026)

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 6 MS-DRGs:

• MDC 11 — Minor Bladder Procedures: DRG 662, DRG 663, DRG 664
• MDC 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909

From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
