Potential MS-DRG Relationships (FY2026)

The MS-DRG grouper treats this as a non-operating-room procedure. It appears in the surgical logic of 1 MS-DRG:

  • MDC 04 — Respiratory System Diagnosis with Ventilator Support: DRG 208

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