0KR447Z ICD-10-PCS Code: Replacement of Tongue, Palate, Pharynx Muscle with Autologous Tissue Substitute, Percutaneous Endoscopic Approach

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 15 MS-DRGs:

• MDC 01 — Peripheral, Cranial Nerve and Other Nervous System Procedures: DRG 040, DRG 041, DRG 042
• MDC 08 — Soft Tissue Procedures: DRG 500, DRG 501, DRG 502
• MDC 09 — Other Skin, Subcutaneous Tissue and Breast Procedures: DRG 579, DRG 580, DRG 581
• MDC 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
• MDC 24 — Other O.R. Procedures for Multiple Significant Trauma: DRG 957, DRG 958, DRG 959

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