0NWW47Z ICD-10-PCS Code: Revision of Autologous Tissue Substitute in Facial Bone, 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 3 MS-DRGs:

• MDC 03 — Other Ear, Nose, Mouth and Throat O.R. Procedures: DRG 143, DRG 144, DRG 145

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