F00ZTZZ ICD-10-PCS Code: Dichotic Stimuli Assessment

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

The MS-DRG grouper treats this as a non-operating-room procedure. It appears in the surgical logic of 2 MS-DRGs:

• MDC 23 — Rehabilitation: DRG 945, DRG 946

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