Its 2026 Q4 MUEs per date of service: practitioner 1 (MAI 2, Code Descriptor / CPT Instruction); hospital outpatient 1 (MAI 2, Code Descriptor / CPT Instruction). The practitioner MUE is a date-of-service policy edit: units above the limit deny even when split across lines, and appeals rarely succeed.
| Setting | MUE (units/DOS) | MAI | CMS rationale |
|---|---|---|---|
| Practitioner services | 1 | 2 Date of Service Edit: Policy | Code Descriptor / CPT Instruction |
| Facility outpatient hospital | 1 | 2 Date of Service Edit: Policy | Code Descriptor / CPT Instruction |
