Medically Unlikely Edits — units per day
The most units of G0329 Medicare will pay on one date of service. Bill more on a single line and it is denied. The limit is not the same in every setting, so the row that matters is the one matching the claim you are building.

- 1 unit MAI 3 — Date of Service Edit: Clinical · Code Descriptor / CPT Instruction

- 1 unit MAI 3 — Date of Service Edit: Clinical · Code Descriptor / CPT Instruction
The adjudication indicator decides whether exceeding the limit is worth appealing at all: MAI 1 is a line edit you can support with documentation, MAI 3 is a date-of-service edit that is also appealable, and MAI 2 is absolute — no documentation overrides it. CMS MUE 2026Q3.
