Medically Unlikely Edits — units per day

The most units of G2004 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 · Nature of Service/Procedure

MAI 3 — Date of Service Edit: Clinical · Nature of Service/Procedure

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.
