Medically Unlikely Edits: units per day
The most units of Q3031 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.
- practitioner
- 1 unit MAI 3: Date of Service Edit: Clinical · Nature of Service/Procedure
- outpatient
- 1 unit 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 2026Q4.
