Medically Unlikely Edit (MUE)

Medicare caps 0251U at 1 unit per date of service for practitioner claims (MAI 3 - date of service edit (clinical): units above the MUE may pay with documentation on appeal), rationale: Nature of Analyte. Units above the cap are denied unless the edit's adjudication rules allow an appeal with documentation.
