On October 1, 2016, the Centers for Medicare and Medicaid Services (CMS) updated its list of Medically Unlikely Edits (MUEs). The MEU program is designed to reduce the paid claims error rate for Part B claims. The program operates by estimating the maximum number of units of service that a provider/supplier would report under most circumstances for a single beneficiary on a single date of service. A claim that submits units of service in excess of this threshold will typically be denied by the Medicare Administrative Contractor.
