What is the CMS Medically Unlikely Edit (MUE) program?
The CMS Medically Unlikely Edit (MUE) program was developed to reduce the paid claims error rate for Medicare claims. MUEs are designed to reduce errors due to clerical entries and incorrect coding based on anatomic considerations, HCPCS/CPT code descriptors, CPT coding instructions, established CMS policies, nature of a service/procedure, nature of an analyte, nature of equipment, and unlikely clinical treatment.
What is a Medically Unlikely Edit (MUE)?
An MUE (Medically Unlikely Edit) is a unit of service (UOS) edit for a Healthcare Common Procedure Coding System (HCPCS)/Current Procedural Terminology (CPT) code for services rendered by a single provider/supplier to a single beneficiary on the same date of service. The ideal MUE is the maximum UOS that would be reported for a HCPCS/CPT code on the vast majority of appropriately reported claims. The MUE program provides a method to report medically reasonable and necessary UOS in excess of an MUE.
