General Question for the Week of June 5, 2017

General Compliance Question of the Week


Is there an appeal process for units of service (UOS) denied based on medically unlikely edits (MUEs)?


UOS denied due to a MUE, whether a claim line MUE or date-of-service MUE, may be appealed. Appeals should be submitted to local contractors, not the MUE contractor. Contractors adjudicating appeals will determine whether:

  • The appropriate HCPCS/CPT code is reported
  • The appropriate number of UOS is reported
  • Whether the UOS reported are medically reasonable and necessary.

Contractors may pay UOS in excess of the MUE value if the contractor determines that they are medically reasonable and necessary.
