[
As previously communicated, there was a change to the processing of claim
service units for professional claims that went into effect November 1, 2013.
As a result, Medically Unlikely Edits (MUE) are applied to both professional
and facility claims.
An MUE is assigned to certain HCPCS/CPT? codes identifying the
maximum units of service a provider performs on a patient on a given date of
service.
Note: Claim lines with billed units that exceed the Centers for
Medicare & Medicaid Services (CMS)-published MUE values will be rejected on a
pre- and/or post-payment basis.
CMS updates the MUE values on a quarterly basis coincident with each
quarterly version of MUE. For a complete listing of CMS-published MUE values,
visit the Medically Unlikely Edits
section of the CMS website and select the applicable MUE Table under the
Related Links header at the bottom of the page.
