View CMS’ Medically Unlikely Edits web page for details on MUE. Access the MUE tables as appropriate to your provider’s line of business.

Medicare Part B providers may view a full list of published HCPCS/CPT codes subject to MUE and their maximum allowed units in the Practitioner Services MUE Table.

• Always use the current version.
• Some MUE values are confidential, therefore, certain CPT/HCPCS codes will not be published in the posted files. The confidential status of an MUE is subject to change.
