The MUE table is straightforward with a column for the CPT/HCPCS code and a column for the MUE limit. An MUE for a HCPCS/CPT code is the maximum units of service that a provider would report under most circumstances for a single beneficiary on a single date of service. Although CMS publishes most MUE values on its website, other MUE values are confidential and are for CMS and CMS Contractors' use only. The NCCI table includes code pairs that generally should not be reported together for a number of reasons as explained in the Coding Policy Manual.
