Allowed units

Can you please let us know how many units of 87798 can be billed per day for WPS MAC (Wisconsin physician service).

Hello Apurva,

Thank you for your question.


As per CMS MUE Guidelines, the maximum allowable units per day for CPT® code 87798 is 13, that indicates, it is the maximum units of service that a provider would report under most circumstances for a single beneficiary on a single date of service.


Also, this test may be performed multiple times for different organisms. In this case, 87798 can be reported for the initial organism and 87798-59 for the additional organisms. However, if one test is performed and 3 results are obtained for a single organism, only one unit may be reported for the single test.


Note: CMS releases the Medically Unlikely Edits (MUE) data and in general, all the Medicare Administrative Contractor (MAC) follow the MUE data released by the CMS.


Hope that helps!
