What is a composite APC?


Composite APCs provide a single payment for a comprehensive diagnostic and/or treatment service that is defined, for purposes of the APC, as a service typically reported with multiple HCPCS codes.  When HCPCS codes that meet the criteria for payment of the composite APC are billed on the same date of service, CMS makes a single payment for all of the codes as a whole, rather than paying individually for each code.
