APC Codes

APC's or Ambulatory Payment Classifications are outpatient services allocated into groups with assigned fixed payment amounts that are maintained by CMS as part of the Medicare Outpatient Prospective Payment System (OPPS). The APC coding system allows hospitals to be reimbursed by the U.S. government for Medicare outpatient services. APC codes are reported on claims with HCPCS Level I (CPT) codes and HCPCS Level II codes.

The APC detail page gives you a list of all associated CPT/HCPCS codes that are paid under the respective APC.
