HCPCS codes are organized by body systems that are sometimes referred to as a subsections of surgical and medical sections.

Allowed Charges

Allowed Charges represent the amounts used to calculate payment for billed procedures as determined by the Medicare contractor. For ASCs, allowed charges typically are the total wage-adjusted payment for a service in a specific geographic area, and include both the Medicare program payment and beneficiary copayment. Allowed charges values are represented in whole dollars with no cents.

Allowed Services

Allowed Services represent the number of procedures that the Medicare contractor allowed the supplier to bill. This number reflects total services and does not reflect application of a multiple procedure discount. This is a count of service units provided, not cases or patients. Multiple units of service can be provided to a single patient during a visit.
