Data are from the Medicare Ambulatory Surgical Center Payment System Limited Data Set.
- Procedure Type
- Procedures can be grouped into clinically coherent categories in order to facilitate analysis.
- 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.
