Explanation of columns

  • Number: Number of services provided; note that the metrics used to count the number provided can vary from service to service.
  • Unique: Number of distinct Medicare beneficiaries (patients) receiving the service.
  • Unique / day: Number of distinct Medicare beneficiary/per day services. Since a given beneficiary may receive multiple services of the same type (e.g., single vs. multiple cardiac stents) on a single day, this metric removes double-counting from the line service count to identify whether a unique service occurred.
  • Allowed amount: Average of the Medicare allowed amount for the service; this figure is the sum of the amount Medicare pays, the deductible and coinsurance amounts that the beneficiary is responsible for paying, and any amounts that a third party is responsible for paying.
  • Submitted: Average of the charges that the provider submitted for the service.
  • Payment: Average amount that Medicare paid after deductible and coinsurance amounts have been deducted for the line item service.
