Payment standardization is the process of calculating standardized claim payment amounts that allow for the measurement and analysis of provider resource use by CMS and researchers. For example, standardized payment amounts may be used in a variety of CMS performance programs to evaluate and compare provider resource use for services covered by Medicare Part A, Part B, and Part D programs.
Medicare Part A and Part B Payment Standardization
Medicare Part A and Part B payment standardization allows for the evaluation of costs for all services covered under both programs. Payment standardization for Part A and Part B claims ensures that the same services are assigned comparable amounts, regardless of provider type and geographic area.
The Part A and Part B standardization methodology documentation can be found in the 'Attachments' section below, including one document with a basic overview of the methodology and a separate document outlining the technical details of the standardization methodology for those looking to replicate the standardized allowed amount calculation.
Medicare Part D Payment Standardization
Part D payment standardization allows for the evaluation of costs for prescription drugs covered under the Medicare Part D program. Part D standardization ensures that drugs with the same clinical characteristics (i.e., active ingredient, strength, dosage form, and route of administration) and brand/generic status have the same unit price, regardless of drug manufacturer, plan, or distributing pharmacy.
