Knee Arthroplasty

The Knee Arthroplasty cost measure evaluates clinicians’ risk-adjusted cost to Medicare for beneficiaries who receive this procedure. The cost measure score is a clinician’s average risk-adjusted cost for the episode group averaged across all episodes attributed to the clinician. This procedural measure includes costs of services that are clinically related to the attributed clinician’s role in managing care during the 30 days prior to the clinical event that opens or ‘triggers’ the episode, through 90 days after the trigger. Beneficiary populations eligible for the Knee Arthroplasty measure include Medicare beneficiaries enrolled in Medicare Parts A and B during the performance period.
