Point32 Inpatient Setting for Elective Total Joint Arthroplasty; Hip and Knee Form

Harvard Pilgrim HealthCare Medical Policy

Inpatient Setting for Elective Total Joint Arthroplasty; Hip and Knee

Subject: Inpatient Setting for Elective Total Joint Arthroplasty; Hip and Knee

Background: Providers and patients have recognized the benefits associated with procedures performed in the outpatient setting with same day discharge to home. The Centers for Medicare & Medicaid Services (CMS) have recently made decisions to remove total knee arthroplasty and total hip arthroplasty from the Medicare inpatient-only (IPO) list of procedures and allow for these procedures to be performed in an outpatient setting.

Although it is appropriate for total joint arthroplasty procedures, hip and knee, to be performed in the outpatient setting, there is a select group of patients for whom elective hip or knee arthroplasty may be more appropriately performed in the inpatient setting.

Note: Total hip arthroplasty and total knee arthroplasty procedures are subject to National Imaging Associates' (NIA) prior authorization requirements. Refer to Spinal Conditions Management Programs page.

Policy and Coverage Criteria:

Policy and Coverage Criteria: The Plan will allow elective total joint arthroplasty, hip and knee, to be performed in the inpatient setting for certain groups of patients when criteria are met.
