Comprehensive Care for Joint Replacement (CJR) Model

MidState Medical Center has been selected by the Centers for Medicare & Medicaid Services as a participant hospital in its Comprehensive Care for Joint Replacement (CJR) model.

The Comprehensive Care for Joint Replacement (CJR) Model aims to support better and more efficient care for beneficiaries undergoing the most common inpatient surgeries for Medicare beneficiaries: hip and knee replacements (also called lower extremity joint replacements or LEJR). This model tests bundled payment and quality measurement for an episode of care associated with hip and knee replacements to encourage hospitals, physicians, and post-acute care providers to work together to improve the quality and coordination of care from the initial hospitalization through recovery.
