Total Knee Arthroplasty (TKA) Removal from the Medicare Inpatient-Only (IPO) List and Application of the 2-Midnight Rule

Published 01/25/2019

The Centers for Medicare & Medicaid Services (CMS) removed the Current Procedural Terminology (CPT) code describing TKA procedures from Medicare’s Inpatient-Only List (IPO) effective January 2018. This allows TKA procedures to be performed on an inpatient or outpatient basis. In other words, it allows Medicare payment to be made to the hospital for TKA procedures regardless of whether a beneficiary is admitted to the hospital as an inpatient or as an outpatient, assuming all other criteria are met. This does not have any impact on CMS’ 2-midnight policy.
