In its 2022 final payment rule for ASCs and hospital outpatient departments (HOPD), the Centers for Medicare & Medicaid Services (CMS) finalized its proposal to reverse policy changes from the previous administration that added a significant number of codes to the ASC Covered Procedures List (ASC-CPL) and began the process of eliminating the inpatient-only (IPO) list, with a few modifications. CMS also continued to use the hospital market basket to update ASC payments for calendar year (CY) 2022. This policy is currently slated to run through CY 2023 as the agency assesses its impact on volume migration.
