The Centers for Medicare and Medicaid Services (CMS) made several changes to the pulmonary rehabilitation (PR) benefit in its update to the 2022 physician fee schedule (86 FR 65244 – 65250). CMS acknowledged the similarities between PR and cardiac rehabilitation (CR) programs and made conforming changes to enable stakeholders with interest in both programs to compare requirements and implement programs more easily. Revisions to definitions and regulatory text now align and conform to CR programs. This document notes the changes as outlined in the final rule.
