On July 13, 2023, CMS placed on public display a proposed rule relating to the Medicare physician fee schedule (PFS) for CY 2024 and other revisions to Medicare Part B policies. The proposed rule was published in the August 7, 2023, issue of the Federal Register. If finalized, policies in the proposed rule generally would take effect on January 1, 2024. The 60-day comment period ends at close of business on September 11, 2023. HFMA is providing a summary in three parts. Part I covers sections I through III.S (except for Section G: Medicare Shared Savings Program Requirements) and the Regulatory Impact Analysis. Part II will cover the Medicare Shared Savings Program Requirements. Part III will cover the updates to the Quality Payment Program. Part I includes payment policies under the PFS, including implementation of the evaluation and management (E/M) office/outpatient complexity add-on code; telehealth services; care training services, services addressing health-related social needs; dental services; and Inflation Reduction Act provisions relating to Part B drugs and biologicals. The proposed rule contains several comment solicitations, including strategies for implementing updates to indirect practice expense; reforming the process for establishing values for E/M visits and other services; and the use of digital therapeutics in clinical practice.
