The Centers for Medicare and Medicaid Services (CMS) released the 2023 Medicare Physician Fee Schedule (MPFS) and Hospital Outpatient Prospective Payment System (HOPPS) final rules, with cuts of 4% to radiation oncology due to reductions to the conversion factor and the second year of the clinical labor price update, which shifts resources from specialties to primary care services. Additionally, CMS notes in the MPFS that it is reviewing the current payment policy related to the conventional treatment delivery, IMRT and IGRT “G” codes, which could result in additional payment cuts in future rulemaking. ASTRO remains concerned that the continued payment cuts to radiation therapy services will impact access to care close to home. ASTRO and aligned stakeholders are actively lobbying Congress to address planned payment cuts by year-end. Please review the 2023 MPFS Final Rule Summary and the 2023 HOPPS Final Rule Summary
