The 2020 Medicare Physician Fee Schedule (MPFS) final rule outlines key changes affecting clinicians, including a slight increase in the non-anesthesia conversion factor and a decrease in the anesthesia conversion factor. Significant modifications to evaluation and management (E/M) codes and documentation requirements will take effect in 2021, potentially increasing payments for certain E/M services but possibly leading to cuts in other areas. Additional provisions address nurse anesthetists' scope of practice, physician assistant supervision, and the introduction of new HCPCS codes for telehealth services, alongside changes to the Merit-based Incentive Payment System (MIPS) scoring.
