Thank you for your question regarding CMS155v13 (2025 Performance Period). The intent of this measure is to identify encounters performed by primary care providers (PCPs) or obstetrician/gynecologists (OB/GYNs) in the Initial Population. However, the denominator encounter logic and codes are not provider specific. As specified in the measure logic, visits that qualify for the Initial Population are those encoded with any of the codes listed in the value sets under the “Qualifying Encounters” definition. As of now, providers can decide which measures they want to report and need to apply the necessary restrictions at the individual provider level. For questions around reporting requirements, please review the QPP website or contact the QPP Helpdesk at QPP@cms.hhs.gov .
