Thank you for your question regarding CMS155v14 (2026 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 nutrition counseling, you will need EHR documentation of interventions performed using any codes from the "Counseling for Nutrition" (2.16.840.1.113883.3.464.1003.195.12.1003) value set. Similarly, for height, weight, and body mass index (BMI) percentile, you will need EHR documentation of the physical exam performed using any codes from the "BMI percentile"(2.16.840.1.113883.3.464.1003.121.12.1012), "Height" (2.16.840.1.113883.3.464.1003.121.12.1014), and "Weight" (2.16.840.1.113883.3.464.1003.121.12.1015) value sets. Clinically equivalent services may be mapped to the codes in the value set. If mapping is done, you should maintain documentation in case of a CMS audit.
