In January 2017, the Centers for Medicare & Medicaid Services (CMS) approved payment for a new G-code, G0505, which describes assessment and care plan services for patients with cognitive impairment. This code will likely be converted to a permanent CPT code, approved by the CPT Editorial Panel, in 2018.
Code definition: Cognition and functional assessment using standardized instruments with development of a recorded care plan for the patient with cognitive impairment, history obtained from patient and/or caregiver, in office or other outpatient setting, home, domiciliary or rest home.
Performing providers: G0505 represents a service that can only be performed by a physician or qualified non-physician practitioner (nurse practitioner or physician assistant).
