If a physician or mid-level practitioner is interpreting personal or professional use CGM data they would bill under CPT code 95251. Services associated with CPT code 95251 may be a non-face-to-face service.

CPT code 95250 (for Professional CGM only) is paid under Ambulatory Procedure Classification (APC) 5012 with 2017 national average payment of $106.
