Summary & Overview
CPT 95251: Professional Interpretation and Report of CGM Data
CPT code 95251 denotes the professional component of continuous glucose monitor (CGM) care: a clinician analyzes CGM data and produces a written interpretation. This code matters nationally as CGM use grows for diabetes management and payers refine coverage and payment policies for remote monitoring and data-driven diabetes care. Claims for 95251 capture physician or qualified health professional time spent interpreting device data rather than device supply or technical download functions.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on coding intent, common sites of service, and the professional nature of the service. The publication also summarizes payer coverage patterns and benchmarks where available, highlights policy updates affecting professional CGM interpretation, and provides clinical context about how interpretation supports diabetes management.
This summary is intended for clinicians, billing professionals, and policy analysts seeking a quick, national-level reference on billing for professional CGM interpretation services. Data not available in the input will be noted where applicable in detailed sections.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with type 1 or type 2 diabetes managed with insulin who uses a continuous glucose monitor (CGM). The patient wears a CGM sensor for a period (typically 7–14 days) and the device collects interstitial glucose readings. A licensed clinician (endocrinologist, diabetes specialist, or primary care provider with diabetes management responsibility) downloads the CGM data, analyzes time-in-range metrics, glycemic variability, hypoglycemia and hyperglycemia patterns, and documents an interpretation and treatment recommendations in a formal report. The service is performed as the professional interpretation component after data collection and is not the technical/upload component. Typical workflow: device data upload by patient or clinic staff → data review by clinical provider → structured interpretive report generated (including ambulatory glucose profile, trend analysis, and actionable interpretation) → documentation placed in the medical record and communicated to the patient. This professional-only service is commonly billed when the provider reviews >72 hours of CGM data and issues an interpretation report, independent of a separate office visit.
