Summary & Overview
CPT 95249: Professional Continuous Glucose Monitoring, Patient‑Supplied Device
Headline: CPT code 95249: Professional continuous glucose monitoring service for patient‑supplied equipment
Lead: CPT code 95249 captures a professional continuous glucose monitoring (CGM) encounter in which the provider performs sensor placement, hook‑up, calibration, patient training, removal, and generates the recording printout for at least 72 hours when the patient supplies the device. The code standardizes reporting for CGM services where the device is not furnished by the clinician or facility.
Why it matters: As CGM use expands for diabetes management, consistent coding of professional monitoring encounters is critical for care coordination, quality measurement, and claims processing. CPT code 95249 ensures a clear distinction between clinician‑provided device services and those using patient‑owned equipment.
Key payers covered: This analysis addresses national payer practices for Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: The publication provides benchmarks and utilization context for CPT code 95249, outlines common clinical settings and operational workflows tied to the code, and summarizes payer coverage patterns and coding considerations. It also highlights documentation elements tied to the included activities (placement, calibration, training, removal, and printout) and notes where input data is not available. Data not available in the input.
Billing Code Overview
CPT code 95249 describes monitoring of interstitial glucose levels using subcutaneously implanted sensors for a minimum of 72 hours when the patient provides the equipment. The service includes sensor placement, hook‑up, monitor calibration, patient training, sensor removal, and the recording printout.
Service type: Continuous glucose monitoring (professional) with patient‑supplied equipment
Typical site of service: Outpatient clinic or ambulatory care setting, including endocrinology or diabetes specialty clinics, and other outpatient settings where professional device setup, calibration, training, and removal can be provided.
Clinical & Coding Specifications
Clinical Context
A 48-year-old patient with type 1 diabetes presents for ambulatory continuous glucose monitoring (CGM) to assess glycemic patterns and guide therapy adjustments. The patient provides their own FDA-cleared subcutaneous sensor and compatible reader or smartphone. The clinical workflow includes a pre-procedure encounter where indication and consent are confirmed, sensor placement by a trained clinician or diabetes educator, hook-up and monitor calibration per manufacturer instructions, brief patient training on device alarms and sensor care, monitoring of interstitial glucose levels for a minimum of 72 hours, sensor removal at the end of the wear period, and generation of a printout or electronic report for review. The provider documents sensor placement, calibration steps, patient education, duration of monitoring, any troubleshooting or adverse events, and interpretation of the glucose record during a follow-up visit or as part of the same encounter when review and interpretation are performed.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable E/M service by the same physician on the same day | Use when a distinct evaluation and management visit is provided in addition to the CGM service on the same day. |
