What 95251 covers
This service is the clinician's evaluation of at least 72 hours of interstitial glucose readings recorded by a subcutaneous sensor. A physician, nurse practitioner, or physician assistant reviews a downloaded or remotely uploaded ambulatory glucose profile from a Dexcom, FreeStyle Libre, or similar system. The practitioner assesses time in range, low and high glucose excursions, overnight and postprandial patterns, and variability, then writes patient-specific findings and recommendations such as insulin dose or timing changes. Endocrinology and primary care practices perform these reviews for patients with type 1 or insulin-treated type 2 diabetes.
Report 95251 no more than once per month for a monitoring period of at least 72 hours, even if data are reviewed multiple times. Document the monitoring dates and a signed interpretation; a device printout without clinical analysis is insufficient. CMS classifies 95251 as professional-component-only, covering analysis, interpretation, and report; do not append modifier 26. When performed, patient-owned CGM startup and training are described by 95249, while 95250 describes setup and recording using practice-provided equipment. Neither technical service is required for 95251 when a patient's existing device provides the data.

95251 billing questions
Can 95251 be billed on the same day as an office visit?
Yes. The CGM interpretation can be reported with a separately documented E/M service on the same date. The time and work spent interpreting the CGM data should not also be counted toward the E/M level.
Does 95251 require a face-to-face encounter?
No. The interpretation can be performed from data the patient uploads to a cloud platform or brings to the office. The billable work is the analysis and written report, not a visit.
How often can 95251 be reported?
Report it no more than once per month, regardless of how many times the data are reviewed during that month. The interpretation requires at least 72 hours of monitoring.
Should modifier 26 be appended to 95251?
No. The code already represents the professional interpretation and report. When performed, patient-owned CGM startup and training are described by 95249; setup and recording with practice-provided equipment are described by 95250.
Is 95251 billable when the patient uses their own personal CGM?
Yes. Interpretation of data from a patient-owned device is reported with 95251. Report 95249 only if the practice also performed the startup, hookup, and training for that device.
What documentation supports 95251?
The record should show monitoring dates covering at least 72 hours and a patient-specific interpretation of glucose patterns. It should also document the clinician's recommendations or management changes and the interpreting practitioner's signature.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
