Continuous Glucose Monitoring in Primary Care: A Practical, Multidisciplinary Review of Data Interpretation and Billing Updates.

Abstract

Continuous glucose monitoring (CGM) offers real-time and longitudinal insights into glycemic patterns, time in range, and hypoglycemia. Adopting CGMs into practice can improve clinical outcomes while strengthening patient engagement and enabling data-driven care across routine visits and population health programs. Despite strong evidence of benefit, CGM remains underused in primary care, where most patients with diabetes mellitus are managed. Barriers include limited familiarity with CGM technology, interpretation, workflow, documentation and billing, and patient access and education. The purpose of this clinical review was to help equip primary care clinicians with a concise, family medicine-focused framework for adopting CGM, including technology overview, patient selection and education, practical interpretation of standardized reports, team-based workflow, documentation, and reimbursement.
