Currently, most insurance companies consider CGM a medical necessity for patients who have type 1 diabetes, have completed a detailed education program about managing this chronic illness, need multiple insulin injections or frequent adjustments to insulin pump dosage each day, test their own blood glucose at least four times a day and have frequent episodes of hypoglycemia.
According to the Endocrine Society, the ideal CGM group for optimal outcomes includes adults who have type 1 diabetes, can use the device as directed, and have A1C levels higher than 7%. The organization also cites CGM as appropriate for people who require intensive insulin therapy for diabetes care, who experience hypoglycemia overnight, or who have difficulty recognizing the signs of hypoglycemia. Doctors can prescribe certain continuous glucose monitors for children ages 2 and older with type 1 diabetes.
