4 9403925-011 20101014 “ Continuous glucose monitoring (CGM) technology is not only novel, but it can improve the lives of patients who incorporate it into a comprehensive diabetes management plan. ” -- AACE Consensus Statement on CGM 2010

7 9403925-011 20101014 AACE Reviews Clinical Evidence on CGM Professional CGMPersonal CGM Can reduce A1C in adult and pediatric patients with type 1 diabetes and A1C > 7.0%, without increasing hypoglycemia in adult and pediatric patients 6,7 In adults and adolescents, more consistent use predicts successful A1C reductions 7 Can reduce hypoglycemia in well-controlled adult and youth patients (A1C<7.0%) with type 1 diabetes, without increasing A1C 8 Can identify undetected hyperglycemia in pregnant women – Professional CGM identified 94-390 minutes/day of undetected hyperglycemia in studies 1,2,3 Effective in improving maternal glycemic control, infant birth weight, and macrosomia risk in women with type 1 or type 2 diabetes 4,5 1 Jovanovic L.

8 9403925-011 20101014 AACE Supports Broad Range of Ideal Candidates for CGM Patient selection and usage: Patients with type 1 or type 2 diabetes who: are not at their A1C target. have recurrent hypoglycemia or hypo unawareness. All pregnant women with type 1 diabetes. CGM may also facilitate treatment adherence for women with type 2 diabetes or insulin-requiring gestational diabetes. Intermittent use may be useful for youth with type 1 diabetes who are changing their diabetes regimen or are experiencing nocturnal hypo, dawn phenomenon, hypo unawareness, or post-prandial hyperglycemia. Recommended to use Professional CGM on an episodic basis. Professional CGM

9 9403925-011 20101014 AACE Supports Broad Range of Ideal Candidates for CGM Patients with type 1 diabetes with: Hypoglycemia unawareness or frequent hypoglycemia. A1C above target or with excess glucose variability. Requires lowering A1C without increased hypoglycemia. During preconception and pregnancy. Children and adolescents who have met A1C targets (<7.0%) and who may be highly motivated. Youth with A1C levels ≥7.0% and are able to use the device on a near-daily basis. The following might be good candidates and a trial period of 2-4 weeks is recommended: Youth who frequently monitor their blood glucose levels. Committed families of young children (younger than 8 years) especially if the patient is having problems with hypoglycemia. Personal CGM

10 9403925-011 20101014 AACE Explains the CPT Codes Available for CGM Covers sensor placement, hook-up, calibration of monitor, patient training, removal of sensor and printout of report. Modifier (-25) must be appended to the evaluation and management code if this code is billed with code 95250. Professional CGM can be billed on either the day the device is inserted and monitoring is initiated, or when the sensor is removed. Personal CGM can be billed at first patient training and subsequently when data is downloaded. CPT Code 95250: Data Collection Does not have to take place in the context of a face-to-face meeting. If billed at a time separate from another evaluation and management service such as an office visit, no additional modifier is needed. CPT Code 95251: Data Interpretation *Neither code can be billed more than every 30 days.

11 9403925-011 20101014 AACE Provides Status of CGM Reimbursement Both codes 95250 and 95251 cannot be billed more than every 30 days. Many large, private US health plans provide coverage for both Personal and Professional CGM, especially for patients with type 1 diabetes and those with severe hypoglycemia. The U.S. Centers for Medicare and Medicaid Services presently only have reimbursement for Professional CGM. “ With diligent administrative management and follow-up, it is possible to achieve good coverage for Professional CGM. ”

12 9403925-011 20101014 AACE Provides Guidance on Clinic Implementation Professional CGMPersonal CGM Patient follow-up requirements and resources Technology requirements and staff responsibilities for office implementation Minimal patient training an set-up time requirements “ Consider selecting a dedicated practice champion to manage the process and equipment ” “ Offices should be proactive in arranging patient follow-up for data interpretation ” “ Only a few companies have successfully developed intuitive software for downloading CGM results. However, patients and endos find this helpful, if not critical. ”

13 9403925-011 20101014 Reference: Current FDA-Approved Labeling on Medtronic CGM Devices Continuous glucose monitoring systems are limited to sale by or on the order of a physician and should only be used under the direction of a healthcare professional familiar with the risks associated with the use of these systems. Continuous glucose monitoring systems are intended for monitoring interstitial glucose levels in persons with diabetes. These systems provide information regarding potential high and low glucose levels and can provide an indication of when patients should obtain a glucose reading using a home glucose meter. The information provided by continuous glucose monitoring systems is intended to supplement, not replace, readings from a home glucose meter. Patients should always confirm glucose level information provided by a continuous glucose monitoring system before making adjustments to diabetes therapy. Insertion of a glucose sensor may cause bleeding or irritation at the insertion site. Consult a physician immediately if you experience significant pain or if you suspect that the site is infected.
