Summary
Connecticut Medicaid updated billing guidelines for Continuous Glucose Monitors (CGM), changing the reimbursement methodology for FreeStyle Libre systems under code K0553 and clarifying that certain supply codes cannot be billed separately when K0553 is used. DME providers must now match claims to actual shipments and cannot bill until all items are delivered to the patient.
Action Required
Effective March 2, 2022: DME providers billing Connecticut Medicaid must update billing practices for CGM systems - stop billing codes A4233-A4259, E0607, and E2101 separately when using K0553, match claims exactly to shipment amounts rather than uniform monthly billing, and ensure date of service reflects the last delivery date when all items are received by patient. Update billing system to prevent separate billing of bundled supply codes.
