As of Dec. 1, 2024, if you had not already filled a prescription for a glucagon-like peptide (GLP-1) medication using mail order through HealthSelect℠ Medicare Rx, you will not be able to fill a new GLP-1 prescription through mail order. You can fill a new prescription for a GLP-1 medication at your local retail pharmacy. Remaining refills on your active mail-order prescriptions for GLP-1s made before Dec. 1, 2024, can still be filled by mail.
