CGMs don’t work in a vacuum — they’re one piece of a medication and management picture that gets complicated fast, especially after 65. I’m not a clinician, but I’ve sat close enough to the clinical side of DME for a long time to know the questions seniors should be asking their doctors and often aren’t.
Understanding Medicare coverage for diabetes medications can feel overwhelming, especially with changes coming in 2026. This comprehensive guide breaks down exactly what Medicare will cover for diabetes medications, how to access your benefits, and what you can expect to pay.
