How Often Will Medicare Replace My CGM? Your Complete Reorder Guide

This article provides general information about CGM supply reordering. Always consult your healthcare provider and check your specific Medicare plan coverage details.

Managing your CGM supply reorder schedule doesn’t have to be complicated. As a Medicare senior with diabetes, keeping track of when to order new CGM supplies is essential for maintaining consistent glucose monitoring. Let’s break down exactly when and how to reorder your supplies, so you never run out.

Your Continuous Glucose Monitor (CGM) requires regular replacement of certain parts:

• Sensors (typically changed every 10-14 days)
• Transmitters (usually replaced every 90 days)
• Receiver (if applicable, replaced every 4-5 years)

🔔 Set a reminder on your calendar or ask a family member to help you track replacement dates. Many seniors find it helpful to mark sensor change dates on their kitchen calendar. Make sure you never used expired sensors!

What You’ll Need to Replace
