If you are on Medicare and managing diabetes, open enrollment is one of the most useful stretches of the year, even though it can feel like a lot of fine print. This is your annual window to review your plan, make sure it still covers the CGM sensors, insulin, and pump supplies you rely on, and switch if something better fits. A little preparation now can save you real money and a lot of hassle over the coming year, and the goal of this guide is to make that preparation feel manageable rather than overwhelming.
Below is a friendly, step-by-step checklist to help you get ready, along with the questions worth asking so your coverage matches the way you actually manage your diabetes.
First Things First: Know Your Dates and Plan Types
Medicare has specific enrollment periods, and the dates matter, so the very first step is to confirm the current year's window and deadlines directly with Medicare rather than relying on memory or last year's calendar. Enrollment dates and plan details are set each year and can change, so always verify at Medicare.gov or by calling Medicare before you make decisions.
It also helps to understand which parts of Medicare touch your diabetes supplies, because they work differently:
- Part B generally covers durable medical equipment, which is the category that often includes CGMs and related supplies when you meet the coverage criteria.
- Part D is prescription drug coverage, which typically handles insulin and some diabetes medications.
- Medicare Advantage (Part C) plans bundle coverage together and vary widely, so their diabetes benefits, networks, and costs differ from plan to plan.
Because CGMs, pump supplies, and insulin can fall under different parts depending on your situation and equipment, it is worth understanding how your specific supplies are covered before you compare plans. A supplier experienced with Medicare, like AdaptHealth Diabetes, can help you understand how your CGM and pump supplies are typically billed, which makes plan comparisons much clearer.
Your Pre-Enrollment Checklist
Walking in prepared turns open enrollment from a stressful scramble into a quick, confident review. Here is a practical checklist to work through before you compare or renew:
- List everything you use. Write down your exact supplies, including your CGM sensors and reader, insulin types and doses, pump and infusion sets or pods, and test strips if you use them.
- Review last year's costs. Gather what you actually paid out of pocket, so you can spot where a different plan might save money.
- Check your current plan's changes. Plans send an annual notice describing what is changing for the coming year. Read it for shifts in covered supplies, costs, or pharmacy and supplier networks.
- Confirm your suppliers and pharmacies are in network for any plan you are considering, since an out-of-network supplier can raise your costs significantly.
- Note any prior authorization or documentation requirements, because CGMs and pumps often need specific paperwork from your doctor to be covered.
Having this information in one place makes any conversation, whether with Medicare, a plan representative, or your supplier, far more productive. It also helps you avoid the common surprise of discovering mid-year that a favorite sensor or pump supply is no longer covered the way it was.

Questions Worth Asking Before You Choose
Once you know what you use and what you paid, a handful of targeted questions will tell you whether a plan truly fits. You do not need to be an insurance expert to ask them, and the answers make comparisons much easier:
- Are my specific CGM sensors and reader covered, and under which part? Coverage can differ between brands and between the sensor and the reader.
- Is my insulin on the plan's formulary, and at what cost? Formularies change yearly, and insulin cost protections can vary by plan.
- Are my pump and its supplies, like infusion sets, reservoirs, or pods, covered? These are often billed separately from the pump itself.
- Which suppliers and pharmacies are in network? Confirm the ones you want to use are included.
- What documentation or prior authorization will I need? Knowing this ahead of time prevents delays in getting supplies.
It is completely normal to need help sorting through this, and you do not have to do it alone. Medicare offers free counseling through the State Health Insurance Assistance Program (SHIP), your doctor's office can help with required documentation, and an experienced diabetes supplier can explain how your specific Abbott or Medtronic MiniMed supplies are usually covered.
Why It Matters
Taking time during open enrollment protects both your budget and your access to the tools that keep you healthy. The right plan means fewer surprise costs, no unexpected gaps in your sensors or insulin, and less time spent fighting paperwork during the year. For many people, a focused hour or two of preparation translates into real savings and genuine peace of mind, and that is time very well spent.

Frequently Asked Questions About Medicare and Diabetes Supplies
When is Medicare open enrollment, and can I really switch plans then?
Medicare has specific enrollment periods each year, and the exact dates are set annually, so the most reliable step is to confirm the current window directly at Medicare.gov or by calling Medicare. During the applicable period, you generally can review and change your coverage, such as switching plans or adjusting drug coverage. Because the rules and dates can change from year to year, always verify the current details rather than assuming they match a previous year.
Does Medicare cover CGMs and insulin pumps?
Medicare does provide coverage for CGMs and insulin pumps for many people who meet the applicable criteria, often under the durable medical equipment benefit, though the specific requirements and paperwork matter. Coverage can depend on your diagnosis, your treatment, and proper documentation from your doctor. Because criteria are set by Medicare and can be updated, the best approach is to confirm your eligibility and requirements with Medicare and a knowledgeable supplier who can walk you through what is needed.
Why do my CGM sensor and reader sometimes seem to be covered differently?
This is a common point of confusion. Depending on your situation and equipment, different components can be billed in different ways, and a sensor and its reader may not always be handled identically. This is exactly why listing your exact supplies and asking specific coverage questions during enrollment is so helpful. A supplier experienced with Medicare billing can explain how your particular sensors and reader are typically covered so there are no surprises.
What should I do if a supply I use is no longer covered next year?
First, do not panic, and do not stop using needed supplies without a plan. Your annual plan notice will flag changes, so review it early. If something you rely on is changing, you may have options, such as switching plans during open enrollment, asking your doctor about covered alternatives, or working with a supplier to find the best path. Reaching out well before your current supply runs low gives you time to sort it out calmly.
Where can I get free help understanding my Medicare options?
You have several free resources. Medicare itself offers information at Medicare.gov and by phone, and the State Health Insurance Assistance Program (SHIP) provides free, unbiased counseling in every state. Your doctor's office can help with the documentation that CGMs and pumps often require, and an experienced diabetes supplier can explain how your specific supplies are usually covered. Using these resources together makes the whole process far less daunting.
Prepare With a Supplier Who Knows Diabetes Coverage
Open enrollment is much easier when you have a partner who understands both diabetes supplies and insurance. AdaptHealth Diabetes can help you understand how your CGM sensors, readers, insulin pump, and related supplies are typically covered, so you can review your plan with confidence and avoid gaps in the year ahead. Reach out through our contact page or explore our resources page to get organized before enrollment.
