Best Medicare Supplement Plans for Diabetes
According to the Centers for Disease Control and Prevention, an estimated 40.1 million Americans have diabetes, and unfortunately, the cost of the illness is high.1 Medical expenditures for people with diabetes average $12,022 per year, a study published in the journal Diabetes Care found. The same research concluded that people with diabetes have medical costs 2.6 times higher than those who don't.2 Diabetes can cause blood circulation problems over time that elevate risk levels for cardiovascular issues, strokes, and other diseases.
Good health care can help those with diabetes manage the disease and prevent complications. Medicare Parts A, B, and D cover basic treatment such as anti-diabetic drugs; however, because diabetes is such a complex disease, the plans may not cover everything. Supplemental Medicare, or Medigap, plans are designed to help fill in the gaps.

Unfortunately, Anthem is only available in certain states, and their range of plans is somewhat limited when compared to the other providers on this list.

How Medicare Covers Diabetes Treatments
People with diabetes will need anti-diabetic drugs to manage blood sugar and equipment to monitor their blood sugar. Adults will also need to see the doctor regularly to manage their condition and may need extra treatment if they have diabetic peripheral neuropathy in their feet.
Medicare Part B and D cover blood glucose testing, medical and educational services, and diabetes medication. Often, the patient covers a 20 percent coinsurance for doctor's visits or medication. Copayments, coinsurance, and deductibles for treatment can add up. Additionally, Medicare Part B does not cover insulin and the supplies necessary to administer it (unless used with an insulin pump), although Part D now caps insulin costs at $35 per month.7 Medicare Part B covers up to a certain amount of insulin test strips and lancets every few months. It also covers some preventative care like screenings for heart disease, glaucoma tests, and nutritional counseling.
These gap plans are especially beneficial, as people with diabetes face significantly higher out-of-pocket costs for care and prescriptions compared to those without the condition. By purchasing Medicare supplemental insurance, you'll have greater peace of mind when it comes to managing your out-of-pocket expenses.
Did You Know? Medicare covers Ozempic for the treatment of Type 2 diabetes under most Medicare Part D plans.
Which Medigap Plans Are Ideal for Diabetes?
Medicare Part B covers most diabetes medication and treatment, so if you're looking for supplemental insurance, you should choose a plan that covers the deductible, coinsurance, and copayment for Part B plans. For that reason, we recommend Medigap Plan G for comprehensive diabetes coverage, as Plan F has not been available to new Medicare beneficiaries since 2020.
Pro Tip: Wisconsin, Minnesota, and Massachusetts have different Medigap plans than the rest of the country, so be sure to contact a provider directly if you live in one of these states.
For example, a client of mine spends $2,000 per month for diabetes management and care. Medicare only covers $1,600 of the total monthly costs. He ended up finding a Medigap plan that covered the balance, so he no longer has out-of-pocket costs for medication or visits.
How We Chose the Best Medigap for Diabetes
Because Medigap plans are federally regulated, a Plan G from one company will offer the same coverage as that of another company. With this in mind, we looked for the following when it came to choosing the best Medigap policies for diabetes:
- Affordable premiums: Those with diabetes already have their hands full when it comes to paying for health care. Because of this, we looked for providers that offered affordable monthly premiums, lessening your load.
- Diabetes-specific benefits: While the actual coverage of Medigap policies will be the same across providers, some insurers offer additional health and membership benefits that are particularly useful to those with diabetes.
- Simple management: Anyone who has ever navigated the world of U.S. health care knows how complicated it can be. Because of this, we looked for providers that simplified the process of obtaining and managing coverage. All of the providers on this list offered stellar customer service, demystifying what could otherwise be a difficult circumstance.
Frequently Asked Questions
-
Does Medicare cover diabetes treatment and supplies?
Yes, Medicare Parts B and D cover diabetes treatment, including anti-diabetic drugs, blood glucose testing, medical services, and educational programs. However, Medicare Part B doesn’t cover insulin unless it’s used with an insulin pump, and you’ll typically pay 20 percent coinsurance for doctor visits and medication. Medicare also limits coverage for test strips and lancets, which is why many people with diabetes choose Medigap plans to cover these gaps.
-
What's the best Medigap plan for someone with diabetes?
Medigap Plan G is currently the most comprehensive option for diabetes coverage because it covers Part B coinsurance, copayments, and most out-of-pocket costs. Since people with diabetes generally pay higher out-of-pocket costs for care and significantly more for prescriptions, this comprehensive plan provides strong financial protection. Note that Plan F (which also covers the Part B deductible) is only available to those who became Medicare-eligible before January 1, 2020, but Plan G remains an excellent alternative for newer beneficiaries.
-
How much do Medicare supplement plans for diabetes cost?
Monthly premiums for Medigap plans typically range from $100 to $400 or more, depending on your age, location, and chosen plan. For example, Plan G premiums for a 65-year-old can start around $100 to $200 per month, while premiums for older enrollees may be higher across different providers and states. While these premiums may seem high, they can help reduce the substantial out-of-pocket diabetes costs that Medicare doesn’t cover, potentially saving you money overall.
-
Can I switch Medigap plans if my diabetes care needs change?
Yes, you can switch Medigap plans, though it may be easier during certain periods. During your Medigap Open Enrollment Period (the six months after you turn 65 and enroll in Medicare Part B), insurance companies can’t deny you coverage or charge more due to pre-existing conditions like diabetes. Outside this period, switching plans may be more difficult as insurers can consider your health status. Your coverage will remain the same if you move to a different state.
-
Do any Medigap providers offer special programs for diabetes management?
Yes, several providers offer diabetes-specific benefits beyond standard Medigap coverage. Some insurers provide wellness programs that include diabetes education resources and care coordination services. Additionally, many carriers offer 24/7 nurse hotlines where you can get healthcare advice about managing your condition. While specific program offerings vary by provider and location, these extra benefits can make managing diabetes easier and more affordable. Contact individual insurers directly to learn about their current diabetes-related programs.
