Medigap Plan D is one of 10 Medicare Supplement Insurance plans that cover certain out-of-pocket expenses for people with Original Medicare (Part A and Part B). Plan D covers more than most Medigap plans, but not as much as Medigap Plan F or Plan G.
How it works
After Medicare pays its approved amount for services, Medigap plans help cover what would otherwise be your out-of-pocket costs: copayments, coinsurance and some deductibles. These plans are available only to individuals enrolled in Medicare Part A and/or Part B — not to Medicare Advantage members.
There are 10 standardized Medigap plans available in most states (except Massachusetts, Minnesota and Wisconsin, which use different standards). The plans differ in terms of coverage for services, out-of-pocket limits and premium costs.

What Medigap Plan D covers

What Medigap Plan D doesn’t cover
Medigap Plan D covers more than most Medigap plans, but it’s not the most comprehensive option. For example, Plan D doesn’t cover Medicare Part B excess charges (if a provider is permitted to charge more than Medicare’s approved amount and does so). Medigap Plan G is an option to consider if you want excess charge coverage on top of everything included in Plan D.
Additionally, all Medigap plans, including Plan D, sold to new Medicare members don’t cover the following:
- Part B deductible (since 2020, new Medicare members can’t buy any plan that covers the Part B deductible, although existing members may own older plans that do).
- Prescription drugs (that's Medicare Part D).
- Long-term care (like non-skilled care you get in a nursing home).
- Private-duty nursing.

How much does Medigap Plan D cost?
Medigap Plan D is regulated by the government but sold by private health insurance companies. Prices vary according to factors including age, location and tobacco use.
In Atlanta, a metro area with average costs for Medigap policies, monthly Plan D premiums for a 65-year-old female nonsmoker range from $158 to $386.
🤓 Nerdy Tip
A $158 Medigap Plan D policy has the same standardized Medicare coverage as one that costs $386. Companies may add on extra perks like discounted gym memberships, but the core Medicare benefits are the same, so go ahead and compare based on price. To get the best price for Medigap Plan D coverage, enroll during your Medigap open enrollment period.
This period happens only once. It starts once you’re 65 and enrolled in Medicare Part B, and lasts for six months. (If you're still working after 65 and covered by a group employer plan that is deemed creditable coverage, your six-month period starts after you’ve ended active employment or no longer have that insurance.)
Medigap policies are cheapest and easiest to get during this open enrollment period because insurance companies aren’t allowed to factor your health or medical history into your price. After the period ends, the prices may go up or you may be denied coverage due to your health status or medical history.
In some states, insurance companies sell Medigap plans to those under 65 who are living with a disability and are eligible for Medicare. You can find more information through your State Health Insurance Assistance Program, or SHIP.
