What is Medicare Supplement Plan D?

Not to be confused with Medicare Part D, which covers prescription drugs

Plan D is one of the 10 standardized Medicare Supplement plan options available for purchase in most states. Not to be confused with Medicare Part D, which offer prescription drug plans (PDP).

The goal of Medicare Supplement (Medigap) insurance is to fill in some of the out-of-pocket costs left over after Original Medicare (Parts A & B) coverage. (For reference, ‘Medigap’ is another term often used for Medicare Supplement. We will use them interchangeably.)

The 10 standardized plans cover varying degrees of your Original Medicare deductibles, copays, and coinsurance. Medicare Supplement plans are labeled: A, B, C, D, F, high deductible F, G, high deductible G, K, L, M, N.

(Be careful not to confuse Medigap plans A, B, C and D with Medicare Parts A, B, C and D. They are different.)

Medigap plans are not connected with or endorsed by the U.S. government or the federal Medicare program. Like all Medigap plans, Plan D will have the same benefits no matter which insurance carrier you buy your policy from. The only difference between a Plan D from Humana, a Plan D from Aetna, a Plan D from UnitedHealthcare AARP, or a Plan D from any other insurance carrier will be the price.

Medicare Supplement Plan D Popularity

Medicare Supplement Plan D is not particularly popular, but it is a great fit for certain individuals.

Coinsurance is the amount left over after the 80% covered by Original Medicare

Medicare Supplement Plan D does not cover

Why else you might want a Medicare Supplement policy

Medicare Supplement Plan D is just one of the Medigap plans available. It’s important to compare Medigap plans and choose the option that’s best for your healthcare needs (now and down the road) and your budget.

Anyone who has Original Medicare is eligible to buy a Medigap plan. You cannot however buy a Medigap plan if you have a Medicare Advantage plan.

Beneficiaries who went without a Medicare Supplement plan spent an average of $5,374 on out-of-pocket costs in 2016, according to a study by the Commonwealth Fund, more than twice what those with a Supplement plan spent.

The best time to purchase a Medicare Supplement plan is during your personal initial enrollment period. Initial enrollment period is the first six months after you’re both 65 years old and enrolled in Medicare Part B. The typical enrollee will coordinate their Medigap policy to begin on the month they turn 65.

You can still buy a Plan D later, but you may have to go through medical underwriting. Underwriting could mean higher premiums or having a pre-existing condition not covered.

Medicare Advantage

You cannot have a Medicare Supplement Plan D with Medicare Advantage.

Medicare Advantage (Part C) is a private alternative to replace Original Medicare (Parts A & B) and typically offers additional benefits. Medicare Advantage plans often limit your coverage to a particular network of healthcare providers. Plans that allow you to see out-of-network providers typically charge you more.

You must be enrolled in Medicare Parts A and Part B to be eligible to apply for a Medicare Advantage plan.

You may pay a premium for your Medicare Advantage plan, in addition to your Part B premium. To be clear, you will still need to pay your Part B premium.
