Medigap Plan M is a deductible-sharing Medicare Supplement policy that provides a lower premium in exchange for fewer benefits. Plan M is a deductible sharing or cost-sharing plan. If you’re comfortable with paying more out-of-pocket medical costs, Plan M might be right for you.

Medicare Supplement Plan M Coverage

Medigap Plan M will cover the Part A hospital coinsurance, Part A hospice coinsurance, Part B coinsurance, Part B preventive care coinsurance, and 50% of the Part A deductible.

Medicare Supplement Plan M covers the first 3 pints of blood each year, skilled nursing facility care, and foreign travel emergency.

What is Deductible Sharing Plan M?

Medigap Plan M leaves you responsible for paying 50% of your Part A deductible. Since you pay a portion of this deductible, we call Plan M a deductible-sharing plan. Other cost-sharing Medicare Supplement plans include Plan K and Plan L.

What Does Medigap Plan M Not Cover?

Medicare Plan M won’t cover the Part B deductible or excess charges. Like other Medigap plans, Plan M won’t cover dental, vision, Part D prescriptions, long-term care, or private nursing. You can purchase a separate policy covering dental, vision, and Part D drugs.

Who Can Benefit from Medicare Plan M?

You could benefit from Medigap Plan M if you need a lower monthly premium and don’t mind paying 50% of your Part A deductible.

Plan M can be beneficial, but it’s worth comparing Plan N and Plan G to Plan M before you make your final decision. An insurance agent can help you determine which policy will be most beneficial for you.

How Much Does Medigap Plan M Cost?

Medigap Plan M costs on average, between $130 to $210 monthly. The cost of Medigap can vary depending on location, age, tobacco use, gender, and eligibility. The premium for Plan M is likely lower than most other plans since your out-of-pocket costs are higher. Contact an insurance agent to compare rates in your area for the most accurate quote on Plan M.


Is Medicare Plan M Better Than Plan N?

Some beneficiaries may find that Plan N makes more sense and covers the Part A deductible 100%. Comparing the premiums in your area is important.

If Plan N has a lower premium, that plan may seem more appealing. Now, if Plan M has a lower premium, you may decide the portion of the Part A deductible is no big deal.

However, if Plan G has competitive premiums in your area, you may decide to pay more and have more coverage in exchange for fewer out-of-pocket costs.

When Can I Enroll in Medigap Plan M?

Just like with any Medicare Supplement policy, you can enroll anytime if you have Part A and B. You can’t have a Medicare Advantage plan AND a Medigap plan; you must only choose one.
