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 insurance plans include Plan K and Plan L.

What does Medigap Plan M not cover?

Medicare Supplement Plan M won’t cover the Medicare Part B deductible or Part B excess charges. Like other Medigap insurance plans, Plan M won’t cover health care costs for dental, vision, Part D prescription drugs, long-term care, or private nursing. You can purchase a separate dental, vision, and Part D prescription drug coverage policy.

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 most benefit you.

How much does Medigap Plan M cost?

Medigap Plan M costs, on average, between $130 to $210 monthly. The cost of a Medicare Supplement can vary depending on location, age, tobacco use, gender, and eligibility. The premium for Medigap Supplement 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.

Medicare Supplement Plan M reviews

Medigap Plan M is most similar to Plan D. The primary difference with Plan M is that you’re responsible for 50% of the Part A deductible. This plan can save a little money for beneficiaries that don’t use the hospital often. Some states provide this plan as an option for beneficiaries that are under 65.


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 essential.

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, suppose Plan G has competitive premiums in your area. In that case, 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?

Like 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 Medicare Supplement plan; you must only choose one.

Also, the ideal time to sign up for any Medigap plan is during the Medicare Supplement Open Enrollment Period.

You’ll have Guaranteed Issue Rights during this time, meaning the insurance company can’t deny you a policy and get the best premium ratings. These “Medigap protections” allow you to get coverage without worrying about your pre-existing conditions.

What are Part B excess charges?

A Medicare Part B excess charge is a surcharge above the Medicare-approved amount. Most doctors accept Medicare assignments, so there is less than a 5% chance of running into these excess charges.
