Medigap Plan M is one of the standardized Medicare Supplement Insurance plans available to individuals enrolled in Original Medicare (Part A and Part B).
Designed to help cover out-of-pocket costs that Original Medicare doesn’t pay—like copayments, coinsurance, and deductibles—Plan M offers a balance of coverage and affordability that may appeal to certain Medicare enrollees.
What Does Medigap Plan M Cover?
Medigap Plan M provides coverage for most of the major out-of-pocket costs associated with Original Medicare. Here's a breakdown of its coverage:
Basic Benefits:
- Medicare Part A Coinsurance and Hospital Costs
- Medicare Part B Coinsurance or Copayment
- First 3 Pints of Blood
- Part A Hospice Care Coinsurance or Copayment
- Skilled Nursing Facility Care Coinsurance
- Medicare Part A Deductible (50%)
- Foreign Travel Emergency (80%)
Unlike other Medigap plans like Plan G or Plan F, Plan M only covers 50% of the Medicare Part A deductible, which is a key cost-sharing difference. This allows insurers to offer lower premiums in exchange for a bit more out-of-pocket responsibility.
In 2025, the Medicare Part A deductible is $1,676, which means with Plan M you would be responsible for $838.
How Does Plan M Compare to Other Medigap Plans?
All Medigap plans are standardized by the government, which means each individual plan offers the same benefits across the Country, regardless of where you live or which carrier you choose.
When comparing Plan M to other Medigap plans, the biggest difference is the Part A deductible coverage. Plan M covers 50% of the Part A annual deductible, while other plans such as Plan N or Plan G cover 100% of the Part A deductible.
Along with this Plan M does not cover Part B Excess Charges, while Plan G does cover Part B Excess Charges.
How Much Does Medicare Supplement Plan M Cost?
Medigap Plan M costs will depend on your location, age, sex, health status, and when you buy but it is generally considered a middle ground plan in terms of monthly premiums, so it may be a lower monthly cost compared to more all encompassing Medigap plans.
Although you should compare Monthly Premiums compared to the coverage offered, because it might make sense to chose a more encompassing plan.
Is Medicare Supplement Plan M Available in All States?
Although all Medigap plans are standardized by the Government, so each plan's coverage and benefits stay consistent, this doesn't guarantee that Plan M is available in your area. Coverage availability will depend on which carriers are available in your area.
