Plan N covers the costs Medicare Part A and Part B don't pay

Medicare Supplement Plan N is designed to fill gaps in Original Medicare coverage. It pays your share of costs that Medicare approves but doesn't fully cover — things like copayments, coinsurance, and deductibles. Plan N does not cover services Medicare itself doesn't cover, and it does not provide prescription drug coverage.

Plan N is one of ten standardized supplement plans. The letter designation means the same benefits appear in every Plan N sold, regardless of which insurance company offers it. The price varies by insurer and location, but what the plan pays out is identical.

The main trade-off with Plan N is that it costs less per month than some other plans (like Plan G or Plan F), but it requires you to pay more out of pocket in certain situations. Understanding exactly when you pay and when the plan pays is the difference between choosing the right plan and discovering a surprise bill later.

Key Takeaways

  • Plan N pays Medicare Part A deductibles, copayments for hospital stays, and coinsurance for skilled nursing facilities, but you pay the Part B deductible yourself.
  • You pay a copayment (usually $20 for office visits, $50 for emergency room) when you see a doctor, and Plan N does not cover this cost.
  • Plan N covers excess charges when a doctor bills more than Medicare allows, but only up to the amount Medicare approves.
  • Plan N does not include prescription drug coverage; you must join a separate Part D plan to cover medications.
  • The plan covers blood transfusions, hospice care copayments, and foreign travel emergencies, but not routine dental, vision, or hearing care.

What Plan N pays for hospital and facility care

Plan N covers your Part A deductible — the amount you would normally owe before Medicare starts paying for a hospital stay. In 2024, this deductible is $1,676 per benefit period, but Plan N pays it so you do not.

During a hospital stay, Medicare covers most costs after the deductible, but you owe a daily copayment for days 61 through 90 of the same stay. Plan N pays this copayment. If you stay longer than 90 days, you have access to lifetime reserve days (60 additional days total across your lifetime), and Plan N covers the copayment for those days too.

For skilled nursing facility care (not regular nursing home care, but a facility providing medical rehabilitation after a hospital stay), you pay coinsurance starting on day 21. Plan N covers this coinsurance. Medicare covers the first 20 days fully; you owe nothing. Days 21 through 100, you owe coinsurance per day, and Plan N pays it.

What you pay when you see a doctor

Plan N does not cover the Part B deductible. In 2024, this is $240 per year. You pay this amount yourself before Medicare and Plan N start sharing costs for doctor visits and outpatient services.

After you meet the Part B deductible, Plan N covers coinsurance — Medicare's share of the cost after it pays its portion. For most doctor visits and outpatient services, Medicare pays 80% and you would normally owe 20%. Plan N pays that 20% coinsurance.

However, Plan N does not cover the copayment you owe at the time of the visit. If your doctor charges a flat copayment (for example, $20 for an office visit or $50 for an emergency room visit), you pay this directly. This is the main out-of-pocket cost difference between Plan N and more comprehensive plans.

Excess charges and what Plan N covers

Some doctors do not accept Medicare's approved amount as full payment. They bill higher, and the difference is called an excess charge. Plan N covers excess charges, but with a limit: it pays only up to the amount that Medicare says is reasonable.

For example, if Medicare approves $100 for a service and a doctor bills $120, the excess charge is $20. Plan N covers this $20. However, Plan N does not cover excess charges beyond what Medicare deems reasonable, and it does not cover charges from doctors who do not participate in Medicare at all.

This protection matters most if you see doctors frequently or have ongoing treatment. It reduces the risk of a bill larger than you expected, but it is not a blank check for any price a provider charges.

What Plan N does not cover

Plan N does not cover prescription drugs. You must join a separate Medicare Part D plan to cover medications. Part D plans are offered by insurance companies and vary in cost and which drugs they cover. You can join a Part D plan when you first become may be able to access for Medicare, or during the annual enrollment period (October 15 to December 7).

Plan N does not cover routine dental care, vision care, or hearing aids. Medicare itself does not cover these services, so no supplement plan does. Some Medicare Advantage plans (Part C) include dental or vision benefits, but Original Medicare with a supplement does not.

Plan N does not cover long-term care in a nursing home, assisted living, or at home. It covers only skilled nursing facility care for a limited time after a hospital stay. If you need ongoing custodial care, that is a separate insurance product or out-of-pocket expense.

Coverage for blood, hospice, and foreign travel

Plan N covers the first three pints of blood you need for a covered service. After that, you pay for blood, or the blood bank charges you directly. This is rarely a major expense but is worth knowing if you have a planned procedure.

For hospice care, Medicare covers most costs, but you may owe a copayment for drugs and respite care. Plan N covers these copayments.

Plan N includes emergency care during foreign travel — coverage for urgent or emergency services you receive outside the United States, but only during the first 60 days of a trip. This is limited coverage and does not extend to routine or planned care abroad. The plan typically covers 80% of approved costs after you pay a deductible.

How Plan N premiums compare to other plans

Plan N premiums are generally lower than Plan G or Plan F because you pay more out of pocket in certain situations. The trade-off is worth calculating for your own situation: if you see doctors frequently, the copayments add up. If you rarely need care, the lower premium may save you money overall.

Premiums vary by insurance company and by location. The same Plan N from two different insurers can cost $50 per month from one and $120 from another. Shopping among insurers in your area is important. You can switch plans during the annual enrollment period (October 15 to December 7) or during a special enrollment period if you have a may have access to life event.

Age also affects premium. Most insurers use attained age pricing, meaning your premium increases as you get older. Some use issue age pricing, where the premium is locked to your age when you first join, then increases only for inflation. Ask an insurer which method they use before you enroll.

When Plan N makes sense and when it does not

Plan N works well if you are generally healthy and do not see doctors often. The lower premium offsets the copayments you pay occasionally. It also works if you are comfortable managing multiple small out-of-pocket costs and want to keep your monthly insurance expense low.

Plan N may be less suitable if you have chronic conditions requiring frequent doctor visits. The copayments ($20 per visit, for example) add up quickly. In that case, Plan G or Plan F — which cover the Part B deductible and have no copayments — might cost less overall despite higher premiums.

Your choice also depends on your income and assets. If you may have access to for Medicaid in your state, Medicaid may cover costs that Plan N does not, making Plan N a better choice. If you have limited savings, a plan with lower out-of-pocket risk might be worth a higher premium.

Frequently Asked Questions

Does Plan N cover the Part B deductible?

No. You pay the Part B deductible ($240 in 2024) yourself. Plan N covers coinsurance after you meet this deductible, but not the deductible itself. This is one of the main differences between Plan N and Plan G.

What if I go to an emergency room?

Plan N covers the coinsurance for emergency room visits, but you pay a copayment at the time of the visit (typically $50). If the visit results in a hospital stay, Plan N covers your Part A deductible and hospital copayments as described above.

Can I use Plan N with Medicare Advantage instead of Original Medicare?

No. Supplement plans like Plan N work only with Original Medicare (Part A and Part B). If you have a Medicare Advantage plan (Part C), you cannot use a supplement plan. Supplement plans and Advantage plans are separate paths.

Does Plan N cover preventive care like colonoscopies or mammograms?

Yes, if Medicare covers the service as preventive care. Medicare covers many preventive services with no copayment or coinsurance. Plan N does not add anything to this coverage, but it ensures you pay nothing out of pocket for these services.

What happens if I do not join a Part D plan for prescriptions?

If you delay joining Part D without a valid reason, you may owe a penalty when you finally join. The penalty is added to your Part D premium for as long as you have the plan. It is better to join Part D when you first become may be able to access for Medicare, even if you do not take medications now.
