Medicare Part N Coverage: Benefits, Costs & How to Enroll
What is Medicare Supplement Plan N?
Medicare Supplement Plan N, commonly known as Medigap Plan N, is one of the ten federally standardized supplemental insurance options available to individuals enrolled in Original Medicare (Medicare Part A and Part B). Its primary purpose is to help policyholders cover the out-of-pocket costs-such as deductibles, coinsurance, and copayments-that Original Medicare does not pay. Unlike Medicare Advantage plans, Medigap policies like Plan N have no network restrictions, so you are free to see any doctor or specialist accepting Medicare across the United States.
Plan N is offered by private insurance companies, but its core benefits are standardized by federal law. This means every insurer must provide the same Plan N benefits, though premiums and added perks may vary. Because of its balance between coverage and affordability, Plan N is a popular choice for beneficiaries who want reduced monthly premiums while retaining meaningful coverage.

What Does Plan N Cover?
Medicare Supplement Plan N offers robust benefits aimed at minimizing your financial exposure with hospital and medical expenses under Original Medicare. Here’s how Plan N helps fill common coverage gaps:
Part A Coverage
- 100% of your Part A deductible for hospital stays
- 100% of Part A coinsurance and hospital costs for up to an extra 365 days after Medicare benefits end
- 100% coverage for skilled nursing facility coinsurance (up to 100 days)
- 100% of Medicare-approved hospice care coinsurance or copayment
- 100% of the first 3 pints of blood annually
Part B Coverage
- 100% of Part B coinsurance, except for modest copayments: up to $20 for most office visits and up to $50 for emergency room visits (waived if admitted as an inpatient)
Additional Benefits
- Foreign travel emergency: Plan N covers up to $50,000 in lifetime benefits for emergency care received outside the United States, with a $250 annual deductible and 20% coinsurance
- Skilled nursing facility care: Full coinsurance for eligible stays
Plan N’s comprehensive benefit structure makes it a smart choice for many Medicare enrollees focused on balancing monthly expenses with strong protection against major costs.
Plan N Coverage Gaps: What Isn’t Included?
Despite its robust benefits, Medigap Plan N does not cover certain out-of-pocket expenses. Understanding these gaps is critical when evaluating your Medicare supplemental insurance needs:
- Medicare Part B deductible: Plan N does not pay your annual Part B deductible (set at $257 for 2025)
- Part B excess charges: Plan N will not cover charges above Medicare-approved amounts (some providers charge up to 15% more); consider Plan G if this is a concern
- Prescription drugs: No prescription drug coverage is included; to add this, you must purchase a separate Medicare Part D plan
- Dental, vision, and hearing: Plan N does not cover routine dental, vision, or hearing services. If you want these benefits, a Medicare Advantage plan may be more suitable (but Medigap and Medicare Advantage cannot be held at the same time)

Eligibility Requirements and How to Enroll
Who Can Enroll in Plan N?
To enroll in Medicare Supplement Plan N, you must:
- Have active enrollment in Medicare Part A (hospital insurance) and Medicare Part B (medical insurance)
- Not be enrolled in a Medicare Advantage plan at the same time (switching is possible-see our guide on how to switch back to Original Medicare if necessary)
The Medigap Open Enrollment Period
Your best window to enroll is the Medigap Open Enrollment Period, lasting six months from the first day of the month in which you are both 65 (or older) and enrolled in Medicare Part B. During this period, you have guaranteed issue rights, which ensure insurers cannot deny your application or charge you extra based on health conditions or pre-existing conditions.
Enrolling Outside Open Enrollment
After your Open Enrollment Period ends, you can apply for Plan N at any point; however, most insurers will require medical underwriting. This means they can review your health status and potentially decline coverage or set higher premiums if you have certain medical conditions.
Step-by-Step Enrollment Process
- Check eligibility: Ensure you are enrolled in Medicare Part A and Part B
- Compare plans: Shop Plan N options from multiple insurers for cost and extra features
- Select an insurer: Evaluate companies on premiums, reputation, and customer service in your state
- Prepare documents: Have your Social Security number, Medicare Part A and Part B dates, and your Medicare Beneficiary Identifier (MBI) ready
- Submit your application: Apply online, by phone, or in person through a licensed agent
Coverage generally begins the month after your successful enrollment. For more guidance on changing from a Medicare Advantage plan to Plan N, consult our resource on applying for Medicare Advantage plans.
Costs and Premiums for Plan N
Premiums
Plan N is well-known for its moderate monthly premiums, which tend to be lower than those for Plan G-a plan with slightly broader benefits. Premiums are not set by the federal government and will vary based on factors such as your age, state and city of residence, gender, tobacco use, and (if applicable) your health history if enrolling after your Open Enrollment Period.
Out-of-Pocket Costs Under Plan N
Aside from premiums, you’ll pay certain out-of-pocket amounts, including:
- The Medicare Part B deductible ($257 in 2025)
- Up to $20 copayment for most doctor or specialist office visits
- Up to $50 copayment for emergency room visits, unless you’re admitted as an inpatient
- 20% coinsurance for foreign travel emergency care (after a $250 calendar-year deductible, up to a $50,000 lifetime limit)
These built-in copayments and cost-sharing features mean lower monthly premiums, but beneficiaries need to budget for the occasional out-of-pocket cost. If you want to minimize these surprise expenses, a plan like Medigap Plan G (which covers the Part B deductible and eliminates most copays) might suit you better, though it often comes at a higher monthly price.
Who Should Consider Plan N?
Medicare Supplement Plan N is ideal in several situations and for certain beneficiary profiles:
- People seeking solid coverage for hospital and medical expenses, with lower ongoing premiums
- Beneficiaries who don’t visit doctors or emergency rooms frequently and are okay with predictable small copays
- Retirees who travel internationally and value built-in foreign emergency care
- Individuals who want peace of mind against large hospital bills, especially with 100% coverage for the Part A deductible and coinsurance
- Those comfortable buying a separate Part D drug plan or using stand-alone dental/vision coverage as needed
On the other hand, you might look at a different Medigap plan if:
- You want to eliminate almost all out-of-pocket costs for medical care (such as by choosing Plan G or F)
- You need ongoing prescription, dental, vision, or hearing care integrated into your plan (consider Medicare Advantage instead)
- You’re likely to use the healthcare system heavily, making frequent copays an ongoing burden

FAQs About Medigap Plan N
Can I switch from Plan N to another Medigap plan?
Yes, switching is possible at any time, but outside of Open Enrollment or specific guaranteed-issue situations, insurers may require medical underwriting and can deny your application or raise rates based on your health. Some states offer a “Birthday Rule” allowing plan changes within a short window around your birthday without underwriting, so check your state’s laws for specifics. Also, see details in our guide on switching back to Medicare from Medicare Advantage.
How does Plan N compare to Plan G?
Plan G is more comprehensive, covering your Part B deductible and eliminating copays for doctor and emergency room visits. It’s typically more expensive monthly. Plan N costs less and is a better fit for those who want to minimize premiums and are comfortable with occasional copays and the Part B deductible.
What if I have a pre-existing condition?
During Open Enrollment, pre-existing conditions do not affect your acceptance or price. Outside this window, insurers may use medical underwriting and potentially decline coverage or increase your premium.
Can I have Plan N and Medicare Advantage simultaneously?
No. Federal law prohibits enrollment in both a Medigap plan and a Medicare Advantage plan at the same time. If you wish to switch from Medicare Advantage to Medigap, review our instructions for switching back to Medicare and supplemental coverage.
Does Plan N cover prescription drugs?
No, Part D prescription coverage must be purchased separately. See When Can You Change Your Medicare Part D Plan? for guidance on adding or changing prescription drug coverage.
What documents do I need to enroll?
Be prepared with your Medicare card or MBI, your Part A and B enrollment dates, Social Security number, birth date, and contact details. If applying after open enrollment, you may need to provide information about your health and medications.
When does coverage start?
Coverage under Plan N typically begins on the first of the month after your application is accepted and processed. Ensure you maintain your Medicare Part A and B enrollment to prevent any disruption in benefits.
