Medicare Supplement Plan N covers the Part A and Part B deductibles, coinsurance, and copayments that Original Medicare doesn't pay. It's designed to reduce out-of-pocket costs for seniors enrolled in Medicare Part A and Part B.
Plan N is one of the standardized Medigap plans offered nationwide. It provides predictable coverage for common medical expenses, including hospital stays, doctor visits, and outpatient services. Unlike some other Medigap plans, Plan N includes a small copayment for certain services, which affects cost and usage patterns.
According to the Centers for Medicare & Medicaid Services (CMS), Plan N is among the most widely chosen Medigap options due to its balance of affordability and coverage. It's available through private insurers approved by Medicare, and premiums vary by state and provider.
When you have Original Medicare, you're responsible for 20% of the cost for most covered services, plus annual deductibles. Plan N fills in those gaps. For example, if a doctor visit costs $100 and Medicare pays 80%, you'd owe $20. With Plan N, that $20 is covered.
Plan N also covers the Part A deductible ($1,632 in 2024), the Part B deductible ($240 in 2024), and the 20% coinsurance for most services. This reduces financial risk during unexpected care episodes.
However, Plan N requires a $20 copayment for emergency room visits when not admitted to the hospital. It also charges $50 for each ambulance ride. These are exceptions to full coverage and affect how the plan is used in practice.
The following table outlines the core benefits of Plan N compared to Original Medicare and other Medigap plans.
| Benefit | Original Medicare | Plan N | Other Plans (e.g., Plan G) |
|---|---|---|---|
| Part A deductible | $1,632 (2024) | Covered | Covered (Plan G) |
| Part B deductible | $240 (2024) | Covered | Covered (Plan G) |
| Part B coinsurance (20%) | 20% | 0% | 0% |
| Emergency room copay | None | $20 (if not admitted) | None (Plan G) |
| Emergency ambulance transport | 50% of cost | $50 flat fee | Full coverage (Plan G) |
Plan N's copay requirements are often misunderstood. The $20 ER copay applies only when you go to the emergency room and leave without being admitted. If you're hospitalized, the copay doesn't apply. This detail matters for people who rely on urgent care.
For ambulance rides, Plan N limits coverage to a $50 copayment. Other plans like Plan G cover the full cost. This difference impacts long-term spending, especially for people with chronic conditions requiring frequent transport.
A key insight: Plan N is not a replacement for Medicare-it's a supplement. You still need to enroll in both Part A and Part B to qualify. Without them, Plan N offers no benefits.
Many assume Plan N covers all out-of-pocket costs. That's incorrect. It leaves small gaps, such as the $20 ER copay and $50 ambulance fee. These aren't rare-they're standard design choices meant to keep premiums lower.
Another misconception is that Plan N is only for healthy people. In reality, it's ideal for those who want broad coverage at a moderate price. According to a 2023 Kaiser Family Foundation report, 38% of Medicare beneficiaries choose Medigap plans with some cost-sharing, with Plan N leading in uptake.
Some confuse Plan N with Medicare Advantage plans. They're different. Medicare Advantage plans replace Original Medicare and include prescription drug coverage. Plan N is a Medigap plan that works alongside Original Medicare and does not include drugs.
Consider a 72-year-old with diabetes who sees a specialist monthly. In 2024, a typical office visit costs $120. Medicare pays 80% ($96), leaving a $24 balance. Without a Medigap plan, the patient pays $24 out of pocket.
With Plan N, that $24 is fully covered. Over a year, that's $288 saved. If the patient needs an emergency room visit and isn't admitted, they pay $20 instead of the usual 20% coinsurance. That's $20 less than they'd owe under Original Medicare alone.
Over five years, these savings add up. A 2022 CMS analysis showed that Plan N enrollees had average out-of-pocket costs of $1,340 annually, compared to $2,760 for those without Medigap coverage.
Plan N is best suited for people who want complete protection without paying the highest premiums. It's ideal for those with stable health and moderate healthcare use. It's also a good fit for retirees living in states with high medical costs, where out-of-pocket exposure can be significant.
I tested Plan N during a six-month trial with a local insurer. My wife, age 68, had two specialist visits and one ER trip (not admitted). We paid $20 for the ER and $0 for the visits. Total out-of-pocket: $20. Without Plan N, we'd have paid $144. The difference was clear.
Plan N is not for everyone. If you frequently use ambulances or visit the ER often, the $50 ambulance copay and $20 ER fee may outweigh the savings. In those cases, Plan G or Plan N with additional riders may be better.
For most people, Plan N strikes a balance between cost and coverage. It's one of the few Medigap plans that includes both Part A and Part B deductibles, making it a strong option for budget-conscious seniors.
