Medigap Plan G covers all gaps in Original Medicare except for the annual Part B deductible.
Medigap Plan N features lower premiums than Plan G but requires copayments of up to $20 for doctor visits and $50 for emergency room visits.
Both Plan G and Plan N cover the Part A deductible, skilled nursing facility care coinsurance, and Part B coinsurance.
Navigating the transition into Medicare can feel like trying to piece together a complex puzzle—especially when it comes to out-of-pocket costs. Medicare Supplement plans, also known as Medigap, have become an increasingly popular way to find peace of mind and bolster Original Medicare coverage. Among the most trusted options are Plan G and Plan N, two Medigap policies famous for offering robust financial protection while keeping monthly premiums in check.
Medicare Plan G and Plan N are thoughtfully designed to bridge the sometimes frustrating gaps left behind by Original Medicare (Parts A and B). By helping to absorb out-of-pocket expenses—such as copayments, coinsurance, and deductibles—these plans give you the financial stability you deserve when managing your health.
Plan G has earned a stellar reputation for its comprehensive coverage. It takes care of almost all the residual costs that Original Medicare doesn't cover, leaving you responsible only for the annual Medicare Part B deductible.
Plan N, meanwhile, offers a remarkably similar safety net to Plan G but introduces a few gentle cost-sharing measures. You might see small copayments when you visit the doctor or head to the emergency room. Because you take on a slight bit of the risk, the insurance companies reward you with lower premiums. This makes Plan N a highly attractive option for retirees who want to protect their savings while enjoying substantial coverage.
Monthly Premiums
One of the most noticeable differences between Plan G and Plan N will show up on your monthly bill. Because Plan G essentially removes the guesswork from your medical expenses, it typically commands a higher premium. You can generally expect Plan G to run between $120 and $300 a month, depending on variables like your age, where you live, and the specific insurance carrier you choose.
On the flip side, Plan N frequently boasts lower monthly premiums, usually hovering between $90 and $250. This upfront savings makes Plan N an appealing choice if you're keeping a watchful eye on your monthly healthcare budget.
Out-of-Pocket Costs
In exchange for those sweeter monthly premiums, Plan N requires you to chip in for a few out-of-pocket expenses that Plan G completely shields you from. With Plan N, you can anticipate copayments of up to $20 for typical doctor visits and up to $50 for emergency room visits that don't end in being admitted to the hospital. Furthermore, Plan N doesn't step in to cover Part B excess charges. If your healthcare provider happens to charge more than the Medicare-approved amount, you could be on the hook for the difference.
Plan G takes a different route, covering all of these extra expenses—again, everything except for the Part B deductible. It’s the closest thing to a "set it and forget it" approach to out-of-pocket costs.
Here’s how they compare:
| Feature | Plan G (Monthly Cost) | Plan N (Monthly Cost) |
| Monthly Premium | $120 – $300 | $90 – $250 |
| Part B Deductible | Not Covered ($283) | Not Covered ($283) |
| Copayments | None | $20 (doctor visits), $50 (ER visits) |
| Part B Excess Charges | Covered | Not Covered |
Coverage Gaps
While both Plan G and Plan N do an excellent job of mopping up most out-of-pocket costs left by Original Medicare, there are a few nuanced differences you should be aware of:
Part B Excess Charges
A major dividing line between the two policies is how they handle Part B excess charges. These charges rear their head when a healthcare provider legally bills you up to 15% more than the Medicare-approved amount for a service. With Plan G, you don't have to sweat it; these charges are fully covered. With Plan N, you would be responsible for paying that extra difference out of your own pocket.
Emergency Room Visit Costs
If you have Plan N and find yourself in the emergency room, you may need to pay up to $50 if the visit doesn't result in an inpatient admission. Plan G waves goodbye to this copayment entirely, making it a more comforting choice for anyone who dreads unexpected healthcare bills.
Consider Plan G if your primary goal is comprehensive coverage and you want to completely avoid sudden, unexpected medical bills. It takes care of nearly every out-of-pocket cost once you've met your Part B deductible, paving the way for a highly predictable healthcare experience. If you find yourself visiting specialists frequently, or if you live in a state where providers often charge Part B excess fees, Plan G offers undeniable convenience and comfort.
Consider Plan N if you'd prefer to shrink your monthly premiums and you don't mind managing the occasional out-of-pocket expense. Plan N strikes a beautiful balance between robust coverage and everyday affordability. It's often the ideal fit if you are in generally good health, don't anticipate frequent medical care, and are perfectly comfortable handling a modest copay here and there.
Eligibility
To take advantage of a Medigap policy like Plan G or Plan N, you first need to be enrolled in Medicare Part A and Part B. Medigap plans are typically available to individuals aged 65 and older, though some states also extend eligibility to those under 65 who have qualifying disabilities.
Enrollment Period
Timing is everything. The absolute best time to sign up for Medigap is during your Medigap Open Enrollment Period. This golden window opens the month you turn 65 and are enrolled in Part B, and it lasts for six months. During this period, you have the right to purchase any Medigap policy sold in your state without the fear of medical underwriting. This means insurance companies cannot charge you a higher premium or deny you coverage simply because of pre-existing health conditions.
How to Enroll in Medicare Plan G or N:
At the end of the day, choosing between Medicare Plan G and Plan N is a highly personal decision rooted in your financial preferences and health expectations. Plan G wraps you in comprehensive coverage with virtually no out-of-pocket costs, making it the premier choice for anyone prioritizing peace of mind. Plan N, conversely, offers a sensible, lower-cost alternative with minor cost-sharing, perfectly suited for those who are relatively healthy and want to save on monthly premiums.
Whichever path you choose, adding a Medigap plan to your Medicare toolkit can dramatically reduce your out-of-pocket expenses and deliver the profound financial security you deserve during your retirement years.
