Switching From Plan G to Plan N: Worth It in 2026–2027?

Bottom Line

Switching from standard Plan G to N may pay off when premium savings exceed added copays and excess charges, provided you qualify. Check cheaper Plan G offers too; returning to G later may require underwriting.

Get help comparing G and N

Switching from standard Medigap Plan G to Plan N can save money if the annual premium reduction exceeds your added visit copays and Part B excess charges. The decision also depends on whether you can qualify for the replacement policy. Compare the yearly dollars before giving up Plan G’s more predictable cost sharing.

If you are also considering permanent life insurance, comparing IUL companies is a separate decision. Evaluate that need and its budget independently of your Medicare coverage.

Know what changes with Plan N

Plan G and Plan N are Medicare Supplement Insurance, also called Medigap. They supplement Original Medicare’s Part A hospital and Part B medical coverage. Medicare Advantage is a separate way to receive Medicare benefits. Standalone Part D provides prescription drug coverage; changing from G to N does not replace that separate coverage.

This comparison uses standard Plan G. High-deductible Plan G requires a different calculation. Massachusetts, Minnesota, and Wisconsin also standardize Medigap differently.

Start with Plan N copays and coverage gaps before comparing premiums:

• Office visits: Plan N requires up to $20 for some visits after the Part B deductible.
• Emergency room visits: Plan N requires up to $50 when the visit does not result in an inpatient admission.
• Part B excess charges: Plan N leaves these charges to you; standard Plan G covers them.

The plans share the same standardized Part A hospital benefits. Neither covers the Part B deductible. Plan N has no annual out-of-pocket maximum.

That deductible is $283 in 2026. Since you are responsible for it under either plan, do not count it as an additional cost of switching to N.

Check assignment before assuming excess charges will be zero

A provider who accepts Medicare assignment agrees to the Medicare-approved amount as full payment for a covered service. Some nonparticipating providers can charge more. In many cases, the limit is 15% above Medicare’s approved amount for nonparticipating providers.

Ask your regular doctors and specialists whether they accept assignment for your care. Repeat the check when using a new provider. A practice saying it “takes Medicare” does not necessarily answer the assignment question.

Calculate the annual savings

Compare Plan G versus Plan N over a full year using the premium you would actually pay after your current rate increase, if applicable.

The calculation is:

Annual net savings = annual premium reduction − Plan N office copays − Plan N ER copays − Part B excess charges.

Use your past year’s visits as a starting point, then add a scenario with more care. Count visits subject to the Plan N copay, rather than automatically assigning $20 to every medical service.

A hypothetical 2026 comparison

Suppose standard Plan G costs $185 monthly and Plan N costs $140 monthly. These are invented teaching figures, not quotes or available rates. The annual premium difference is $540.

Assume you meet the Part B deductible, have 10 office visits subject to the maximum $20 copay afterward, and have one ER visit subject to the maximum $50 copay. Assume no excess charges.

Plan N saves $290 in this example. The totals exclude unchanged Part B and Part D premiums, prescription expenses, and other costs outside this comparison.

Now test a year with 24 copay-bearing office visits and two qualifying ER visits. At the maximum copays, Plan N adds $580. That exceeds the $540 premium reduction, making N $40 more expensive before any excess charges.

With no ER copays or excess charges, 27 office copays of $20 would use up the entire $540 difference. Every excess-charge dollar reduces the remaining savings by another dollar.

If you switch partway through a year, use the actual months remaining. For a 2027 start date, rebuild the comparison with confirmed premiums and published 2027 Medicare amounts; the table above uses 2026 figures.

Confirm whether you can buy Plan N

You can seek a replacement Medigap policy outside fall open enrollment, but an insurer must be willing or legally required to issue it. A lower premium is useful only if you can obtain the policy.

Federal protections

Your six-month Medigap Open Enrollment Period begins on the first day of the month when you are at least 65 and enrolled in Part B. During that window, you can buy any Medigap policy sold in your state for which you are eligible without health-based rejection. Outside protected circumstances, medical underwriting may mean a denial or higher price.

The October 15–December 7 Medicare open enrollment period concerns Medicare Advantage and drug-plan changes for the following year. It does not restart your one-time Medigap enrollment period or generally guarantee a G-to-N switch without underwriting.

A federal guaranteed-issue right can be limited to specified plan letters, and several protections do not include Plan N. Ask which protection applies, whether it includes N, and what application deadline you must meet.

State protections can change the answer

Maryland provides a concrete example. For policyholders with Medigap policies issued in Maryland, the annual protected application period includes their birthday and the following 30 days. They can change insurers and move to equal or lesser benefits without underwriting. Maryland’s chart specifically permits standard G to N; it does not permit N to G under this birthday rule. Submit the application within the window, even though processing can finish afterward.

Elsewhere, ask your state insurance department which replacement protections apply. Do not assume another state uses Maryland’s timing or permitted plan changes.

What underwriting can involve

Without an applicable protection, the Medigap medical underwriting process can include health questions and review of medical information.

For example, Blue Cross and Blue Shield of Illinois’ published Secure application asks for height and weight, specified diagnoses and treatment within three years, and certain unfinished procedures or repeated hospitalizations within two years. It also asks about assistance with daily activities and authorizes medical-record review to evaluate the application. The form directs applicants with open-enrollment or guaranteed-issue protection to skip the health questions.

Those questions belong to that insurer’s Illinois form. Request the current application for your proposed policy, follow its lookback periods, and answer completely. Ask whether your quoted premium depends on health approval. Do not assume a switch within your existing insurance company automatically avoids underwriting.

Compare quotes and protect your existing coverage

To explore your Medicare plan switching options, compare keeping your current G, applying for another insurer’s standard G, and applying for N. Standardized basic benefits are the same within each letter, while premiums can differ substantially between insurers. A less expensive G policy may meet your budget without changing the benefit tradeoff.

Request written quotes for the same effective date. Confirm the price for your age and location, applicable discounts, how long discounts last, any application fee, and whether the quote assumes underwriting approval. Ask how premiums are set and obtain recent rate history. Treat that history as context, not a promise of future increases.

If you choose N, obtain written acceptance, the issued premium, and the effective date. Keep G while reviewing the replacement. Medicare provides a 30-day “free look” starting when you receive the new policy, and you pay both premiums during the overlap. Do not cancel G until you decide to keep N. Include the extra overlap premium in your first-year calculation.

After canceling G, buying it again later may require underwriting; returning is not guaranteed.

For your next comparison, gather your renewal notice, visit history, provider assignment answers, and written G and N quotes. Fill in both an expected-use year and a higher-use year. Choose N only if the remaining savings justify the extra bills and uncertainty for your budget.
