What Is the Best Medigap Plan for 2027? Compare Your Options

Is Plan G still the best Medigap plan for most people in 2027?

Plan G can suit people who want broad coverage, but the sources do not establish one plan as best for most people. The practical question is whether its benefits justify its local premium compared with options that leave more costs to you.

Medicare.gov says Plan G covers Part A coinsurance and hospital costs, Part B coinsurance or copayments, the first three pints of blood, hospice coinsurance, skilled nursing facility coinsurance, the Part A deductible, Part B excess charges, and foreign travel emergency care up to plan limits. That breadth can make costs more predictable, though it does not mean every Medicare expense disappears.

For a useful starting point, first identify which costs you want a supplement to cover, then compare the plan letters available where you live. Medicare.gov’s comparison of Medigap plan benefits lays out the standardized benefits. A broader comparison of Medicare coverage choices is available in our guide to comparing Medicare plans for seniors.

Which Medigap plan makes sense if I want the lowest monthly premium?

The lowest-premium choice depends on local quotes and how much out-of-pocket cost you are willing to accept; the provided sources do not publish a nationwide 2027 price ranking. Plan N is one option to compare with Plan G, but its copayments mean the premium alone does not tell the whole story.

Medicare.gov says Plan N may require copayments of up to $20 for some office visits and up to $50 for emergency-room visits that do not result in inpatient admission. Plans K and L may also be worth comparing for people willing to share more costs: Medicare lists 2026 annual out-of-pocket limits of $8,000 for K and $4,000 for L. Those are 2026 amounts; verify the 2027 limits when published rather than carrying them forward.

A high-deductible version may be offered in some places. The federal Medicare guide lists a 2026 high-deductible Plan G threshold of $2,950, but that figure is not a 2027 threshold. Confirm the applicable amount before estimating what you might pay in a future year.

How do I compare the total yearly cost of a Medigap plan, including deductibles and copays?

Compare the annual premium plus the cost-sharing and deductible exposure described in the policy, rather than choosing by premium alone. The actual total depends on the insurer’s quote, location, discounts, and how often you use services subject to copayments or deductibles.

Medicare.gov notes that premiums can differ substantially between companies selling the same standardized letter plan, vary by location and other factors, and typically increase each year. Its Medigap cost guidance recommends treating estimated prices as a starting point and verifying current prices directly with insurers.

For each quote, record the premium and ask whether discounts apply, whether a high-deductible option is available, and whether Medicare SELECT provider restrictions affect the policy. Then note the plan’s cost-sharing, deductibles, and any annual out-of-pocket limit. A rough comparison can organize these known items, but it cannot predict actual claims or future premium changes.

Pricing method matters over time. The federal guide describes community-rated, issue-age-rated, and attained-age-rated premiums. Attained-age pricing can rise as the policyholder gets older; all three methods may also change for other factors. In Texas, the Department of Insurance similarly explains that issue-age pricing is based on age when the policy is purchased and attained-age premiums can increase on a birthday. Its Medicare Supplement Insurance Guide also recommends reviewing company complaint histories, not just prices and policy features.

Are the benefits of the same Medigap plan letter identical across insurance companies?

In most states, the basic benefits of a given Medigap letter are the same across insurers, but the premium and other factors can differ. Medicare.gov states that “the benefits in each lettered plan are the same, no matter which insurance company sells it.”

That standardization makes a same-letter comparison useful: compare Plan G from one insurer with Plan G from another, rather than treating a lower premium as a different set of core benefits. Still, verify policy details, availability, pricing method, discounts, and any Medicare SELECT restrictions. Medicare recommends contacting insurers for accurate quotes.

Timing can matter as much as the letter selected. The federal six-month Medigap Open Enrollment Period generally begins in the first month a person is both at least 65 and enrolled in Part B. During that one-time window, insurers generally cannot deny a policy they sell or charge more because of health problems. After it ends, switching may involve medical underwriting unless a guaranteed-issue right or state protection applies.

Do not confuse this Medigap window with fall Medicare open enrollment, which is associated with Medicare Advantage and prescription drug plan choices. It does not create a general guaranteed Medigap switching period. For free local counseling on available plans and costs, the federal guide recommends contacting SHIP. The Texas Department of Insurance lists its Texas SHIP contact number as 800-252-9240.
