Benefits come from the letter
In most states, the same letter provides the same standardized basic benefits across companies. Massachusetts, Minnesota, and Wisconsin standardize Medigap differently.

Best Medicare Supplement Insurance Plan: 2027 Comparison
The best Medicare Supplement insurance plan is the eligible policy that fits your preferred balance of monthly premium, predictable medical costs, provider access, travel, and financial risk. No letter is universally best. Plan G, Plan N, and high-deductible Plan G solve different problems, while Plan F remains limited to people who became eligible for Medicare before 2020.
Start by choosing the standardized benefit design—not a company logo. Then compare the same plan letter across licensed insurers using official quotes for your state, age, ZIP code, tobacco status where permitted, household circumstances, underwriting status, and intended effective date. A lower opening premium is not automatically a lower long-term cost.
If you searched for the best Medicare Supplement insurance plan “near me,” your state and ZIP code matter for policy availability, pricing, rating rules, under-65 rights, and switching protections. Standard Medigap generally follows Original Medicare’s provider rules rather than a Medicare Advantage county network, but Medicare SELECT policies can use networks.
2027 planning status: This page was substantively reviewed on August 25, 2026. Final 2027 Medigap premiums, annual deductibles, out-of-pocket limits, policy availability, underwriting practices, and state protections must be confirmed for the applicant and effective date. Current 2026 amounts are not presented as 2027 figures.
The Wellcare pathway is carrier-specific and concerns current Medicare Advantage options. It does not quote, compare, or enroll anyone in Medigap and is not an all-carrier comparison. The Blake Insurance Group form requests contact and a Medicare review; it is not an application or enrollment. Assistance depends on licensing, appointments, certifications, eligibility, and the intended effective date.
The short answer: choose by cost-sharing preference and purchase rights
Plan G may fit someone who values broad standardized coverage of eligible Original Medicare cost sharing after paying the Part B deductible. Plan N may fit someone comfortable with specified office and emergency-room copayments and paying Part B excess charges when they occur. High-deductible Plan G may fit someone who accepts a larger annual exposure before the policy pays in return for a different premium structure.
That comparison comes only after confirming eligibility and timing. A policy that looks ideal on paper is not a real option if it is not sold to the applicant, if underwriting prevents issue, or if a Medicare Advantage disenrollment and Medigap effective date are not safely coordinated.
Quick facts
What “best” should mean in a Medigap comparison
Premiums come from the insurer
Companies can charge different prices for the same letter. Rating method, location, applicant factors, discounts, and underwriting can affect the official quote.
Access comes from timing
The one-time federal Medigap Open Enrollment Period and specific guaranteed-issue rights can determine whether health underwriting may be used.
The table identifies the questions that must be answered before ranking any policy for one person. It separates standardized coverage from insurer- and applicant-specific terms.
| Decision area | General rule | What makes it personal |
|---|---|---|
| Coverage foundation | Medigap supplements Original Medicare Part A and Part B; Medicare processes covered claims first. | Part A and Part B dates, current coverage, and whether another payer or benefit program applies. |
| Standardized benefits | Lettered policies provide defined benefit packages in most states. | Needed cost-sharing protection, Plan C/F eligibility, high-deductible preference, and state standardization rules. |
| Company comparison | The same standardized letter can have different premiums across insurers. | Official quote, rating method, discounts, payment terms, service, rate history, and licensing. |
| Provider access | Standard Medigap follows Original Medicare rather than a Medicare Advantage network. | Whether each provider takes Medicare and the patient, accepts assignment, and whether the policy is Medicare SELECT. |
| Prescription coverage | Medigap policies sold after 2005 do not include modern outpatient drug coverage. | A compatible stand-alone Part D plan, medications, pharmacy network, formulary, and other creditable coverage. |
| Enrollment rights | The federal six-month Medigap Open Enrollment Period is generally one time; guaranteed-issue rights are event-specific. | Age, Part B date, prior coverage, notices, state law, disability status, underwriting, and deadline. |
| 2027 status | Standardized designs remain the comparison foundation. | Final premiums, annual thresholds, policies sold, underwriting practices, and state protections for the effective date. |
Do not let a sales ranking replace these questions. A policy can have broad benefits but an unaffordable premium. Another can have a lower premium but expose the policyholder to cost sharing they dislike. “Best” should describe the applicant’s fit, not a nationwide winner, carrier endorsement, or unsupported savings claim.
Plan comparison
Plan G, Plan N, high-deductible G, and legacy Plan F
Plan G, Plan N, and high-deductible Plan G are useful starting points because they represent three distinct approaches: broader first-dollar cost-sharing protection after the Part B deductible, selective member cost sharing, and greater upfront risk. Plan F belongs in the discussion only for applicants who were eligible for Medicare before January 1, 2020.
The summary below is an orientation, not a replacement for Medicare’s current standardized benefit chart, the insurer’s outline of coverage, or state-specific policy forms. Final documents control.
| Feature | Plan G | Plan N | High-deductible Plan G | Plan F |
|---|---|---|---|---|
| Basic structure | Broad standardized benefits after the Part B deductible. | Broad benefits with specified Part B service copayments and no coverage for Part B excess charges. | Plan G benefits begin after the applicable annual high deductible is met. | Broad standardized benefits that include the Part B deductible under its design. |
| Part B deductible | Not covered. | Not covered. | Not separately covered and counts within the high-deductible structure according to current rules. | Covered, but the policy is restricted by pre-2020 Medicare eligibility. |
| Part B service cost sharing | Part B coinsurance is covered after the deductible under the standardized design. | Specified office and emergency-room copayments can apply. | The beneficiary pays eligible costs until the annual high deductible is met; policy benefits then apply. | Covered under the standardized design. |
| Part B excess charges | Covered. | Not covered. | Covered after the high deductible is satisfied according to policy terms. | Covered. |
| Premium pattern | Must be quoted; do not assume it is highest in every market. | Must be quoted; potential premium difference must be weighed against cost sharing. | Often designed around a lower premium and greater initial exposure, but the official quote controls. | Must be compared with available alternatives for an eligible applicant. |
| Who may prefer it | Someone prioritizing predictable Medicare-covered medical cost sharing. | Someone comfortable with defined cost sharing and possible excess-charge exposure. | Someone with cash reserves and tolerance for a larger annual deductible. | An eligible pre-2020 beneficiary who confirms the premium and long-term value. |
Plan G: broader predictability, but not zero healthcare spending
Plan G covers the standardized benefit categories shown in the official chart except the Medicare Part B deductible. It does not eliminate the Part B premium, a separate Part D premium, prescription expenses, or services Original Medicare generally does not cover. Routine dental, vision, hearing aids, long-term custodial care, and most foreign care remain separate considerations unless another arrangement applies.
Plan N: evaluate copayments and excess-charge exposure
Plan N pays Part B coinsurance except for specified copayments for certain office and emergency-room visits. It does not cover Part B excess charges. A provider who does not accept Medicare assignment may be permitted to bill an excess amount where federal and state rules allow it. Ask providers about Medicare participation and assignment, but do not assume Plan N is unsuitable simply because excess charges are possible.
High-deductible Plan G: compare premium savings with annual exposure
The policyholder pays Medicare-covered costs up to the annual high deductible before the policy begins paying benefits. The deductible changes by year, so the 2027 amount must come from official materials. Compare the annual premium difference with the additional amount the applicant could pay in a higher-use year and confirm which expenses count toward the threshold.
Plan F: eligibility does not prove value
Plan F and Plan C generally cannot be sold to people who became eligible for Medicare on or after January 1, 2020. People eligible before that date may still be able to buy them if available and otherwise eligible. Covering the Part B deductible does not automatically make Plan F the better value; compare its premium with eligible alternatives and consider underwriting or switching rights.
Plans K, L, M, and other letters can still deserve review
A comparison should not force every applicant into G, N, or high-deductible G. Plans K and L use percentage cost sharing and annual out-of-pocket limits. Plan M shares a portion of the Part A deductible. Plans A, B, and D provide other standardized combinations. Availability and suitability must be checked for the applicant’s state and goals.
Premiums and total cost
Compare a full-year budget, not one monthly premium
The lowest Medigap premium is not always the lowest total cost, and the broadest policy is not always worth its premium difference. Build a routine-care scenario and a higher-use scenario. Include costs outside the policy so the comparison reflects the person’s real Medicare arrangement.
Annual Medigap premium + Part B premium + Part D premium and drug costs + uncovered medical cost sharing + noncovered services
This formula is not a quote. It is a checklist that prevents a Medigap policy from being evaluated in isolation. Income-related Medicare amounts, late-enrollment penalties, employer or retiree benefits, Medicaid, Medicare Savings Programs, and Extra Help can alter the final budget.
Understand how the policy is priced
Medicare describes three common rating approaches. State law and insurer practice determine which approaches may be used. Regardless of the method, premiums can change because of inflation, healthcare costs, approved rate actions, discounts ending, or other lawful factors. No rating method guarantees a flat lifetime premium.
| Rating method | How age is generally used | Question to ask |
|---|---|---|
| Community-rated | Premium is generally not based on the individual’s age. | Which non-age factors can change the premium, and does the quote include a temporary or conditional discount? |
| Issue-age-rated | Premium is based on age when the policy is purchased and does not rise solely because the person gets older. | How have premiums changed for inflation or other reasons, and what happens if the policy is replaced later? |
| Attained-age-rated | Premium is based on current age and can rise as the policyholder ages. | How frequently can age-related changes occur, and what other approved increases can apply? |
Compare the same letter and effective date
Standardization means the same plan letter provides the same basic benefits across companies in most states. Compare Plan G to Plan G for the same applicant and date. Record the official premium, rating method, household or payment discount only when documented, discount duration, underwriting class, payment schedule, and any Medicare SELECT or high-deductible designation.
Ask about recent approved rate changes and the insurer’s rate history where reliably available, but do not treat past performance as a guarantee. A newer policy block can have limited history. A low introductory quote can change, while an initially higher quote is not automatically more stable. Use verified filings and policy information rather than predictions.
Test three care scenarios
- Low-use year: premiums, the Part B deductible, limited visits, current prescriptions, and routine services outside Medigap.
- Expected year: recurring primary and specialist care, therapy, imaging, equipment, outpatient procedures, and known prescriptions.
- High-use year: hospitalization, surgery, rehabilitation, skilled nursing coinsurance, infusion, dialysis, or repeated specialty care.
The goal is not to predict illness. It is to decide whether the applicant prefers a larger predictable premium, more point-of-service cost sharing, or a higher deductible backed by available savings. The preferred tradeoff can differ between two people with identical Medicare eligibility.
Eligibility and timing
The right to buy can matter more than the plan ranking
Someone generally needs Original Medicare Part A and Part B to buy Medigap. A Medigap policy covers one person, so spouses need separate policies if both want coverage. State residence, age, disability status, prior coverage, and the reason for applying can affect the policies and protections available.
The federal Medigap Open Enrollment Period is one time
The six-month federal window begins the first month someone is both age 65 or older and enrolled in Part B. During that period, an insurer cannot use medical underwriting to deny a Medigap policy it sells to the applicant or charge more because of health problems. The period does not repeat each fall.
After the window ends, the applicant may face medical underwriting where permitted unless a guaranteed-issue right or broader state protection applies. An insurer may decline the application, offer fewer options, or use a different lawful premium. Under-65 Medigap rights vary significantly by state because federal law generally does not require companies to sell Medigap to people under 65.
Guaranteed-issue rights are event-specific
Defined events can create a limited right to buy certain Medigap policies without health-based denial. Examples can include the loss of specified employer or union supplemental coverage, certain Medicare Advantage plan terminations or service-area moves, a Medigap company failure, or an eligible Medicare Advantage trial right. Each event has its own policy choices, proof, and deadline.
Keep termination notices, plan letters, move records, coverage certificates, emails, and Medicare effective-date documents. A common federal application window can begin before coverage ends and extend no more than 63 days afterward, but the exact event controls. State law may add protections or switching opportunities.
Leaving Medicare Advantage does not automatically guarantee Medigap
A Medicare election period may allow someone to return to Original Medicare, but Medigap acceptance is a separate question. Confirm the guaranteed-issue or trial right, underwriting result, written policy acceptance, premium, Part D election, and all effective dates before ending current protection.
Changing one Medigap policy to another requires care
Outside open enrollment or a protected right, the new insurer may use underwriting where allowed. Medicare provides a 30-day free-look period when replacing one Medigap policy with another, and the applicant may pay both premiums during that period. Do not cancel the old policy until the new policy is issued, reviewed, and effective.
A permanent move usually does not require giving up standard Medigap as long as the policy remains in force and Original Medicare continues, but the premium can change. Medicare SELECT uses network rules and has separate move and switching protections. A separate Part D plan also uses service areas and may need to change after a move.
Providers, travel, and prescriptions
A Medigap letter is only one part of the coverage arrangement
Standard Medigap generally does not create its own nationwide physician network. Original Medicare decides whether the service is covered and pays first; the Medigap policy pays according to its standardized benefits. A provider can participate in Medicare and accept assignment, accept Medicare without taking assignment in every case, or opt out.
Verify that each doctor, hospital, laboratory, imaging center, therapist, equipment supplier, and facility accepts Medicare and the patient for the planned service. “Takes Medicare” does not guarantee a practice is accepting new patients. Plan N shoppers should also understand assignment and possible excess-charge exposure.
Medicare SELECT is the network exception
A Medicare SELECT policy can require the member to use specified hospitals or doctors for full benefits, subject to emergency and policy rules. It may have a different premium. Ask whether a quote is SELECT, review its network, and understand move or switching rights before comparing it with a standard policy.
Domestic travel and foreign emergencies are different
With standard Medigap, a traveler can generally use Medicare-participating providers in the United States under Original Medicare rules. That does not guarantee access to every provider or cover services Medicare excludes. Certain standardized letters include limited foreign-travel emergency coverage, subject to deductibles, percentages, timing, and lifetime limits. It is not comprehensive international medical insurance.
Part D remains separate
Medigap policies sold after 2005 do not include modern outpatient prescription drug coverage. Compare a compatible stand-alone Part D plan using every medication’s name, strength, dosage form, quantity, refill frequency, and preferred pharmacy. Check formulary inclusion, tier, deductible treatment, prior authorization, step therapy, quantity limits, and specialty-pharmacy requirements.
A strong Plan G or Plan N comparison can still fail the household budget if the Part D plan poorly matches the medication list. Review Part D annually because formularies, pharmacy relationships, and costs can change. Medigap benefits do not standardize Part D.
Medigap does not cover every health-related expense
Standard Medigap generally does not cover routine dental care, routine vision care, hearing aids, private-duty nursing, or long-term custodial care. It also does not pay Medicare Advantage cost sharing. Budget for uncovered services and evaluate separate coverage only when it fits the person’s needs.
Selection checklist
Choose a Medicare Supplement plan in seven steps
Confirm Medicare eligibility
Record Part A and Part B effective dates, age, Medicare eligibility basis, permanent state and ZIP code, current coverage, and intended effective date.
Identify the purchase right
Determine whether the applicant is in Medigap Open Enrollment, has a guaranteed-issue or trial right, benefits from state law, or may face underwriting.
Select benefit designs
Use the official chart to compare Plan G, Plan N, high-deductible G, and any other eligible letters. Do not begin with a carrier name.
Build realistic cost scenarios
Compare annual premiums and remaining cost sharing in low-use, expected-use, and high-use years. Include Part D and noncovered services.
Compare the same letter
Obtain official quotes for the same applicant, letter, policy type, and date. Record rating method, discounts, underwriting class, and payment terms.
Verify providers and prescriptions
Confirm Original Medicare participation, assignment concerns, Medicare SELECT networks, travel needs, and a compatible Part D plan using the complete drug list.
Coordinate acceptance and dates
Keep written quotes, applications, notices, approvals, policy delivery, premium records, Part D confirmation, and cancellation instructions before replacing coverage.

Frequently asked questions
Best Medicare Supplement Insurance Plan FAQs
What is the best Medicare Supplement insurance plan for 2027?
There is no universal winner. The best fit depends on eligibility, desired benefits, premium budget, cost-sharing tolerance, providers, travel, state protections, underwriting, and a compatible Part D arrangement. Final 2027 terms must be verified.
Is Plan G the best Medigap plan?
Plan G offers broad standardized benefits but does not cover the Part B deductible. It may suit someone prioritizing predictable medical cost sharing, but its official premium and the applicant’s alternatives determine value.
Is Plan N better than Plan G?
Neither is automatically better. Plan N can involve specified office and emergency-room copayments and does not cover Part B excess charges. Compare its premium difference with expected use and risk tolerance.
Who may prefer high-deductible Plan G?
Someone who can absorb a larger annual deductible and prefers a different premium structure may consider it. Compare the official 2027 deductible, what counts toward it, premium difference, and high-use exposure.
Can anyone buy Plan F?
No. Plan F is generally limited to people eligible for Medicare before January 1, 2020. Availability, underwriting, and state rules still apply even when the person meets that eligibility date.
Does Plan G cover the Part B deductible?
No. Standard Plan G does not cover the Medicare Part B deductible. Confirm the official 2027 deductible rather than using a prior-year amount.
Does Plan N cover Part B excess charges?
No. Standard Plan N does not cover Part B excess charges. Ask providers whether they accept Medicare assignment and check applicable state protections.
Are Medigap benefits the same at every company?
In most states, policies with the same letter have the same standardized basic benefits. Premiums can differ. Massachusetts, Minnesota, and Wisconsin use different standardization systems.
Why do companies charge different prices for the same plan letter?
Pricing can reflect the insurer’s rating method, location, applicant factors allowed by law, discounts, underwriting status, and approved rates. Compare official same-letter quotes for one applicant and date.
What are community-, issue-age-, and attained-age-rated policies?
They are common ways insurers incorporate age into premiums. Community rating generally does not base premium on individual age; issue-age uses age at purchase; attained-age uses current age. Other increases can still occur.
Does Medigap include prescription coverage?
Modern Medigap policies do not include outpatient prescription drug coverage. A person may need a compatible stand-alone Part D plan unless other creditable drug coverage applies.
Can I use any doctor with Medigap?
Standard Medigap follows Original Medicare, but no policy guarantees every provider accepts Medicare, the patient, or a particular service. Medicare SELECT may require specified providers for full benefits.
When is Medigap Open Enrollment?
The federal six-month period generally begins the first month someone is both age 65 or older and enrolled in Part B. It is generally a one-time window.
Does Medigap open enrollment repeat every fall?
No. The October 15–December 7 Medicare Open Enrollment Period applies to Medicare Advantage and Part D elections. It does not create a new federal Medigap open-enrollment right each year.
Can a Medigap insurer ask health questions?
Outside Medigap Open Enrollment or a guaranteed-issue protection, medical underwriting may apply where permitted. State law can provide broader rights, so timing and residence matter.
Can I change Medigap plans whenever I want?
You may ask about applying, but an insurer may use underwriting or decline the application outside protected periods where allowed. Confirm new acceptance before canceling existing coverage.
Can I have Medicare Advantage and Medigap together?
No. Medigap supplements Original Medicare and cannot pay Medicare Advantage premiums or cost sharing. A future Medigap effective date may be arranged when someone validly returns to Original Medicare.
What if I have Medicare before age 65?
Federal law generally does not require insurers to sell Medigap to people under 65. State rules may create options or protections. Check the state insurance department for the applicant’s residence.
Are final 2027 Medigap prices available?
Not necessarily. Obtain an official applicant-specific quote for the intended effective date. Do not treat 2026 premiums, deductibles, limits, discounts, or policy lists as confirmed 2027 terms.
Does the Wellcare button compare Medigap policies?
No. It is a carrier-specific pathway for current Wellcare Medicare Advantage options. It does not quote or compare Medicare Supplement policies and is not an all-carrier comparison.
Does the Blake Insurance Group form enroll me?
No. The form requests contact and a Medicare coverage review. Enrollment or policy issuance requires separate authorized applications, eligibility confirmation, insurer acceptance when applicable, and coordinated effective dates.
Find the best fit by comparing complete coverage arrangements
Confirm your Medigap purchase rights, compare eligible benefit letters, obtain same-letter quotes, model a full-year budget, pair the choice with Part D, and coordinate every effective date before replacing coverage.
The review form is not an application. The Wellcare pathway concerns carrier-specific Medicare Advantage options and does not compare or enroll anyone in Medigap.
