Can I change my Medigap plan at any time?
You can apply to change your Medigap (Medicare Supplement) plan at any time during the year, but approval is not guaranteed after your initial open enrollment window.
How Switching Works
- Anytime applications: You can submit an application to switch plans 365 days a year. There is no restricted annual window like the fall timeframe for Medicare Advantage.
- Medical underwriting: After your initial 6-month open enrollment period (which starts when you turn 65 and enroll in Part B), changing plans usually requires answering health questions.
- Risk of denial: Insurance companies can review your medical history and deny your application or charge higher rates based on your health status, unless you have special protections.
Exceptions and Guaranteed Rights
- Guaranteed issue rights: You can switch without medical underwriting in specific situations, such as losing employer coverage or moving out of a plan's service area. You can check your legal rights using the tools on Medicare.gov.
- State-specific rules: Some states have unique laws—like annual birthday or anniversary rules—that let you switch to an equal or lesser benefit plan without a health review. Check your local guidelines through your state insurance department.
- Best practice: Never cancel your current policy until your new application is officially approved and your new coverage is active.
How hard is it to change Medigap plans?
Changing Medigap plans can range from very easy to nearly impossible, depending on your health and when you try to switch.
When It Is Easy (No Health Questions)
- Initial Open Enrollment: During the first six months after you turn 65 and enroll in Medicare Part B, you can buy any Medigap plan. Insurance companies cannot deny you or charge more due to health problems.
- Guaranteed Issue Rights: In special situations—such as if your insurance company goes bankrupt or you lose employer coverage—you have a legal right to buy a new plan without a health review.
- State Birthday or Anniversary Rules: Some states (like California and Oregon) let you switch to an equal or lesser coverage plan around your birthday without answering health questions.
When It Is Difficult (Medical Underwriting)
- Outside Open Enrollment: If you are past your initial six-month window and have no special exceptions, you can apply for a new plan at any time of year, but you must pass medical underwriting.
- The Risk of Denial: The insurance company reviews your health history. They can deny your application, charge you a higher price, or make you wait up to six months before covering pre-existing conditions.
- Golden Rule: Never cancel your current Medigap policy until your new application is fully approved.
You can review official guidelines and state-specific protections directly through Medicare.

What is the most highly rated Medicare supplement plan?
Medigap Plan G is widely considered the most popular and comprehensive highly rated Medicare supplement plan available to new enrollees.
Because Medicare supplement (Medigap) benefits are strictly standardized by the government, a Plan G from one private insurance company provides the exact same core medical coverage as a Plan G from any other company. Ratings and "best plan" distinctions instead apply to the specific insurance carriers offering them based on cost, customer satisfaction, and stability of rate increases.
Top-Rated Insurance Carriers for Medigap Plans
- State Farm: Frequently ranks highest for overall customer satisfaction and slow, stable rate increases over time.
- AARP / UnitedHealthcare: The largest Medigap provider nationwide, recognized for massive enrollment numbers, wide availability, and extra member perks.
- Mutual of Omaha: Consistently praised for strong financial stability, high customer satisfaction, and fast claim processing.
- HealthSpring (formerly Cigna): Noted for having some of the most competitive, low initial monthly premiums on the market.
What Medigap Plan G Covers
- 100% of Part A coinsurance, hospital costs, and hospice care.
- 100% of Part B copayments or coinsurance.
- The Part A deductible.
- The only major item it does not cover is the annual Medicare Part B deductible ($283 in 2026), which you must pay out-of-pocket before coverage kicks in. (Note: Plan F covers this deductible too, but is legally closed to anyone who became eligible for Medicare on or after January 1, 2020).

Do doctors prefer Medigap or Medicare Advantage?
Most doctors prefer Medigap (Medicare Supplement) over Medicare Advantage because it avoids private insurance red tape.
Why Doctors Prefer Medigap
- Less Paperwork: Doctors bill Original Medicare directly, meaning faster and more predictable payments.
- No Prior Authorizations: Medigap does not require approval from a private insurance company before giving care. Studies show a vast majority of physicians are frustrated by Advantage plan pre-approval delays.
- No Network Limits: Patients can see any doctor or hospital nationwide that accepts Medicare.
Why Doctors Dislike Medicare Advantage
- Administrative Burden: Advantage plans require time-consuming referrals and pre-approvals.
- Care Denials: Private insurers often delay or deny treatments, which creates friction between the doctor and the patient.
- Restricted Networks: Doctors must navigate narrow HMO or PPO provider rules set by individual private companies.
What is the biggest mistake seniors make when enrolling in Medicare?
The biggest mistake seniors make when enrolling in Medicare is missing key enrollment deadlines, which can lead to permanent, lifelong late-enrollment penalties and gaps in medical coverage.
Top Medicare Enrollment Mistakes
- Missing the Initial Enrollment Period (IEP): Your window to sign up is a 7-month period that starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after. Missing this window without qualifying for a special enrollment period leads to delays and penalties.
- Failing to Understand Work Rules: Many seniors either sign up for Part B when they don't need to (because they are still working and covered by an employer with 20 or more employees) or fail to realize they must sign up when they retire, missing their 8-month special window.
- Ignoring Prescription Drug Coverage (Part D): Failing to sign up for Part D when first eligible—even if you take no medications—can trigger a permanent 1% penalty added to your monthly premium for every month you delayed.
- Confusing Advantage and Supplement Plans: Assuming a low-premium Medicare Advantage plan always means lower overall out-of-pocket costs without checking network restrictions, copays, and prior authorization rules. You can read more details on avoiding these errors via the AARP Medicare Guide.
What is the average monthly cost of Medicare Plan G?
The average monthly cost for Medicare Supplement Plan G typically ranges from $120 to $220, with many 65-year-olds paying between $100 and $180 per month.
You can check official details and guidelines on Medicare.gov regarding supplemental coverage.
Key Cost Details
- Overall range: $100 to $300+ per month, depending heavily on your location, age, and gender.
- Age increases: Premiums often start around $142 a month at age 65 and can increase as you get older (if the plan uses an attained-age pricing model).
- High-Deductible Plan G: Averages about $50 to $58 per month, but requires you to pay a $2,950 deductible in 2026 before benefits begin.
Additional Costs to Remember
- Part B Deductible: Plan G does not cover the annual Medicare Part B deductible, which is $283 in 2026.
- Part B Premium: You must still pay your standard Part B monthly premium on top of your Plan G premium.
Is Medigap plan G worth the cost?
Medigap Plan G is generally worth the cost if you want predictable healthcare expenses, frequently see doctors, or need extensive medical care, but it may be too expensive if you are generally healthy and prefer a lower monthly premium.
Benefits of Plan G
- Maximum Coverage: It covers almost all out-of-pocket costs left by Original Medicare (Parts A and B), including hospital deductibles, coinsurance, and Part B excess charges.
- No Network Limits: You can see any doctor or visit any hospital nationwide as long as they accept Original Medicare. No referrals are needed.
- Financial Predictability: Once you pay the annual Part B deductible ($283 in 2026), your covered medical care is paid at 100%.
Drawbacks and Costs
- Higher Premiums: Regular monthly premiums typically range from $120 to $250 (depending on your age, gender, and location), which can add up over time.
- Does Not Cover Everything: It does not pay for the annual Part B deductible itself, prescription drugs (Part D), routine dental, vision, or hearing care.
- High-Deductible Alternative: A High-Deductible Plan G is available in many states with much lower monthly premiums, but you must pay $2,950 out of pocket in 2026 before coverage starts.
Plan G vs. Alternatives
- Plan N: Offers lower monthly premiums than Plan G, but you must pay small office ($20) and ER ($50) copays, plus any Part B excess charges. Plan N is often a better value if you rarely visit the doctor.
- Medicare Advantage (Part C): Usually has lower or zero premiums and includes extras like dental or vision, but restricts you to specific provider networks and requires prior authorizations.
What is better, Medicare C or G?
Neither Medicare Part C nor Medigap Plan G is objectively "better"; instead, they serve different financial and medical needs, depending on whether you prefer low fixed monthly costs or predictable out-of-pocket medical expenses.
Medicare Part C (Medicare Advantage)
Medicare Advantage is an all-in-one alternative to Original Medicare offered by private companies.
- Cost: Features low or $0 monthly premiums, but you pay copays and coinsurance as you use care until you hit an annual out-of-pocket maximum.
- Network: Restricts you to specific local networks (like HMOs or PPOs) and often requires referrals to see specialists.
- Extra Benefits: Usually bundles prescription drug coverage (Part D) and includes extra perks like routine dental, vision, and hearing.
Medigap Plan G (Medicare Supplement)
Plan G is a supplemental policy that works alongside Original Medicare (Parts A and B).
- Cost: Requires a higher monthly premium, but covers nearly all of your out-of-pocket costs (like coinsurance and copays) after you meet the small Part B deductible.
- Network: Gives you the freedom to visit any doctor or hospital in the U.S. that accepts Medicare—no networks or referrals required.
- Extra Benefits: Does not include prescription drugs or dental/vision, requiring you to buy a separate standalone Part D plan.
Summary: Which should you choose?
- Choose Part C if you want lower monthly premiums, need extra dental/vision benefits, and don't mind staying within a specific doctor network.
- Choose Plan G if you want predictable medical bills, travel frequently, or see multiple specialists without needing referrals.
