Yes, Medicare Supplement (Medigap) plans are state-specific regarding availability, pricing, and regulations, although the coverage itself is standardized federally. While Medigap plans A-N offer the same benefits nationwide, premiums vary by state, and specific regulations (like guaranteed issue rights or laws for those under 65) depend on your state of residence.
These plans are available in all 50 states and Washington, D.C., and can vary in premiums and enrollment eligibility. Medigap plans are standardized; however, all of the standardized plans may not be available in your area.
All Medicare Supplement plans are offered by private insurance companies and regulated by federal and state governments. Not all plans are available in all states. In most states, these plans are named with letters: Plan A, Plan B and so on.
The "Medigap 6-Month Rule" refers to your Medigap Open Enrollment Period, the best time (first 6 months after turning 65 and enrolling in Medicare Part B) to buy a Medicare Supplement Insurance (Medigap) policy because insurance companies can't deny coverage or medically underwrite you, regardless of pre-existing conditions, allowing you to get any plan available in your state. Missing this window means insurers can deny you or charge more due to health issues, limiting your choices significantly, though some states offer additional protections.
Your answer:
You can keep your current Medigap policy no matter where you live, as long as you still have Original Medicare. If you want to switch to a different Medigap policy, you'll have to check with the Medigap insurance company about your options.
If you're enrolled in Medicare Part A and Part B (Original Medicare), and/or Medicare supplement insurance, these plans will cover you anywhere in U.S. as long as the health care provider accepts Medicare.
The most popular Medicare Supplement (Medigap) plan for new enrollees is Plan G, offering comprehensive coverage for nearly all Original Medicare costs (except the Part B deductible) at a predictable price, while Plan N is popular for lower premiums with some copays, and Plan F remains popular for those eligible for Medicare before 2020, covering everything, including the Part B deductible, notes Boomer Benefits.
These states have laws that will allow you to change Medicare supplement plans without underwriting. Below you will find information on each state's rules: California, Delaware, Indiana, Idaho, Illinois, Nevada, Kentucky, Louisiana, Maryland, Oklahoma, Oregon, Utah, Virginia and Wyoming, have the Medigap Birthday Rule.
Here are some of the biggest Medicare mistakes to avoid:
1. UnitedHealthcare / AARP – Best Plan Pairing: Plan G or Plan N. UnitedHealthcare, under the AARP brand, offers one of the largest and most recognized Medicare Supplement programs nationwide.
AARP does not necessarily argue that UnitedHealthcare is the right choice for every Medicare beneficiary, but it does proclaim it as a trusted healthcare partner and resource. Of course, there may be an additional reason other than UHCs good name. UnitedHealthcare pays AARP for the use of its name.
It was phased out at the start of 2020. Medigap Plan F is no longer offered as a new policy to those eligible for Medicare after January 1, 2020. However, if you're already enrolled in Plan F or were eligible for Medicare before 2020, you still have access to Plan F.
Top 5 states with the highest Medigap premiums
In most states, you can keep your current Medigap plan when you move to another state. However, before the move, you must contact the private insurance company that provides the plan and inform that provider of your upcoming relocation.
A doctor cannot refuse to accept your Medicare supplement, provided they accept Medicare itself. Medigap plans are designed to fill in the gaps of Original Medicare, which means that if a healthcare provider participates in Medicare, they are obligated to accept your Medigap coverage as well.
People leave Medicare Advantage (MA) plans due to difficulty accessing needed care (especially with worsening health), restrictive provider networks, complex prior authorization rules, and dissatisfaction with care quality, often feeling trapped as their health needs grow despite initial low costs and extra perks that become limiting. Issues with provider availability, network changes, and sometimes misleading marketing also drive disenrollment, pushing people back to Traditional Medicare for greater freedom, notes KFF.
A "good" Medicare Supplement (Medigap) plan costs roughly $90 to $300+ per month, with popular plans like Plan G averaging around $140-$180 and Plan N being slightly cheaper ($110-$140), though costs vary significantly by location, age, tobacco use, and the specific plan chosen. High-coverage options (like Plan G) are pricier, while plans with copays (like Plan N) or high-deductible versions (like HD Plan G) offer lower premiums for less upfront coverage.
Other factors that can affect your Medicare supplement rate
Inflation – Like other types of insurance premiums, Medicare supplement rates can be affected by inflation. If the overall costs for health care increase, you may see a change in your Medicare supplement premium rate.
State laws can provide further protections, but only four states— Connecticut, Massachusetts, Maine, and New York—require either continuous or annual guaranteed issue protections for Medigap for all beneficiaries in traditional Medicare ages 65 and older, regardless of their medical history.
