What is Medicare Supplement Guaranteed Issue?

Medicare Supplement Guaranteed Issue lets you get a Medigap policy, regardless of your age, gender, health status, or pre-existing conditions [1]. Insurance companies must sell you specific Medicare Supplement plans during these guaranteed issue periods without checking your medical history [1].
Insurance companies use medical underwriting to get into your medical history and current health. They need this to determine whether you qualify for coverage and what your premiums should be [1]. You can skip this process completely with guaranteed issue rights. This means insurers can’t turn you down or charge you more based on your health [1].
Medicare Supplement plans work differently from regular Medicare. They don’t have yearly enrollment periods, so you need to time your application carefully [1]. These guaranteed issue rights usually kick in under certain conditions outside your original 6-month Medigap Open Enrollment Period. This period begins when you turn 65 and enroll in Medicare Part B [1].
You can only buy certain Medigap plans with guaranteed issue rights. The available plans are A, B, C (if eligible before 2020), D, G, F (if eligible before 2020), K, and L [2]. Plan M isn’t an option, and Plan N’s availability depends on your insurance carrier [2].
Here’s what you get with guaranteed issue rights:
- No health questions to answer
- No exclusions or waiting periods for pre-existing conditions (if you didn’t have a coverage gap over 63 days)
- Your health won’t affect your premium costs [2]
You usually have 63 days to pick a new plan under these rules after losing your previous coverage [2]. It also matters that you lost your other coverage involuntarily to qualify in some states [2].
Note that guaranteed issue rights vary widely by state. Connecticut, Massachusetts, Maine, and New York offer guaranteed issue protections year-round as of 2024 [1]. These rules can change each year, so you should check what’s current.
Medicare Supplement Guaranteed Issue protects consumers in specific situations. This protection becomes especially important after your original Medigap Open Enrollment Period ends. After this period, companies can typically deny you coverage or charge more based on your health [3].
When do guaranteed issue rights apply?

Guaranteed issue rights activate under specific circumstances that create protection periods. Medicare beneficiaries can purchase Medigap policies without medical underwriting or health-based denials during these times.
Losing employer or union coverage
The law guarantees your right to coverage after your employer group health plan or union coverage that supplements Medicare ends. This protection includes retiree coverage and COBRA [1]. You need to get a Medigap policy within 63 days after your employer coverage ends [4]. These rights only apply if your coverage ends involuntarily [5]. Documentation of coverage termination should be kept safely, including letters and claim denials that prove eligibility [6].
Moving out of your Medicare Advantage plan‘s area
Your guaranteed issue rights trigger if you relocate outside your Medicare Advantage plan’s service area [7]. The window to purchase a Medigap policy opens 60 days before and closes 63 days after your coverage ends [2]. You can select Plans A, B, C (if eligible before 2020), D, F (if eligible before 2020), G, K, or L from any insurance company in your state during this time [8].
Your Medicare Advantage plan ends or changes
Your rights activate if your Medicare Advantage plan discontinues coverage in your area, terminates its Medicare contract, or exits the Medicare program [1]. The timeframe for buying a Medigap policy spans from 60 days before your coverage ends to 63 days after it ends [8].
You leave a Medigap or Medicare Advantage plan within 12 months
Medicare provides two “trial right” periods. The first applies if you joined Medicare Advantage at age 65 and switch back to Original Medicare within 12 months [9]. The second covers situations where you dropped a Medigap policy to try Medicare Advantage for the first time and return to Original Medicare within 12 months [1]. Both cases guarantee issue protection.
Your Medigap insurer goes bankrupt
Your rights activate if your Medicare Supplement insurance company declares bankruptcy or your coverage ends through no fault of yours [7]. A new Medigap policy must be requested within 63 days after coverage ends [8].
You were misled, or the plan broke rules
You have guaranteed issue rights if you leave a Medicare Advantage or Medigap plan because the company violated its contract or misled you [1]. Medicare might require you to file a complaint to verify this situation [8]. The deadline to apply for a new policy falls within 63 days after your coverage ends.
What plans are available under guaranteed issue?
Insurance companies must offer certain standardized Medicare Supplement plans under guaranteed issue rights. Your eligibility dates and specific circumstances that triggered your guaranteed issue right determine which plans you can get.
Plan A
Plan A has the core benefits that every Medigap policy must include [10]. The benefits cover Part A hospital coinsurance for days 61-90, lifetime reserve coinsurance for days 91-150, 365 lifetime hospital days beyond Medicare coverage, Parts A and B three-pint blood deductible, and Part B 20% coinsurance [10].
Plan B
Plan B offers all the core benefits of Plan A and provides additional coverage. Anyone with guaranteed issue rights can get this plan [2].
Plan C (if eligible before 2020)
Only beneficiaries who qualified for Medicare before January 1, 2020, can get Plan C [11]. New Medicare enrollees can’t buy this plan anymore, but people who qualified before the cutoff date can still access it through guaranteed issue rights [2].
Plan D
Plan D serves as the replacement for people who can’t get Plan C [11]. The plan provides detailed coverage and remains available through guaranteed issue rights, whatever your eligibility date [12].
Plan F (if eligible before 2020)
Just like Plan C, Plan F is only available to people who qualified for Medicare before January 1, 2020 [2]. Earlier Medicare enrollees can still get this once-popular plan with its extensive coverage options [11].
Plan G
Plan G has become the go-to choice for people new to Medicare since January 1, 2020 [11]. The plan offers reliable coverage and is available through guaranteed issue rights [12].
Plan K
Plan K provides less coverage than other plans but remains available through guaranteed issue provisions [2]. This plan takes a cost-sharing approach to Medicare supplement coverage.
Plan L
Plan L offers coverage levels different from those of Plan K and is available through guaranteed issue rights [2]. Both plans give you alternative coverage structures within the guaranteed issue framework.
State-specific rules and exceptions
Several states have expanded Medicare Supplement guaranteed issue rights through their own regulations beyond federal protections. State-specific rules give beneficiaries additional opportunities to purchase Medigap policies without medical underwriting.
Medigap guaranteed issue states
States’ Medigap consumer protections exceed minimum federal standards. Qualifying events, such as involuntary changes in employer coverage, trigger guaranteed issue rights in some states. 28 states require Medigap insurers to issue policies when applicants face involuntary changes in their employer coverage [13]. Nine states grant guaranteed issue rights to applicants who lose Medicaid eligibility [13].
States with year-round guaranteed issue
Connecticut, Massachusetts, Maine, and New York mandate detailed Medigap guaranteed issue protections [13][14][2]. Connecticut’s and New York’s policies allow continuous open enrollment throughout the year [13]. Maine requires insurers to offer Plan A during a one-month enrollment period each year [13]. Massachusetts provides guaranteed issue from February 1 through March 31 annually [8].
How California and New York differ
California’s “Birthday Rule” allows existing Medigap policyholders to switch to plans with equal or lower benefits within 60 days after their birthday each year, without underwriting [15][5]. New York State mandates detailed protections that prevent insurers from denying coverage or charging higher premiums based on health status [16]. New York’s community rating system bases premiums on location rather than age or health status [17].
Key Takeaways
Understanding Medicare Supplement guaranteed issue rights can save you from coverage denials and higher premiums during critical transition periods. Here are the essential protections every Medicare beneficiary should know:
• Guaranteed issue rights protect you from health-based denials during specific qualifying events like losing employer coverage or moving out of your Medicare Advantage plan’s service area.
• You have a limited 63-day window to apply for most guaranteed issue situations, making timing absolutely critical for securing coverage without medical underwriting.
• Only certain Medigap plans are available under guaranteed issue (Plans A, B, C, D, F, G, K, L), with Plans C and F restricted to those eligible before 2020.
• Four states offer year-round protections – Connecticut, Massachusetts, Maine, and New York provide enhanced guaranteed issue rights beyond federal minimums.
• Trial rights give you a safety net – you can return to Original Medicare within 12 months of joining Medicare Advantage at age 65 or switching from Medigap to Medicare Advantage for the first time.
These protections ensure you can access Medicare Supplement coverage when life circumstances change, regardless of your health status. Always verify your state’s specific rules, as many offer additional protections beyond federal requirements.
