Are you a senior aged 65? If so then you likely qualify for Original Medicare Parts A & B.
These policies help reduce your healthcare expenses during your golden years. As a senior, you have to manage your finances prudently during your retirement, and healthcare costs can severely impact your financial planning if you don’t prepare for them.
The issue with Medicare Parts A & B is that they only cover 80% of your total hospital and medical costs. You’re responsible for paying for the 20% balance. A Medigap policy helps you pay for the remaining out-of-pocket expenses not covered by Original Medicare.
Medigap plans come in ten options, A, B, C, D, F, G, K, L, M, & N. Each plan has different benefits, and some are more comprehensive than others. Understanding the various plans and how they work is central to choosing the right policy for your healthcare needs.
But how does Medicare supplement eligibility work? How can you enroll in a plan, and how do you start with Medigap?

How Does Medicare Supplement Insurance Work?
The Federal government standardizes the benefits offered in all Medigap plans. This regulation brings consistency to the industry, ensuring that you get the same level of benefits in each plan from any provider you sign up with for your Medigap policy.
So, what do Medigap policies cover? All Medigap plans offer the following benefits for Original Medicare Part A & B expenses.
- Part A coinsurance and hospital costs for up to 365 days after using up Medicare benefits.
- Part A hospice care coinsurance or copayment.
- Part B coinsurance or copayment.
- Blood transfusion costs for the first three pints of blood.
Plans F*, G, and N offer additional Medicare Parts A & B benefits.
- Part A deductible.
- Part B excess charges (Plan N doesn’t cover these charges).
- Skilled nursing facility care coinsurance.
- 80% of emergency healthcare costs when traveling outside the US for 60 days. ($250 deductible and $50,000 maximum apply).
- Unlimited coverage for all out-of-pocket costs.
*Plan F was phased out on January 1, 2020. It’s only available for people eligible for Medicare before this date. You can still buy a Plan F policy if you qualify for Medicare before this date, but terms and conditions apply. For newly eligible Medicare beneficiaries, the best option for near-comprehensive coverage is Plan G. Plan G has the same benefits as Plan F, but you don’t have coverage for the Part B deductible of $226.
Understanding Medicare Supplement Eligibility
The Open Enrollment Period
The “Open Enrollment” period for Medigap plans starts on the day of your 65th birthday, lasting six months from that date. During Open Enrollment, you can choose any Medigap plan and any provider for your insurer.
If you have pre-existing health conditions, the provider cannot use them to charge you higher-than-average premiums or deny you coverage. They must accept your application to join their scheme.
If you have pre-existing conditions and don’t have a history of at least six months of prior healthcare coverage before joining the scheme, the insurer can institute a three to six-month waiting period. During the waiting period, you pay premiums, but you don’t receive any Medigap benefits.
If you join after the Open Enrollment period ends, the insurer can make you complete “Medical underwriting.”
This process involves disclosing your pre-existing conditions in a questionnaire. If the insurer decides you’re a high-risk applicant, they can charge higher-than-average premiums or deny your application to join their scheme.
Federal law also imposes other protections for consumers when applying for Medigap policies. These include “guaranteed renewability,” meaning the insurer cannot cancel your policy if you continue paying your premiums.
Other protections are minimum medical loss ratios and rules stopping Medigap providers from selling policies to applicants with duplicate health coverage, such as a Medicare Advantage plan.
Special Guaranteed Issue Rights
Special guaranteed issue rights allow you to join a Medigap plan outside the Open Enrollment period without undergoing medical underwriting. Like the Open Enrollment period, the insurer must accept your application for a Medigap plan if you have special guaranteed issue rights.
28 states require insurers to issue plans to eligible beneficiaries if their employer changed their retiree healthcare benefits. Four states (CT, ME, MA, NY) require continuous or annual guaranteed issue protections for all Medigap beneficiaries in Original Medicare aged 65 and older, regardless of their pre-existing conditions and medical history.
Guaranteed issue protections stop insurers from denying Medigap plans to eligible applicants. If you recently lost your Medicare Advantage provider, you have a guaranteed issue right if you meet the following criteria.
- You no longer live in the service area for the Medicare Advantage plan.
- The company offering your Medicare Advantage plan lost its certification to sell plans.
- You canceled your Medicare Advantage plan within a year of enrolling in Original Medicare Part A.
For the following instances, you’re eligible for a guaranteed issue right for Medicare Supplement Plan A, Plan C, Plan D, Plan F, or High-Deductible Plan F.
- You canceled your Medicare Advantage plan because your insurer misled you or violated the contract.
- You canceled your enrollment in Medigap and enrolled in Medicare Advantage for the first time, then canceled the Medicare Advantage plan within the first year of coverage. (This condition applies to Plan N as well).
You also qualify for special guaranteed rights as a Medigap Plan A, C, D, F, or HD-F policyholder if you meet the following conditions.
- The company offering your Medicare supplement coverage goes bankrupt.
- You canceled your previous Medigap plan because it violated the contract.
- You canceled your Medigap plan for a Medicare Advantage plan, and within the first year, you switched back to your previous Medigap plan.
- These situations don’t apply to Medigap Plan N, G, or HD-G.
12 states offer guaranteed issue rights above and beyond the federal government requirements. These conditions apply to changing plans or the annual enrollment period.
The Medigap Birthday Rule
Six states have a “birthday rule” where you can change Medigap plans or providers. The birthday rule says if you decide to change plans, you must change to a plan with the same or lesser benefits.
This period lasts a specific time before and after your birthday every year. Here are the birthday rules for each state.
