Medigap Plans are standardized by the Federal Government which means that no matter where you're located or which carrier you choose, each individual Medigap Plan will offer the same benefits and coverage. That being said, availability and costs will depend on your location as well as the carrier you choose.
Because Medigap plans are sold by private insurance companies such as Aetna, the cost of each plan can vary from one carrier to the next, but we have a guide on medigap costs!
Some companies that sell Medicare Supplement Insurance may offer discounts to women, non-smokers and other enrollees, as well as married couples.
If you don't sign up for a Medicare Supplement Insurance plan when you first become eligible or when you have a guaranteed issue right, you could be subject to medical underwriting.
That means the insurance company selling the plan can base your premium on the status of your health. The worse your health, the higher your premiums might be. Depending on your health, you could even be denied a Medigap plan all together.
If you sign up for a Medigap plan during your Medigap Open Enrollment Period (OEP), you do not have to go through medical underwriting.
Your Medigap Open Enrollment Period starts as soon as you are at least 65 years old and enrolled in Medicare Part B.
In addition to your Medigap OEP, there are several Medigap guaranteed issue rights that allow you to sign up for a Medigap plan without medical underwriting. However, your choice of plan type may be limited.
