Medigap Plan G covers all of the same out-of-pocket Medicare costs than Plan F covers, except for the Medicare Part B deductible.
In 2021, the Part B deductible is $203 per year. This $203 annual deductible equals $16.92 per month.

Plan G is the second-most popular Medigap plan. It is also the fastest-growing Medigap plan.2
What can affect the average cost of Medicare Supplement Insurance?
The average cost of a Medicare Supplement Insurance can be influenced by a number of factors.
- Location
2021 Medigap plan costs can vary quite a bit from one state to another. The cost of a Medicare Supplement Insurance plan can vary based on location in the same way that a gallon of gas or milk can. - Insurance carrier
Medigap plans are sold by private Medicare Supplement Insurance companies. These companies can set their own premium rates.
A licensed insurance agent can help you compare plans from several different Medigap plan providers. - Benefits
Because Plan F and Plan G provide more benefits than most other types of Medigap plans, Plan F and Plan G may have higher monthly premiums than other types of Medigap plans in some areas.
Other factors such as age, gender, smoking status and health can also affect Medigap plan rates.
When should I buy a Medicare Supplement Insurance Plan?
A good time to buy Medicare Supplement Insurance is during your Medigap Open Enrollment Period (OEP).
Your Medigap Open Enrollment Period begins as soon as you are:
- At least 65 years old
- AND enrolled in Medicare Part B
During your Medigap OEP, Medicare Supplement Insurance companies can’t use your health to determine your eligibility for a Medigap plan or to charge you higher plan premiums.
Outside of your Medigap Open Enrollment Period, you may have what are called “guaranteed issue rights.”
Having a guaranteed issue right means Medicare Supplement Insurance companies cannot perform any medical underwriting in determining your Medigap premium. In other words, you cannot be charged more for a plan because of your health. Your choice of plan type may be limited based on the guaranteed issue right you have.
There are several circumstances that could qualify you for a Medigap guaranteed issue right.
