What Does Medigap Plan G Cover?

Medigap Plan G is the most comprehensive Medicare Supplement plan currently available to people newly eligible for Original Medicare. It covers more out-of-pocket costs related to Medicare Part A and Part B than other Medicare Supplement plans.

What Medicare Supplement Plan G Covers
  • Medicare Part A coinsurance and hospital costs up to an additional 365 days after Original Medicare benefits are used up
  • Medicare Part A deductible – $1,556 in 2022 (for each benefit period)
  • Medicare Part A hospice care coinsurance or copayment
  • Medicare Part B coinsurance – usually 20 percent of the Medicare-approved cost
  • Medicare Part B copayments – a fixed dollar amount your doctor or other health care provider charges
  • Medicare Part B excess charges – the amount a doctor or other health care provider can charge you over and above the Medicare-approved amount that a doctor can legally charge you for service
  • Skilled nursing facility care coinsurance
  • The first three pints of blood needed for medical procedures each year
  • 80 percent of your medical costs if you receive emergency medical care while traveling in a foreign country (up to your plan’s limits)

You must be enrolled in both Medicare Part A hospital insurance and Medicare Part B medical insurance to purchase Medigap Plan G. You cannot purchase Medigap Plan G if you have — or are planning to buy — a Medicare Advantage plan.

Medigap plans are standardized in most states — meaning that Medigap Plan G policies in one state will include everything included in Plan G policies sold in other states. But not every insurer sells all Medigap plans.

What Are the Key Differences Between Medigap Plan G and Plan F?

Medigap Plan G is a possible option for people who are no longer eligible for Medicare Supplement Plan F, which used to be the most comprehensive Medigap plan.

Key Differences Between Medigap Plan F and Plan G
Medigap Plan FMedigap Plan G

You should compare Medigap plans available in your area before buying a policy. Make sure you find a plan that best fits your health and financial needs.

William Howery, internal marketing consultant at Senior Market Sales, explains the benefits of Medigap Plan G.

How Much Does Medigap Plan G Cost?

You will have to pay a monthly premium for your Medigap Plan G policy. How much you pay depends on several factors, including your state of residence and your age at the time you purchase a Medicare Supplement plan.

The cost of your monthly premiums can vary from one insurance company to another. These companies use several methods to set their rates.

Common Methods Used to Set Medigap Plan G Premium Rates
Your monthly premium will be based on your current age, meaning your cost will increase as you get older.
Your monthly premium will be based on your age when you buy the policy meaning you’ll have lower premiums if you buy at a younger age.
Community Rated
Your monthly premium will be the same as everyone else who buys the same Plan G policy regardless of age.

Medigap Plan G high-deductible policies are also available in some states. These typically allow you to pay lower monthly premiums if you are willing to pay more out-of-pocket costs yourself.

High-deductible plans require you to pay $2,490 in Medicare deductibles, coinsurance and copayments before your Medigap Plan G policy pays for any of your costs.

You should compare your annual premium payments against your potential Plan G deductible — and consider your health care needs — to determine whether a high-deductible policy is the best choice for you.
