Medigap Plan A is the most basic of all Medicare Supplement insurance plans available to Medicare beneficiaries. Plan A covers the least amount of benefits of all Medigap options. It does cover some of the costs associated with Original Medicare. Plan A also leaves coverage gaps.

What is Medicare Supplement Plan A?

Many states offer Medicare Supplement policies for Medicare beneficiaries under age 65. In those states, not all plan letters are available. Plan A is one of the required plans in those states for beneficiaries under the age of 65.

You’ll notice the premiums of many of the states that offer Medicare Supplement plans for people under the age of 65 are significantly higher. The premium is the same in a few states as in someone turning 65. However, it’s more common to see the premium double or triple the cost compared to a beneficiary 65 or older.

The main reason for the higher costs is beneficiaries on Medicare due to disability will usually have higher medical costs.

The good news is there’s a less expensive option. Many beneficiaries that go on Medicare early due to a disability choose a Medicare Advantage plan. Upon their 65th birthday, they re-evaluate their situation during their second Medigap Open Enrollment Period upon turning 65.

Medicare Advantage plans are the same price and benefit level regardless of age, gender, or other factors that cause the Medigap prices to vary. These will give you an affordable option to protect you from the unpredictable costs of having Original Medicare only.
