I have federal retiree health insurance. Do I have to sign up for Medicare?

| No, retired federal employees covered under the Federal Employees Health Benefits (FEHB) program aren’t required to enroll in Medicare. Your federal retiree coverage can continue as your

primary coverage if you’ve been continuously insured for five years immediately before departing.

This isn’t the case for other types of retiree health insurance. Typically, health insurance coverage from a former employer, rather than a current employer, becomes secondary to Medicare

when you turn 65.

If you don’t sign up for Medicare when you leave your job, you could face gaps in coverage. But the rules are different for federal retiree coverage.

federal retiree coverage?

Enrolling in Medicare has its benefits even though your federal coverage can remain your primary coverage in retirement after 65. Consider the following before making a decision.

Enrolling in Part A. If you aren’t required to pay a premium for Part A, you may want to sign up for Medicare at age 65 or when you leave your federal job if you work beyond 65.

The federal Office of Personnel Management encourages federal retirees to enroll in Part A if their premiums are free. Federal employees in January 1984 began transitioning into the Social

Security system from the old Civil Service Retirement System and paying Social Security and Medicare taxes.

But if you’re working for a private-sector employer after retirement from your federal job and have a high-deductible health plan that allows you set aside pretax money in a health savings

account (HSA), you won’t be able to contribute to an HSA after enrolling in either part of Medicare.

The Part B dilemma. Think carefully about whether you want to delay enrolling in Part B. Doing so could come with a penalty if you change your mind later.

Part B costs $164.90 a month in 2023 for most people. It costs more if you’re single and your modified adjusted gross income is higher than $97,000, or higher than $194,000 if married and

filing jointly.

You can continue to receive full coverage from the FEHB plan after 65, unlike other types of retiree benefits that may not pay unless you enroll in Medicare. But if you decide to get Part B

later — if, for example, you think your federal health benefits have become too expensive when compared to Medicare — you could get stuck with a late enrollment penalty. The penalty adds 10

percent of the standard Part B premium for each 12-month period you could have had Part B but chose not to enroll.

The reason? You didn’t have coverage from a current employer during that time.
