Medicare or Work-based insurance? Maybe both?

Medicare or Work-based insurance? Maybe both?

Almost 20 percent of Americans 65 and older are still working — the highest level since before

Medicare was established in 1965.

This amounts to almost 9 million workers who are eligible for Medicare — a number that the U.S.

Bureau of Labor Statistics expect to increase about 8,000 baby boomers turn 65 every day until 2030.

Some employers may require employees or covered spouses to enroll in Medicare when they become eligible, so they can

keep their employer-sponsored health insurance. But many workers who are eligible for both types of coverage have to

navigate an array of rules and other considerations regarding costs and coverage.

Primary vs. Secondary Insurance

If an employer has 20 or more employees, the employer coverage is primary and would pay first for covered expenses.

Medicare is secondary and may pay for some expenses not covered by the employer coverage.

If an employer has fewer than 20 employees, Medicare would be primary and the employer coverage would be secondary,

which is why small businesses may require eligible employees or spouses to enroll in Medicare in order to keep their

employer-sponsored coverage.

Part A Hospital Insurance and HSAs

Medicare Part A helps pay for in-patient hospital care as well as a skilled nursing facility, hospice and home health care.

Because Medicare hospital insurance is free for most people, consider enrolling in Part A, even if you have employer

coverage. It could be helpful to have both types of insurance to fill any coverage gaps. However, if you have to pay for Part

A, you may want to wait before enrolling.

If you have a high-deductible health plan through work, keep in mind that you cannot contribute to a health savings account

(HSA) after you enroll in Medicare (A or B). The HSA is yours, even if you can no longer contribute to it, and you can use the

tax-advantaged funds to pay Medicare premiums and other qualified medical expenses. So it might be helpful to build your

HSA balance before enrolling in Medicare.

Should opt out of premium-free Part A in order to contribute to an HSA? That depends on what you consider to be more

valuable: secondary hospital insurance coverage or tax-advantaged contributions to pay future expenses. HSA funds can be

withdrawn free of federal income tax and penalties provided the money is spent on qualified health-care expenses. HSA

contributions and earnings may or may not be subject to state taxes.

Part B and Part D

Medicare Part B medical insurance, which helps pay for physician services and outpatient expenses, requires premium

payments, so it would be wise to compare the costs and benefits of Medicare to your employer’s plan. If you’re satisfied with

your employer coverage, you can generally wait to enroll in Part B. The same is true of Medicare Part D, which helps pay for

prescription drug costs.

Enrollment Periods

Late-enrollment penalties may apply if you do not enroll in Medicare Part A and Part B when you are first eligible. If you are

covered by employer-sponsored health insurance, these penalties generally do not apply as long as you enroll within the

eight-month period that starts the month after the last day of employment or the employer-sponsored health coverage ends

(whichever occurs first).

A late-enrollment penalty for Part D prescription drug coverage may apply if you go 63 or more consecutive days without

having creditable prescription drug coverage. (Most employer plans are considered creditable.) Alternatively, during the two-

month period after your workplace coverage ends, you could enroll in a Part C Medicare Advantage Plan that has

prescription drug coverage.
