Q&A: Medicare vs. spouse’s health plan

Dear Liz: I am planning to retire in a few months at 65. My husband, who is five years younger, works for a corporation that provides excellent health insurance. When I sign up for Medicare, will I still be able to stay on my husband’s health insurance? Which insurance will be listed first for coverage?

Answer: The rules are different depending on whether your husband’s insurance is considered a large employer plan or a small employer plan.

If the plan covers 20 or fewer employees, his employer can boot you off the plan or make it secondary to Medicare. If the plan covers more than 20 employees, though, the employer typically can’t treat you differently from younger employees and spouses and must allow you to stay on the plan, which would remain your primary insurance with Medicare as the secondary insurer.

Medicare penalties are another issue to consider. Medicare Part A, which covers hospital visits, is usually premium-free, but people generally pay premiums for Medicare Part B, which covers doctor’s visits, and Medicare Part D, which covers prescription drugs. If you don’t sign up for Medicare Part B and Part D when you’re first eligible, you could face permanent penalties that would raise your monthly premiums for life.

These penalties don’t apply if you put off signing up for Part B and Part D because you’re covered by a large employer health insurance plan from current employment, either yours or your spouse’s. Once that employment or coverage ends, though, you’ll need to sign up for Part B and Part D promptly or the penalties kick in.

Notice the use of the words “typically,” “normally” and “generally” in the paragraphs above. Medicare’s rules and exceptions can be tricky to navigate. Talk to the benefits manager at your husband’s company so you know where you stand, and what parts of Medicare to sign up for as you turn 65.

    And you wonder why I have real bad dreams of waking up in America. I have national health care in Australia.

  2. Liz, both Medicare, our primary insurance and two brokers have told me that Medicare always pays first with a small employer (under 20). It is not something that an employer can decide.
