Medicare and Your Job: When to Enroll If You're Still Working

ENID, Okla. — Turning 65 while still clocking in? You're not alone. Many people in Enid keep working past 65 for the paycheck, the health coverage, or simply because they love what they do. The question is what to do about Medicare — sign up now, wait, or piece the two together.

Getting this decision right matters. The wrong move can mean gaps in coverage or a lifelong penalty. The good news: once you know how Medicare and job-based insurance fit together, the choice usually gets simpler.

Start with your Initial Enrollment Period

Your first chance to sign up for Medicare is a seven-month window around your 65th birthday — the three months before, your birthday month, and the three months after. This is called your Initial Enrollment Period (IEP).

Even if you plan to keep working, it's worth marking this window on the calendar. Missing it without qualifying coverage from a job can lead to late penalties that stick with you for as long as you have Medicare.

The employer size rule that changes everything

Whether you can safely delay Medicare depends largely on how many people work at your employer.

• 20 or more employees: Your job-based plan usually pays first, and Medicare would pay second. You can often delay Part B without a penalty as long as you have this coverage.
• Fewer than 20 employees: Medicare typically pays first. In this case, most people should enroll in Part A and Part B at 65, because the employer plan may only cover what Medicare doesn't.

If you're not sure which category your employer falls into, ask your HR or benefits office in writing. Don't guess — this one detail can change your whole strategy.

Part A is usually a yes. Part B is the real question.

Most people qualify for premium-free Part A (hospital coverage) because they paid Medicare taxes while working. If that's you, signing up for Part A at 65 is often a simple decision.

One important exception: if you contribute to a Health Savings Account (HSA), you and your employer must stop contributing once Medicare — including Part A — begins. You can still spend what's already in the HSA.

Part B (doctor visits and outpatient care) has a monthly premium, so many workers with strong employer coverage choose to delay it. Just make sure your employer plan qualifies as "creditable" primary coverage before you skip Part B.

Special Enrollment Period: your safety net when you retire

When you eventually leave your job or lose employer coverage, you get a Special Enrollment Period (SEP) to sign up for Part B without a late penalty. This SEP lasts up to eight months after your employment or coverage ends — whichever comes first.

A common mistake: assuming COBRA or retiree coverage counts as active employer coverage for Medicare. It doesn't. Once your active job-based coverage ends, the clock starts, even if COBRA continues.

Don't forget prescription drugs

Part D covers prescriptions, and it has its own late-enrollment penalty. If your job's drug coverage is "creditable" (at least as good as Medicare's), you can delay Part D without penalty. Employers are required to send a notice each year telling you whether your drug coverage is creditable — keep those letters.

For 2026, Medicare's Part D benefit includes a $2,100 annual out-of-pocket cap on covered drugs, a maximum deductible of $615, and the option to spread drug costs across the year through the Medicare Prescription Payment Plan. The old coverage gap ("donut hole") is gone as of 2025.

What's available around Enid

Enid is in Garfield County, where Medicare Advantage and Part D plans are offered through several private carriers approved by Medicare. Plan counts and options are set at the county level and can change each year, so it's worth checking medicare.gov's plan finder during the fall to see what's available for the coming year — especially if you're getting close to retiring.
