Still on the Job at 65? How to Time Medicare in Twin Falls

# Still on the Job at 65? How to Time Medicare in Twin…

If you're approaching 65 in Twin Falls and still clocking in at work, you may be wondering whether you need to sign up for Medicare right away — or whether your job's health plan is enough for now. The answer depends on the size of your employer, how your current coverage works, and a few deadlines that are easy to miss. Here's a plain-language guide to help you decide.

Start with Part A — it's usually the easy call

Most people qualify for premium-free Part A (hospital insurance) at 65 because they or a spouse paid Medicare taxes long enough while working. Because there's no monthly premium for most folks, signing up for Part A at 65 is often a no-brainer, even if you keep your job coverage.

One important exception: if you contribute to a Health Savings Account (HSA), you and your employer must stop those contributions once you enroll in any part of Medicare, including Part A. If your HSA is a big part of your benefits, talk with your HR department before you enroll.

Part B depends on the size of your employer

This is where the size of the company you work for really matters.

• 20 or more employees: Your employer's group health plan usually pays first, and Medicare pays second. You can generally delay Part B without a late penalty and pick it up later, when you retire or lose the coverage.
• Fewer than 20 employees: Medicare usually pays first, and your employer plan pays second. If you don't sign up for Part B at 65, you could be left with big gaps in coverage — and face a lifelong late-enrollment penalty later.

If you're not sure which category your employer falls into, ask your benefits administrator in writing. This is the single most important question to answer before your 65th birthday.

Watch the Special Enrollment Period after you retire

When you eventually leave your job (or lose the group coverage), you get an 8-month Special Enrollment Period to sign up for Part B without a penalty. That window starts the month after your employment or your group coverage ends, whichever comes first.

COBRA and retiree coverage do not count as active employer coverage for this rule. If you go on COBRA after leaving your job, the Medicare clock still runs. Many people find that out the hard way — don't be one of them.

Don't forget about Part D drug coverage

If your employer plan includes prescription drug coverage that Medicare considers "creditable" (meaning at least as good as a standard Medicare drug plan), you can delay Part D without a penalty. Your plan should send you a notice each year telling you whether your drug coverage is creditable. Save that letter.

Heading into 2027, Medicare's Part D program has some notable features worth knowing:

• An annual out-of-pocket cap on covered prescriptions of $2,100 in 2026 and $2,400 in 2027.
• A maximum Part D deductible of $615 in 2026 and $700 in 2027.
• The old coverage gap ("donut hole") is gone as of 2025, replaced by a simpler three-phase structure.
• An optional Medicare Prescription Payment Plan lets you spread drug costs across the calendar year in monthly installments.

Higher earners should also be aware of IRMAA — the income-related surcharge that adds to Part B and Part D premiums. For 2026, it starts above $109,000 in income for a single filer.

What's available around Twin Falls

Twin Falls is in Twin Falls County, where Medicare Advantage and Part D plan availability is set at the county level. If and when you're ready to compare what's offered — either now or after you leave your job — the plan finder at medicare.gov lets you search by ZIP code and see every option available in your county, along with each plan's Star Rating and coverage details.

If you'd rather talk with someone locally, Idaho's State Health Insurance Assistance Program (SHIP), called Senior Health Insurance Benefits Advisors (SHIBA), offers free, unbiased counseling. It's not a sales operation — the counselors don't earn commissions.

A simple decision checklist

Before your 65th birthday, work through these questions:

1. Does my employer have 20 or more employees? 2. Is my drug coverage creditable (get it in writing)? 3. Do I contribute to an HSA that I'd have to stop? 4. When I leave this job, will I remember the 8-month Part B window? 5. Have I compared what my employer plan actually costs me versus what Medicare would cost?

If your job plan has high premiums or thin benefits, Medicare might make sense even while you're working. If it's strong coverage from a big employer, delaying can be perfectly reasonable.
