Medicare Part D

How Medicare Fits With Job Coverage in Cheyenne

CHEYENNE, Wyo. — More people are staying on the job past 65, and that's raising the same question at kitchen tables across Laramie County: if you already have health insurance through work, do you need to sign up for Medicare right now?

The honest answer is it depends — on the size of your employer, the kind of coverage you have, and a few deadlines that can quietly cost you if you miss them. Here's a plain-English guide to sorting it out.

Start with the size of your employer

Medicare's rules hinge on how many people work where you do.

• 20 or more employees: Your job's group health plan usually pays first, and Medicare pays second if you enroll. Many workers in this situation delay Part B to avoid paying a second premium.
• Fewer than 20 employees: Medicare typically pays first. That means if you don't enroll in Part B when you're first eligible, your employer plan may cover very little — leaving you exposed. Talk to your HR or benefits office before your 65th birthday.

This is one of the most common places people get tripped up, so it's worth a direct conversation with your employer, not a guess.

Part A is usually an easy call

Most people qualify for premium-free Part A (hospital insurance) because they or a spouse paid Medicare taxes long enough. If that's you, signing up at 65 usually makes sense — it can work alongside employer coverage without an extra premium.

One exception: if you contribute to a Health Savings Account (HSA), you can't keep adding money to it once you enroll in any part of Medicare, including Part A. Some workers choose to delay Part A for that reason. Check with your benefits team.

Part B is where timing really matters

Part B (doctor visits and outpatient care) carries a monthly premium, so many people with strong employer coverage delay it. That can be fine — if your employer plan counts as "creditable coverage" based on active employment.

When you eventually leave the job or lose that coverage, you get an 8-month Special Enrollment Period to sign up for Part B without a late penalty. Miss that window, and you could face a lifetime premium surcharge and gaps in coverage.

Ask HR for something in writing confirming your coverage is based on current employment. You'll want that record.

Don't forget prescription drugs

If your employer plan includes drug coverage that's considered "creditable" (at least as good as Medicare's), you can usually delay Part D without a penalty. Your plan should send you a notice each year telling you whether your drug coverage qualifies. Save that letter.

A few Part D facts worth knowing when you do eventually enroll:

• The annual out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027 — once you hit that, you pay nothing for covered drugs the rest of the year.
• The maximum deductible is $615 in 2026 and $700 in 2027.
• The old "donut hole" coverage gap has been eliminated since 2025; the program now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs into monthly payments instead of paying all at once at the pharmacy.

What's available around Cheyenne

Cheyenne is in Laramie County, where Medicare Advantage and stand-alone Part D plan options are set at the county level by the Centers for Medicare & Medicaid Services (CMS). If and when you're ready to compare plans, the official Plan Finder at Medicare.gov shows every plan available in your ZIP code, along with drug lists, pharmacy networks, and Star Ratings (CMS's quality measure).

Star Ratings can help you evaluate a plan's track record, but they aren't a substitute for checking that your doctors, hospitals, and medications are covered.

Watch these dates

• Initial Enrollment Period: The 7 months around your 65th birthday (3 before, the month of, 3 after).
• Special Enrollment Period: Up to 8 months after employer coverage ends, for Part B.
• Annual Enrollment Period: Oct. 15 – Dec. 7 each year, for Part D and Medicare Advantage changes.
• Medicare Advantage Open Enrollment: Jan. 1 – March 31, if you're already in an Advantage plan and want to switch.

Higher earners should also know that IRMAA — an income-related surcharge on Part B and Part D premiums — begins above $109,000 in income for single filers in 2026 (higher for joint filers).
