Spring is here—and for many Southwest Montana residents, April is the time when Medicare questions start bubbling up. Maybe you’re approaching 65 and realizing enrollment is closer than you thought. Maybe you’re already on Medicare but wondering if your current plan is still the right fit. Or maybe someone in your family just retired and suddenly Medicare feels urgent.
At Nye Insurance Agency—locally owned and operated—we help people in Dillon, MT and the surrounding area navigate Medicare with confidence. Whether you’re a rancher, a retiree, or a longtime Dillon resident approaching 65, navigating Medicare in rural Montana comes with its own set of considerations—especially when it comes to finding plans that include your preferred doctors and local providers.
This blog is your April Medicare primer: what Medicare is, what the different parts cover, when you can enroll, and how to avoid the costly mistakes we see people make every year.
Medicare 101: A Quick Refresher
Medicare is the federal health insurance program for people 65 and older, as well as for certain younger people with disabilities or specific medical conditions. It’s divided into distinct parts, each covering different aspects of your healthcare:
Part A — Hospital Insurance
Part A covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health services. Most people don’t pay a premium for Part A if they or their spouse paid Medicare taxes for at least 10 years (40 quarters) while working.
Part B — Medical Insurance
Part B covers outpatient care, doctor visits, preventive services, and medically necessary services and supplies. In 2026, the standard Part B premium is $202.90 per month. Unlike Part A, Part B requires you to actively enroll—and if you miss your window, you may face a permanent late enrollment penalty.
Part C — Medicare Advantage
Medicare Advantage plans are offered by private insurance companies approved by Medicare. They bundle Parts A and B—and usually Part D—into a single plan. Many plans include additional benefits like dental, vision, and hearing coverage. However, Advantage plans typically have a provider network, so it’s important to confirm your doctors are in-network before enrolling.
Part D — Prescription Drug Coverage
Part D covers prescription medications and is available as a standalone plan (used alongside Original Medicare) or bundled within a Medicare Advantage plan. In 2025, Part D out-of-pocket drug costs are capped at $2,000 for the year—a major benefit for people on multiple medications. Skipping Part D when you first become eligible can result in a permanent penalty if you go without creditable drug coverage.
Medicare Supplement (Medigap)
Medigap plans are sold by private insurers and designed to fill the gaps that Original Medicare leaves behind—like deductibles, copayments, and coinsurance. Unlike Medicare Advantage, Medigap works alongside Original Medicare (Parts A and B) and typically allows you to see any provider that accepts Medicare, nationwide. The best time to buy a Medigap plan is during your 6-month Medigap Open Enrollment Period, which begins the month you turn 65 and are enrolled in Part B.
Medicare Enrollment Periods: When Can You Act?
One of the most important—and most misunderstood—aspects of Medicare is knowing when you can enroll or make changes. Here’s a breakdown of the key windows:
Initial Enrollment Period (IEP)
Your IEP is a 7-month window that begins 3 months before your 65th birthday month, includes your birthday month, and extends 3 months after. This is your first and most important opportunity to sign up for Medicare without penalty. If your birthday is in April, your IEP runs from January through July—meaning the clock may already be ticking.
Special Enrollment Period (SEP)
If you delayed Medicare because you were covered by an employer’s health plan, you qualify for a Special Enrollment Period when that coverage ends. You typically have 8 months to enroll in Part B without penalty after your employer coverage ends. Life events—like moving out of your plan’s service area, losing coverage, or qualifying for Extra Help with drug costs—can also trigger an SEP.
Annual Enrollment Period (AEP) — Oct. 15 to Dec. 7
The AEP is the main window each year when existing Medicare beneficiaries can make changes to their coverage: switching between Original Medicare and Medicare Advantage, changing Part D drug plans, or adding/dropping coverage. Changes made during AEP take effect January 1 of the following year.
Medicare Advantage Open Enrollment Period (MA-OEP) — Jan. 1 to Mar. 31
If you’re already enrolled in a Medicare Advantage plan, you can make one change between January 1 and March 31 each year—either switching to a different Advantage plan or returning to Original Medicare. This window has now closed for 2025, making it especially important to review your options carefully before next year’s AEP.
Why April Is the Right Time to Think About Medicare
While Medicare’s main enrollment window is in the fall, April is actually a strategically important month for several reasons:
- Turning 65 this summer? If your birthday is in July, your Initial Enrollment Period starts in April. Don’t wait until your birthday—enrolling in the first three months of your IEP ensures coverage starts on time.
- Retiring in the next few months? If you’re leaving employer coverage this spring or summer, now is the time to understand your Special Enrollment Period and how to transition to Medicare without a gap.
- Already on Medicare? April is a good time to review your current plan and flag any issues—doctor network changes, new prescriptions, or rising costs—before the fall enrollment window.
- Turning 65 later this year? Even if your IEP hasn’t started yet, April is an ideal time to meet with a local Medicare agent, compare plan types, and come to your enrollment window fully informed.
- Recently experienced a qualifying life event? A move, a change in Medicaid eligibility, or loss of other coverage may have triggered a Special Enrollment Period you haven’t acted on yet.
Common Medicare Mistakes to Avoid
These are the mistakes we see most often—and every one of them is avoidable with the right guidance:
- Missing Part B enrollment: Many people assume they’ll be automatically enrolled. If you’re not receiving Social Security benefits, you must sign up manually. Missing the window means waiting until the General Enrollment Period (Jan.–Mar.) and paying a 10% premium penalty for each year you delayed.
- Skipping Part D: Even if you’re healthy and take no medications, going without creditable prescription drug coverage for more than 63 days after your IEP ends can result in a permanent Part D penalty.
- Assuming your employer retiree coverage is “creditable”: Some retiree plans do not qualify as creditable coverage for Medicare purposes. Always verify before assuming you’re protected.
- Not comparing plans annually: Medicare plans change every year. A plan that was a great fit last year may have different premiums, formularies, or provider networks this year.
- Missing the Medigap Open Enrollment window: This 6-month window (starting the month you turn 65 and enroll in Part B) is the only time you can buy any Medigap policy without medical underwriting. Missing it can make Medigap harder—or impossible—to obtain later.
Original Medicare vs. Medicare Advantage: Which Is Right for You?
One of the most common questions we get is whether to go with Original Medicare (Parts A and B, possibly with a Medigap plan and Part D) or a Medicare Advantage plan. There’s no universal right answer—it depends on your health, your budget, and your priorities.
Original Medicare + Medigap + Part D offers broad provider access (any doctor that accepts Medicare nationwide), more predictable out-of-pocket costs, and no network restrictions. It tends to work well for people who travel frequently, have complex health needs, or value flexibility above all else.
Medicare Advantage can offer lower monthly premiums and additional benefits like dental, vision, and hearing. However, you’re typically restricted to a provider network, and out-of-pocket costs can be higher if you need significant care. Plans vary significantly by region and carrier, so local availability matters.
The best way to make this decision is to sit down with an independent Medicare agent who can show you what’s actually available in your area and walk through the numbers with you based on your specific situation.
Don’t Overlook Your Free Medicare Preventive Benefits
One of the most underused parts of Medicare is the suite of free preventive services included under Part B. Once you’re enrolled, you’re entitled to a range of no-cost screenings and check-ups, including:
- Annual Wellness Visit (once per year at no cost)
- Cardiovascular disease screenings
- Cancer screenings (colorectal, breast, cervical, prostate)
- Diabetes screenings and diabetes self-management programs
- Depression screenings
- Bone density tests
- Flu, pneumonia, and COVID-19 vaccines
Taking advantage of these benefits costs you nothing and can catch health issues early—when they’re much easier and less expensive to treat. If you’re not sure what’s covered under your plan, ask us.
