Turning 65 in Lafayette? Your 2027 Medicare Cost Guide

Turning 65 in Lafayette? Here's how Medicare's costs fit together as you choose 2027 coverage.

LAFAYETTE, La. — If you're approaching 65 here in Acadiana, one of the first things you'll want to sort out isn't which plan to pick. It's how Medicare's cost pieces actually fit together. Once you understand the moving parts — premiums, deductibles, and the new out-of-pocket cap — the choices in front of you get a lot less overwhelming.

Lafayette sits in Lafayette Parish, where 49 Medicare Advantage plans were available for 2026, offered by 7 carriers. The 2027 lineup is in each plan's ANOC and on Medicare.gov's Plan Finder. That's plenty of options, but the smarter starting point is learning how the program itself charges you, no matter which path you take.

Start with the parts, then the price tags

Medicare has four parts, and each carries its own cost logic:

• Part A (hospital) is premium-free for most people who paid Medicare taxes long enough. It has its own deductible per benefit period.
• Part B (doctor and outpatient) has a standard monthly premium set each year by CMS, plus an annual deductible and 20% coinsurance for most services.
• Part C (Medicare Advantage) bundles A and B — and usually D — through a private carrier. You still owe your Part B premium.
• Part D (prescription drugs) is either stand-alone or built into an Advantage plan.

Knowing which bucket a cost falls into is half the battle. A hospital bill runs through Part A rules; an MRI runs through Part B; your blood pressure pill runs through Part D.

The Part D cost cap is the biggest recent shift

For years, the scariest part of Medicare drug coverage was the open-ended risk. A single expensive prescription could mean thousands of dollars a year with no ceiling. That's changed.

In 2027, Part D out-of-pocket costs are capped at $2,400 (up from $2,100 in 2026). Once you hit that number in a calendar year, you pay $0 for covered drugs the rest of the year. The maximum Part D deductible is $700 in 2027 (it was $615 in 2026), though many plans set theirs lower.

The coverage gap — the "donut hole" — was eliminated in 2025. Part D now moves through three phases: deductible, initial coverage, and catastrophic (where the cap kicks in).

If paying that $2,100 in 2026 ($2,400 in 2027) all at once would strain your budget, there's also the Medicare Prescription Payment Plan, an optional program that spreads your drug costs into smoother monthly payments across the year. You don't pay more overall — you just even out the timing.

Part B and the income question (IRMAA)

Most people pay the standard Part B premium. But if your income is higher, you'll pay an Income-Related Monthly Adjustment Amount (IRMAA) on top of both Part B and Part D.

For 2026, IRMAA starts above $109,000 in income for a single filer (higher thresholds apply for joint filers). Social Security uses your tax return from two years back to decide. If your income has dropped since then — say, because you retired — you can ask for a reconsideration using Form SSA-44.

Where Medicare Advantage changes the math

Choosing Medicare Advantage doesn't erase your Part B premium — you still pay it. What changes is how the rest is structured. Advantage plans set their own deductibles, copays, and an annual maximum out-of-pocket limit for medical services (separate from the Part D drug cap). Original Medicare, by contrast, has no annual out-of-pocket cap on medical costs, which is why many people pair it with a Medigap policy.

That trade-off — a network with a built-in ceiling versus broader access with supplemental coverage — is really a cost-structure decision. In Lafayette Parish, 49 Advantage plans from 7 carriers were offered for 2026, and the 2027 lineup is in each plan's ANOC and on Medicare.gov's Plan Finder, giving you room to compare — but the comparison only makes sense once you know what you'd owe under each model.

Dates you can't miss

• Initial Enrollment Period: The 7 months around your 65th birthday (3 before, the month of, 3 after). Missing it can mean lifetime late-enrollment penalties on Part B and Part D.
• Annual Enrollment Period: October 15 – December 7, when anyone with Medicare can change plans for the following year.
• Medicare Advantage Open Enrollment: January 1 – March 31, a narrower window if you're already in an Advantage plan and want to switch or drop back to Original Medicare.
