Medicare in Fairfield: 101 Advantage plans, 15 carriers for 2026

FAIRFIELD, Ohio — If you're sorting through Medicare choices in Butler County this fall, the sheer number of options can feel like a lot. Butler County had 101 Medicare Advantage plans from 15 carriers for 2026; the 2027 lineup is spelled out in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder. But the number that may matter more to your wallet isn't the plan count — it's how Medicare's cost pieces fit together, starting with the Part D out-of-pocket cap, which is $2,100 in 2026 and $2,400 in 2027.

Here's a plain-English look at how the program's cost structure is shifting into 2027, so you can size up your options in Fairfield with clearer eyes.

The cost pieces heading into 2027, in order

Medicare isn't one bill. It's a stack of them, and each part has its own cost rules set by the federal government:

• Part A (hospital): Most people pay no premium because they or a spouse paid Medicare taxes long enough while working. Part A still has its own deductible when you're admitted.
• Part B (doctors and outpatient): Has a standard monthly premium and an annual deductible, both set nationally by CMS each year.
• Part D (prescription drugs): Premiums vary by plan, but the deductible cannot exceed $615 in 2026, and your total out-of-pocket for covered drugs is capped at $2,100.
• Medicare Advantage (Part C): Bundles A, B and usually D into one plan from a private carrier. You still owe your Part B premium, plus whatever the plan charges.
• Medigap (Medicare Supplement): An optional policy that pairs with Original Medicare to help cover deductibles and coinsurance. It carries its own separate premium.

Fairfield sits in Butler County, where all 101 Medicare Advantage plans in the 2026 landscape bundled drug coverage, and 0 stand-alone Part D plans were available in the area for 2026 — a pattern that makes the MA-versus-Original-Medicare-plus-Medigap decision especially important locally. The 2027 lineup is listed in each plan's ANOC and on Medicare.gov's Plan Finder.

What the $2,100 Part D cap actually does

Starting in 2026, once your out-of-pocket spending on covered prescription drugs hits $2,100, you pay $0 for the rest of the calendar year on those drugs. This cap applies whether your Part D coverage comes through a stand-alone plan or is built into a Medicare Advantage plan.

Two other pieces work alongside the cap:

1. The deductible phase. Your plan may charge a deductible before cost-sharing kicks in. The maximum is $615 in 2026 and $700 in 2027, though individual plans can set theirs lower. 2. The Medicare Prescription Payment Plan. This is a free, optional program that lets you spread your yearly drug costs across monthly payments instead of paying big amounts at the pharmacy counter. It doesn't change what you owe — just when you owe it.

And as of 2025, the old "donut hole" coverage gap is gone. Part D now has three phases: deductible, initial coverage, and catastrophic (where you hit that $2,100 ceiling).

Where higher-income rules come in

If your income is above certain thresholds, you'll pay more for Part B and Part D through a surcharge called IRMAA (Income-Related Monthly Adjustment Amount). For 2026, IRMAA begins above $109,000 for a single filer (higher for joint filers). Social Security uses your tax return from two years ago to decide.

If your income has dropped since then — for example, because you retired — you can ask Social Security to reconsider using a life-changing event form.

Comparing costs among 101 plans without getting lost

With 101 Medicare Advantage plans in Butler County and 15 carriers competing, cost comparisons take a little discipline. A few honest, program-level pointers:

• Look at the total of premium + deductible + expected cost-sharing for your prescriptions and doctors, not just the monthly premium.
• Check whether your regular medications land in a tier the plan actually covers.
• Make sure your doctors and preferred hospitals are in-network.
• Remember Star Ratings exist to give you a general sense of a plan's quality and member experience. They're one input among several.

The official Medicare Plan Finder at medicare.gov lets you enter your ZIP code and medications and see plans side-by-side. It's the same data licensed agents work from.

Dates to keep on your calendar

• October 15 – December 7: Annual Enrollment Period. You can join, switch or drop a Medicare Advantage or Part D plan for coverage starting January 1.
• January 1 – March 31: Medicare Advantage Open Enrollment. If you're already in a Medicare Advantage plan, you get one chance to switch to another MA plan or return to Original Medicare.

Missing these windows can mean waiting a full year — or, for Part D, facing a late-enrollment penalty that follows you for life.
