How Medicare plan choices in Jamestown compare with nearby New York counties

If you live in Jamestown and want to know how your Medicare choices line up against the counties next door, the 2026 county numbers are the most recent published. The federal Centers for Medicare & Medicaid Services (CMS) sets Medicare Advantage and Part D availability at the county level, so where you live — not just your city — decides what shows up when you shop. The 2027 lineup is spelled out in each plan's Annual Notice of Change (ANOC) and on Medicare.gov's Plan Finder.

Jamestown sits in Chautauqua County, and that is the county whose plan counts apply to local residents. Here is what the 2026 landscape looked like close to home, and how to think about it before the December 7, 2026 deadline for 2027 coverage.

Why county lines matter more than city limits

Medicare Advantage and Part D plans are sold by ZIP code, but the underlying availability is set county by county. That means two neighbors a few miles apart, but in different counties, can see very different lists on Medicare.gov.

For anyone in Jamestown, the relevant county is Chautauqua. If you have family in Cattaraugus, Erie, or Warren County (Pennsylvania), their menu of plans is drawn from a different county file and will not match yours — even if the same carriers show up in both places.

The Jamestown-area snapshot (2026 counts)

Here is what the county-level data shows for Chautauqua County, home to Jamestown:

• Medicare Advantage plans available: 51
• Stand-alone Part D prescription drug plans available: 0
• Carriers offering Medicare Advantage with drug coverage (MA-PD): 8
• Residents age 65 and older: about 26,917

A few things to notice. First, 51 is a healthy number of Medicare Advantage options for a mostly rural county. Second, the stand-alone Part D count listed for the area is 0, which means people who want drug coverage locally will typically find it built into a Medicare Advantage plan rather than as a separate policy. If you have Original Medicare and want a stand-alone Part D plan, talk with a licensed source or your local SHIP counselor about what is offered statewide.

How to compare nearby areas without getting lost

If you're weighing options across county lines — maybe because you split time between homes, or you're helping a parent in another county — the cleanest approach is to compare counts, not names, first.

• Look up each county on Medicare.gov's Plan Finder by ZIP code.
• Note how many Medicare Advantage plans and how many carriers appear.
• Then narrow by what matters to you personally: your doctors, your prescriptions, and your pharmacy.

Plan counts alone don't tell you which plan fits. But they do tell you how much choice you have to work with. A county with dozens of Medicare Advantage plans and multiple carriers gives you more room to match a plan to your doctors and drug list than a county with only a few.

Star Ratings, briefly

CMS publishes Star Ratings that measure plan quality on a 1-to-5 scale. In the Chautauqua County data block for 2026, 0 contracts in the area were rated 4 stars or higher. Ratings can change year to year, and they are one input among many — not a substitute for checking whether your own doctors and medications are covered.

What's new for 2027 across the board

Some things are the same no matter which nearby county you live in:

• The Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027. Once your covered drug spending hits that ceiling, you pay nothing for covered drugs the rest of the year.
• The Part D deductible can be no higher than $615 in 2026 and $700 in 2027.
• The old "donut hole" coverage gap is gone. Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the calendar year in monthly installments instead of paying at the pharmacy counter.
• Income-related monthly adjustment amounts (IRMAA) for Part B and Part D begin above $109,000 in income for a single filer in 2026.

Dates to circle

• October 15 – December 7: Annual Enrollment Period. Anyone with Medicare can join, switch, or drop a Medicare Advantage or Part D plan.
• January 1 – March 31: Medicare Advantage Open Enrollment Period. If you're already in a Medicare Advantage plan on January 1, you get one chance to switch to another Medicare Advantage plan or return to Original Medicare (and add a Part D plan).
