Medicare Part D in Peoria, Illinois: Your 2027 Prescription Coverage Guide

Drug coverage under Medicare got a major overhaul for 2027. This guide covers the $2,400 out-of-pocket cap, how the coverage phases work, and what people in Peoria, Illinois should know — no jargon, no sales pitch.

New to Medicare around Peoria? Start with one fact that clears up a lot of confusion: what's available to you is decided at the county level, and Peoria falls in Peoria County (part of Peoria area).

There, 25 Medicare Advantage plans are available for 2027. Roughly 51% of people with Medicare in the county have chosen Medicare Advantage over Original Medicare, among the roughly 32,813 residents who are 65 or older.

Below, we lay out the carriers serving the area, how Original Medicare, Advantage, Medigap and Part D relate, the 2027 numbers everyone shares, the enrollment calendar, and free help — all educational, with no plan rankings.

How Part D drug coverage works

Medicare Part D covers prescription drugs. You can get it two ways: as a stand-alone plan added to Original Medicare, or built into a Medicare Advantage plan that includes drug coverage. Either way, the basic structure is set by Medicare and the plans are run by private insurers.

For 2027, coverage moves through three phases — a deductible phase (no more than $700), an initial coverage phase, then a catastrophic phase. The old 'donut hole' gap is gone, and an annual out-of-pocket cap limits what you pay for covered drugs. An optional Medicare Prescription Payment Plan also lets you spread those costs across the year.

This guide explains those rules as they apply in Peoria, Illinois. Specific drug lists and pricing vary by plan, so for plan-by-plan detail we point you to Medicare's Plan Finder rather than ranking plans ourselves.

The 2027 numbers, from shared to plan-specific

Start with what's fixed for everyone. The standard Part B premium is $202.90 per month in 2026 (2026 amount; 2027 figure will be posted when CMS releases it), and Part A is premium-free for most people who paid Medicare taxes long enough while working.

On the drug side, Part D has real guardrails for 2027: a deductible capped at $700 and, a hard $2,400 ceiling on your out-of-pocket costs for covered prescriptions — the old coverage gap is gone.

Higher earners pay more for Parts B and D through an income-related adjustment called IRMAA, which for 2026 starts above $109,000 in annual income for an individual and is based on your 2024 tax return. Most people fall below that line and pay the standard amounts. The 2027 brackets will be posted when CMS releases them.

Everything past that is plan-specific: the premiums, copays, and coverage details of an individual Advantage or Medigap plan change from plan to plan and year to year. Rather than quote or rank those, we point you to Medicare's Plan Finder and a licensed agent for your exact numbers.

When you can enroll or make changes

Medicare's enrollment windows are federal — the same nationwide — so the timing below applies wherever you live.

Your first window (IEP). When you're new to Medicare, your Initial Enrollment Period is the 7-month window around your 65th birthday month. Signing up on time helps you avoid late penalties that can follow you for years.

Annual Enrollment Period (AEP). Each fall, from October 15 – December 7, anyone with Medicare can join, switch, or drop a Medicare Advantage or Part D plan. Changes take effect January 1.

Medicare Advantage Open Enrollment. From January 1 – March 31, if you're already in an Advantage plan you get one chance to switch plans or return to Original Medicare.

Special Enrollment Periods can also open after certain life events, like moving or losing other coverage. The interactive calendar further down lays the year out visually.
