Prescription Coverage in Ohio: A 2027 Medicare Part D 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 Ohio should know — no jargon, no sales pitch.

One fact shapes every Medicare decision in Ohio: your county, not your state, sets your options. Neighboring counties can look surprisingly different, which is exactly why the guides here are local.

About 57% across Ohio have chosen Medicare Advantage over Original Medicare, though that share swings a lot depending on where you live.

Ahead: the companies active statewide, how Original Medicare, Advantage, Medigap and Part D fit together, the shared 2027 costs, enrollment windows, free unbiased help, and a guide for every Ohio city.

Part D, phase by phase

Part D is Medicare's prescription-drug coverage, and you can get it either on its own alongside Original Medicare or baked into a Medicare Advantage plan. The government sets the structure; private insurers run the plans.

Here's the shape of a 2027 plan: you first pay a deductible (capped at $700), then share costs during initial coverage, and finally hit a catastrophic phase where a new yearly out-of-pocket cap kicks in — the old coverage gap has been eliminated. If lumpy pharmacy bills are a worry, the Medicare Prescription Payment Plan can spread them monthly.

We explain how all of that plays out in Ohio. Because each plan's drug list and pricing differ, the plan-specific details belong on Medicare's Plan Finder — we don't rank plans.

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.

Your Medicare enrollment calendar

The dates that follow are set federally, so they don't change from state to state — only your personal timing does.

It starts with your Initial Enrollment Period — the 7-month window around your 65th birthday month — the window around turning 65 when you first sign up. Missing it can mean late penalties that stick around, so it's the one not to sleep on.

After that, the big recurring window is the Annual Enrollment Period (Open Enrollment), October 15 – December 7, when anyone can join, switch, or drop an Advantage or Part D plan for a January 1 start. And if you're already in an Advantage plan, the Medicare Advantage Open Enrollment (January 1 – March 31) gives you one more chance to change course.

Life events — a move, a loss of other coverage — can also trigger a Special Enrollment Period. The calendar below shows the whole year at a glance.
