Medicare Supplement (Medigap) in Leominster, Massachusetts: A Clear 2027 Guide

Around 147,690 people in Worcester County are 65 or older — many of whom pair Original Medicare with a Medigap policy for predictable costs. For anyone in Leominster, Massachusetts, this 2027 guide explains the standardized plans and what each covers.

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

There, 50 Medicare Advantage plans are available for 2027. Roughly 45% of people with Medicare in the county have chosen Medicare Advantage over Original Medicare, among the roughly 147,690 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.

Where Medigap fits in your Medicare

Original Medicare (Part A and Part B) pays most of your covered costs — but not all. You're left with deductibles, coinsurance, and copays, and there's no annual out-of-pocket maximum in Original Medicare on its own. That open-ended exposure is the gap Medigap policies are designed to help close.

Medigap policies are sold by private insurers but standardized by the federal government and labeled with letters (such as Plan G or Plan N). Because they're standardized, a given lettered plan covers the same things no matter who sells it — what differs is price and service. Medigap pairs with Original Medicare, not Medicare Advantage, and doesn't include drugs, so people on this path usually add a stand-alone Part D plan.

This guide explains how the standardized plans and your enrollment rights work in Leominster, Massachusetts. We explain the framework — we don't rank plans or quote specific premiums.

What Medicare costs in 2027

It helps to separate the costs everyone shares from the costs that vary by plan. The program-level numbers here are set nationally — the same whether you're in a big city or a rural county.

Part B premium. Most people pay the standard Part B premium of $202.90 a month in 2026 (2026 amount; 2027 figure will be posted when CMS releases it). Part A is premium-free for most people who worked and paid Medicare taxes long enough.

Part D drug costs. In 2027, a Part D plan's yearly deductible can be no more than $700, and a $2,400 cap limits what you pay out of pocket for covered prescriptions across the year — a real change for anyone with high drug costs.

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.

Plan-specific costs. What an individual plan charges — its premium, deductible, copays, and what it covers — varies by plan and changes yearly. We don't publish those figures or rank plans; Medicare's Plan Finder shows the current details for your situation, and a licensed agent can walk you through them.

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, 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.
