Medicare Advantage

Already in Advantage? You have until March 31 to switch

Cook County has 67 Medicare Advantage plans for 2027. Compared with 2026, 17 plans are not coming back, 6 are new, and 30 continuing plans changed in some way you should check before December 7, 9 of them under a new name. This guide covers what those numbers mean for Hoffman Estates, not which plan to pick.

Hoffman Estates, Ill. — If January's first Medicare Advantage bill or pharmacy visit left you wondering whether you picked the right plan, take a breath. From January 1 through March 31, people already enrolled in a Medicare Advantage plan get a second look — a chance to make one change without waiting until next fall. It's called the Medicare Advantage Open Enrollment Period, and it exists precisely for the "wait, this isn't what I expected" moment.

Who this window is actually for

This period is designed for one group: people who are already enrolled in a Medicare Advantage plan as of January 1. If that's you, and something about your plan isn't working — a doctor left the network, a prescription is costing more than you expected, or the plan simply feels like the wrong fit — you have until March 31 to adjust course.

If you're still on Original Medicare only, this window is not for you. You'd generally need to wait for the fall Annual Enrollment Period or qualify for a Special Enrollment Period.

What you can change (and what you can't)

During January 1 – March 31, you're allowed one change. Your options are:

• Switch to a different Medicare Advantage plan. This can be with or without drug coverage, depending on what's available.
• Leave Medicare Advantage and go back to Original Medicare. If you do this, you can also join a stand-alone Part D prescription drug plan.

What you cannot do in this window:

• Join a Medicare Advantage plan for the first time if you started the year on Original Medicare.
• Switch from one stand-alone Part D drug plan to another (that's a fall-only move for most people).
• Make multiple changes. Once you use this window, it's used.

Any change you make takes effect the first day of the following month.

How to decide if a change is worth making

Before switching, it helps to slow down and look at the plan you have now with fresh eyes. A few questions worth asking:

• Are my regular doctors and preferred hospitals still in-network for 2027?
• Are my prescriptions still on the plan's drug list, and at a tier I can afford?
• Have my health needs changed — new diagnosis, new specialist, new medication?
• Does the plan still cover the extras I actually use, versus the ones that sounded nice on paper?

If the answers line up, staying put is a perfectly valid choice. If not, you have time to compare.

Local context for Hoffman Estates

Hoffman Estates is in Cook County, where Medicare beneficiaries generally have a wide range of Medicare Advantage and Part D options to compare. Because plan availability, provider networks, and drug lists are set at the county level, the specifics of what's offered near you will look different from a neighbor in another part of Illinois. The Medicare Plan Finder at Medicare.gov lets you enter your ZIP code and your medication list to see what's available in your area.

2027 numbers worth knowing

Even if you're not switching plans, a few program-level figures for 2027 are useful to keep in mind:

• The Part D out-of-pocket cap is $2,400 in 2027 (up from $2,100 in 2026). Once your drug spending hits that ceiling, you pay nothing for covered drugs the rest of the year.
• The Part D maximum deductible is $700 in 2027 (up from $615 in 2026).
• The old "donut hole" coverage gap is gone. Part D now has three phases, not four.
• The Medicare Prescription Payment Plan lets you spread drug costs across the calendar year in monthly installments — worth asking about if a January refill hits hard.
• IRMAA surcharges (higher Part B and Part D premiums for higher incomes) begin above $109,000 for a single filer in 2026.
