Every fall, a stack of Medicare mail lands in your mailbox. Most years you can skim it and move on. This year is different for some people, because Medicare Advantage changes in 2027 will end certain plans outright. Let’s walk through what those letters actually mean and which doors they open.
What’s Driving Medicare Advantage Changes in 2027
The story starts with one large carrier. In late July 2026, Humana told investors it plans to exit Medicare Advantage plans covering roughly 600,000 members. That is about 8% of its 7.2 million Medicare Advantage enrollees. Healthcare Dive covered the announcement, which came straight from the company’s second-quarter earnings call.
Humana’s CFO, Celeste Mellet, framed it as a math problem, not a service problem. The company wants to return to a sustainable margin of at least 3% by 2028. Humana also expects to move about 40% of affected members into its remaining plans. In other words, many people will get a replacement offer from the same carrier.
Ritter Insurance Marketing adds two details worth knowing. Most of the affected plans carry star ratings of 3.5 or lower. And Humana has not yet published which counties or which specific plans are on the list. That second point matters. You cannot simply look yourself up today, however much you’d like to.
Zoom out and the national trend is real. KFF counted 3,373 Medicare Advantage plans available for 2026, a 9% decline from 2025. The average beneficiary had 32 plans with drug coverage to choose from, down from 34. Utah, however, was one of only six states where the average beneficiary gained options rather than lost them. So the national contraction is genuine, and Utah has been an exception so far. That is a good reason to read your own letter carefully instead of assuming.
ANOC or Non-Renewal? Two Very Different Letters
For most people, Medicare Advantage changes in 2027 will show up as one of two envelopes. They look similar. They mean very different things.
The Annual Notice of Change
Your plan mails the Annual Notice of Change, or ANOC, so it reaches you by September 30. It lists what changes on January 1. Think premiums, copays, the drug formulary, and the provider network.
An ANOC means your plan still exists. You are not required to do anything. Reading it is still a good idea, because a plan can change a lot and keep the same name.
The Non-Renewal Notice
This letter says something stronger. Your plan is leaving Medicare, or it is no longer serving your county, as of December 31. These notices typically go out in early October, and Medicare mails its own reminder notice in November.
If you receive this one, you do need to act. The good news is that you get more room to act than most people realize. If telling the two letters apart feels like homework, that is exactly the sort of thing our Medicare team helps Utah families sort out every fall.
The Guaranteed Issue Right Almost Nobody Mentions
Here is the most valuable thing Medicare Advantage changes in 2027 can hand you. When a Medicare Advantage plan leaves Medicare or stops covering your area, you gain what Medicare calls a guaranteed issue right. Medicare.gov spells this out directly. You can buy Medigap Plan A, B, C, D, F, G, K, or L from any company selling it in your state.
Guaranteed issue is a short phrase with a big meaning. The insurance company must sell you the policy. No health questions. No underwriting. No waiting period for a condition you already have.
That protection is unusual. Outside of a window like this one, Medigap carriers in most states can decline you or charge you more based on your health history. A non-renewal notice hands you a rare open door.
The door does not stay open forever. Your window starts 60 days before your coverage ends and closes 63 days after it ends. Put both dates on the calendar the day your letter arrives. There is one more wrinkle worth knowing. If you held a Medigap policy before joining Advantage, you may be able to buy that same policy back, provided the company still sells it.
Whether Medigap is the right move depends on your doctors, your budget, and how you like to pay for care. Our Medicare Supplement plan page explains how those policies work alongside Original Medicare. Plenty of people prefer the Advantage structure and simply want a replacement, which is a perfectly good answer too. In that case, start with our guide to shopping for a Medicare Advantage plan. Still fuzzy on how the two paths differ? Our post on Medicare basics, Parts A and B, and choosing your coverage covers the fundamentals in plain language.
Your Calendar for Medicare Advantage Changes in 2027
Two enrollment windows matter here, and the second one surprises people. Open Enrollment runs October 15 through December 7, with changes taking effect January 1. During that stretch you can join, drop, or switch Advantage plans. You can add or drop drug coverage. You can also move between Original Medicare and Medicare Advantage in either direction.
December 7 is not the end of the road, though. When a plan’s contract is not renewed, affected members get a Special Enrollment Period that runs December 8 through the last day of February. So a December letter does not leave you stranded.
One caution about that safety net. The Special Enrollment Period lets you pick a new plan. It does not carry the Medigap guarantee with it. That guarantee runs on its own 63-day clock, and the two do not always line up.
What Happens If You Do Nothing
You will not lose coverage. Medicare enrolls you in Original Medicare if your plan ends and you do not choose another one. Your Part A and Part B benefits continue as normal.
Two gaps open up, though. Original Medicare has no annual cap on what you spend out of pocket. It also includes no prescription drug coverage at all. Going without Part D for too long can trigger a late enrollment penalty, and that penalty sticks to your premium for as long as you have coverage. A quick look at our Medicare prescription drug plan options is a cheap way to avoid an expensive surprise.
While You’re Reviewing Anyway: 2027 Costs
Since you’ll have the paperwork out, it helps to know where costs are heading. Drawing on the Social Security and Medicare Trustees Report, Kiplinger projects a 2027 Part B premium of $209.50 per month with a $292 deductible. Treat both as projections rather than final figures. CMS confirms the real Part B numbers in November.
The Part D side is further along. The 2027 base premium is set at $41.33, and the out-of-pocket cap lands at $2,400. Those figures are finalized, so you can plan around them with more confidence.
The Takeaway
Medicare Advantage changes in 2027 will not touch everyone, and Utah has held up better than most states. But if a non-renewal letter does arrive, treat it as a deadline with options attached rather than bad news. It hands you an extra enrollment window and, for many people, a one-time chance at a Medigap policy with no health questions asked. The only real mistake is leaving the envelope unopened.
