Medicare Advantage Forced Disenrollment: 2027 Agent Guide

About 1 in 10 Medicare Advantage members are being pushed out of their plan in 2026, whether they wanted to leave or not, according to a peer-reviewed research letter published in JAMA in February 2026. That’s roughly 2.9 million people whose plan exited their county, non-renewed its CMS contract, or got terminated outright, up from a rate that sat near 1% a year for most of the last decade. Humana has already told investors it expects a similar wave for 2027, affecting around 600,000 of its own members. None of those people asked to shop for new coverage. They’re getting a letter that makes the decision for them, on a clock the federal government sets.

That’s the pain point this article opens on: you have clients whose plan is about to disappear out from under them, a small window to reach them before a call center or a competing agent does, and a compliance framework around Medicare marketing that doesn’t relax just because the client already knows your name. Everything below covers what’s actually driving the surge, the exact notice and enrollment timelines CMS enforces, what it costs an agency that works this list slowly, and how to work it fast without cutting a compliance corner. Where a managed AI caller fits into that, and where it doesn’t, comes at the end, pointed at a demo and pricing, not before.

What Forced Disenrollment Actually Means

“Forced disenrollment” isn’t a term CMS uses in its own regulations, but it’s the accurate name for what happens across three distinct legal events, and the difference between them changes the calendar every client is on. Define them once, because the rest of the article depends on keeping them straight.

Non-renewal. A Medicare Advantage organization decides, on its own schedule, not to renew its annual contract with CMS for a specific plan or in a specific county for the next plan year. This is the most common route and the one behind most of the 2026 and 2027 volume. It’s governed by 42 CFR 422.506.

Termination. CMS itself ends a plan’s contract, usually for a compliance failure, mid-cycle rather than at year’s end. This is rarer and carries its own, different enrollee notification and Special Enrollment Period rules than a routine non-renewal.

Service area reduction (SAR). A plan keeps operating but stops covering one or more counties it used to serve, effectively non-renewing for the members in the dropped counties while continuing to sell the same plan everywhere else. From the affected member’s seat, this looks and functions exactly like a full non-renewal.

Every one of these events produces the same downstream fact for an agent: a member who did nothing wrong and made no decision now has a deadline to pick new coverage, and they’re going to make that decision with or without you. Whoever calls first, explains the options clearly, and helps them act inside the window usually keeps the relationship. Whoever doesn’t usually finds out later that the client auto-enrolled into whatever CMS’s default crosswalk assigned them, or called the number printed on the notice and ended up with a call-center agent instead.

The Numbers Behind the 2027 Surge

Researchers at Johns Hopkins Bloomberg School of Public Health, in a research letter published online in JAMA on February 18, 2026, linked CMS county-level Medicare Advantage enrollment data from 2017 through 2025 with the plan crosswalk files that capture terminations and the landscape files that document service areas, covering 752,091 plan-county observations and 192.7 million enrollee-years. Their finding: the forced disenrollment rate, which had averaged close to 1% a year from 2018 through 2024, jumped to 6.9% in 2025 and reached about 10% overall in 2026, or 12.4% among non-SNP plans specifically. In raw numbers, that’s roughly 2.9 million Medicare Advantage members losing their plan through no choice of their own in a single year.

The distribution isn’t even. Vermont recorded the most extreme state-level rate in the JAMA data, 92.2% of its Medicare Advantage enrollees facing forced disenrollment, and the researchers counted 12 states overall where more than 20% of enrollees were affected. Rural counties with thin insurer competition tend to sit at the high end, because a single carrier’s exit can wipe out most or all of the local Medicare Advantage market at once, leaving Original Medicare as the only remaining option for anyone who doesn’t want to switch to a different plan sight-unseen.

For 2027, the clearest early number comes not from a research letter but from a carrier’s own mouth. On Humana’s Q2 2026 earnings call, held July 29, 2026, CFO Celeste Mellet told analysts the company’s 2027 plan exits would affect “approximately 600,000 members,” concentrated in plans rated 3.5 stars or lower for the 2027 bonus year, and that Humana expects to recapture “just over 40%” of them into its other plans, matching its 2025 recapture rate. That’s a single insurer’s own projection, not a verified industry total, and it’s worth treating it that way in front of clients: real, sourced, and specific to one company’s book, not a universal number for every carrier or every county.

That tension is worth naming out loud with a client rather than glossing over. CMS’s own September 2025 release projected 2026 would look stable at the market level. The people actually losing their plan don’t experience a stable market. They experience one letter, with their name on it, telling them their coverage ends soon.

The Clock: Notice Dates and Enrollment Windows

Here’s the mechanism that actually creates the speed-to-lead problem: three different federal timelines, all triggered by the same underlying event, and a member who has no reason to know which one applies to them.

Under 42 CFR 422.506(a)(2), a Medicare Advantage organization that decides not to renew its CMS contract has to notify CMS in writing by the first Monday in June of the year the contract would end, and has to mail a written notice to every affected enrollee at least 90 calendar days before the nonrenewal takes effect. For the overwhelming majority of MA contracts, which run on a calendar year and end December 31, that 90-day math lands the mailed notice around October 1 or 2. The Center for Medicare Advocacy describes this as the standard timing plans use specifically so that Medigap guaranteed-issue rights apply consistently across the country, regardless of which carrier or state a member happens to be in.

Once that notice goes out, the enrollment clock that actually matters to the member starts. Medicare.gov’s own rules on Special Enrollment Periods lay out three separate windows depending on why the plan is ending, and they are not interchangeable:

Layered on top of the enrollment window is a separate, shorter clock for Medigap. According to the Center for Medicare Advocacy, an enrollee whose plan terminates its Medicare contract, exits their service area, or is found to have violated its contract gets a guaranteed-issue right to buy Medigap Plan A, B, C, F, K, or L without medical underwriting, but only if they apply within 63 days of the old coverage ending. That window is materially shorter than the enrollment SEP, and it’s the one clients are least likely to know exists on their own, which is exactly where a licensed agent’s explanation earns its keep.

What Waiting Costs

Run the actual math on a book of a few hundred affected clients, because “call them eventually” and “call them this week” produce very different outcomes here. Say your agency has 400 clients sitting on a plan that just got a non-renewal notice. The SEP is fixed at roughly 12 weeks, December 8 through the end of February. Every one of those 400 people is also getting outreach from the plan’s own retention team, from competing agents who bought the same aggregated non-renewal list, and from whatever call-center number is printed on the notice itself. The underlying mechanism is the same one covered in our guide to speed to lead: whoever calls first tends to keep the relationship, and a forced-switch list compresses that race into a fixed calendar window instead of the usual few hours.

Price the fix against that same 400-client list. Using TheAffordableAI’s published Single Account rate of $0.20 a minute, a 5-minute plan-change explanation call runs $1.00, or $400 to call the full list once. At the Agency plan’s bulk rate of $0.16 a minute, the same 400 calls run about $320. Both plans are month to month with no long-term contract, which matters here specifically because a non-renewal list is a seasonal spike, not a standing monthly volume, and neither plan locks you into paying for capacity you only need for twelve weeks a year.

How to Work the List

None of this requires new software to start. You can do the first four steps with a spreadsheet and the notices your carrier relationships already surface.

1. Identify which of your carriers have filed 2027 non-renewals or service area reductions in your counties. Watch for the first-Monday-in-June CMS notification date and carrier earnings calls, like Humana’s, that flag exits ahead of the formal landscape files. If this list lands on top of your normal AEP call surge, plan the staffing for both at once rather than queuing one behind the other.
2. Cross-reference your own book against the affected plans and counties the moment you know them, rather than waiting for CMS’s landscape files in September. A carrier’s own investor disclosures are a real, sourced early signal, even before the specific counties are public.
3. Flag every client on an affected plan with the date their notice will legally have to mail, roughly 90 days before their plan’s contract end date, so you’re calling ahead of the letter landing in their mailbox, not after.
4. Separate the guaranteed-issue Medigap candidates from the rest of the list. Anyone planning to drop Medicare Advantage entirely and go to Original Medicare plus a Medigap policy is working against the shorter 63-day clock, not the full SEP window, and needs to hear that distinction explicitly.
5. Call before the SEP opens if you already know the plan is exiting, using the notice period itself to educate and schedule, then confirm and complete the actual plan change once the December 8 window opens.
6. Document the call basis and consent for every contact, especially for clients reached by automated or AI-voice calls, since a prior relationship helps the compliance picture but doesn’t erase the underlying TCPA consent requirement.
7. Track who called the number on the letter before you got to them. That’s not a failure to fix retroactively; it’s a data point for narrowing next year’s list to the clients who actually wait for their own agent.

What You Get

The Compliance Part, Said Plainly

A forced plan exit doesn’t relax anything about how you’re allowed to contact a client.

Where This Isn’t the Right Tool

An AI caller is built for volume against a list you already have and a message you already know how to deliver. It’s not a substitute for the actual coverage conversation a client whose Medicare Advantage plan just disappeared needs to have with a licensed human being about their specific health needs, prescriptions, and provider network. If your affected book is a few dozen clients, call them yourself; a small, high-stakes list like that rewards a personal conversation more than automation.

It also can’t tell you which of your carriers are actually exiting which counties for 2027. That’s a research and relationship problem, tracking earnings calls, carrier notices, and eventually CMS’s own landscape files, that a faster caller doesn’t solve by itself. Build the list first. Decide whether speed is still the bottleneck once you actually know who’s affected.

The 2.9 million people who lost their Medicare Advantage plan in 2026, and the roughly 600,000 more Humana alone expects to affect in 2027, aren’t shopping because they want to. They’re shopping because a letter told them their coverage is ending on a date they didn’t pick. The agent who reaches them first, explains the 90-day notice, the SEP window, and the 63-day Medigap clock clearly, and helps them act inside it, keeps the relationship. The one who waits for AEP volume to slow down finds out later that the client already called the number printed on the letter.
