About 600,000 Humana Medicare Advantage members are due to receive notices this fall that their current plan will not exist in 2027, and federal timing rules mean those letters have to land in early October, just before the annual enrollment window opens on the fifteenth. The company disclosed the scope of the pullback on its second-quarter earnings call in July, but the mechanics of when members actually find out are set by a federal notice requirement, not by Humana’s own preference. For an enrollee whose plan turns out to be one of the ones exiting, the calendar leaves only a narrow stretch of days between finding out and needing to act.
Why the Notices Have to Land Before Enrollment Opens
Federal regulation spells out exactly how much warning a Medicare Advantage member is owed when an insurer walks away from a contract. Under 42 CFR 422.506, an insurer that will not renew a contract must notify each enrollee by mail “at least 90 calendar days before the date on which the nonrenewal is effective,” and for the calendar-year contracts most Medicare Advantage plans run on, that notice must specifically be dated by October 2 to keep Medigap guaranteed-issue rights consistent nationwide. That federal arithmetic is what pushes Humana’s letters into early October, arriving just before Medicare’s annual Open Enrollment period, which runs October 15 through December 7 and is when affected members can pick a replacement plan.

Humana’s Own Numbers Behind the Exit
Humana’s chief financial officer, Celeste Mellet, disclosed the scope of the 2027 exits on the company’s July 29 second-quarter earnings call, telling investors the pullback would affect around 600,000 members, or roughly 8% of the insurer’s 7.2 million Medicare Advantage enrollees. Mellet said the company would “work to recapture a significant portion of that volume as we did in 2025,” when Humana kept just over 40% of members whose plans were discontinued by steering them into other Humana plans. Rather than trimming benefits evenly across its book of business, Humana is targeting what Mellet described as the lower tail of profitability, with the majority of exiting plans rated 3.5 stars or lower for the 2027 bonus year, even as the company maintains that star ratings were not the primary driver of which plans it cut. The company has said separately that about 20% of its members are in plans rated 4 stars or higher for 2026, a reminder that the 2027 cuts are concentrated in a specific slice of Humana’s overall Medicare Advantage book rather than spread evenly across every market it serves.
A Pullback That Runs Against the Rest of Humana’s Growth
The 2027 exits arrive in the middle of otherwise strong growth for the company, which added more than 1 million Medicare Advantage members for 2026 coverage and expects roughly 25% individual membership growth this year, even as larger rivals moved the opposite direction: UnitedHealthcare’s Medicare Advantage membership fell about 9% and Elevance Health’s fell 14% during the last annual enrollment period. Humana posted $40.9 billion in second-quarter revenue, up 26% year over year, and adjusted earnings per share of $7.61 that beat analyst expectations, though the company lowered its full-year GAAP earnings guidance as lower star ratings cut into the quality bonus payments CMS ties to plan performance.
Two Straight Years of Retrenchment Behind the 2027 Cuts
The coming exits follow, rather than break, a pattern. Humana shed roughly 500,000 members in 2025 while exiting unprofitable plans and counties, and its 2026 footprint narrowed to 46 states and 85% of U.S. counties, down from 89% the year before. The squeeze playing out across the industry is also visible in federal rate-setting: CMS finalized only a 2.48% average Medicare Advantage rate increase for 2027 in April, well below what more than 100 organizations had urged the agency to adopt, citing exactly the kind of plan exits and enrollee instability now landing in Humana members’ mailboxes.
A member losing a plan mid-relationship is often the same person who discovers only then how many separate assistance programs touch a Medicare bill. Someone forced to shop for new coverage this fall is also a good candidate for a Medicare Savings Program or the Extra Help drug-cost subsidy, two programs that can lower a Part B premium and prescription costs but are never offered automatically alongside a new plan selection, so a household has to know to ask. Both programs go unclaimed by large numbers of people who would qualify, simply because the income limits and application offices differ from state to state. The Benefits Checklist lays out the 2026 income limits for Medicare Savings Programs and Extra Help alongside the state office that handles each application, built for exactly the moment an enrollee is already re-shopping coverage.
