Roughly 600,000 people enrolled in Humana Medicare Advantage plans are set to lose that coverage in 2027, after the insurer said it will pull out of its least profitable markets. The move is a business decision aimed at repairing thin margins, but the fallout lands on members who will have to shop for a new plan during this fall’s enrollment season. For anyone in an affected plan, the calendar and the details of the switch matter more than the corporate strategy behind it.
Why Humana is cutting plans it calls unprofitable
Humana laid out the plan during its second-quarter earnings call, describing 2027 exits from markets where its Medicare Advantage business loses money. Rather than trimming benefits evenly everywhere, the company said it would “cut off the lower tail of profitability,” concentrating the cuts on the weakest plans while keeping the rest.
The stated goal is financial: Humana said its top priority is returning to a sustainable operating margin of at least 3%, a level it has struggled to hold as older members use more medical care than the company projected. According to the company’s earnings disclosure, the exits are part of an expected margin recovery in 2027, even as Humana reported its individual Medicare Advantage membership grew about 25% this year.

What “about 600,000 members” actually means for enrollees
An estimated 600,000 people are in the plans slated to disappear, but that is not the same as 600,000 people left with nothing. Humana said it will try to move some of that membership into its remaining plans, and industry reporting indicates the insurer expects to recapture roughly 40% of affected members, or on the order of 240,000 people, in other Humana offerings. The rest will need to choose coverage from another insurer.
A discontinued plan does not leave a member uninsured by surprise. When a Medicare Advantage plan exits, the enrollee receives a non-renewal notice and gains the right to pick a new plan or return to Original Medicare. The practical burden is the shopping itself: comparing premiums, provider networks, drug coverage and out-of-pocket caps to make sure a new plan still covers the same doctors and prescriptions.
The details are where people get tripped up. A replacement plan may carry the same monthly premium but drop a member’s cardiologist from its network, or move a regular prescription to a higher cost tier. Someone weighing a return to Original Medicare has a further wrinkle to consider: adding a Medigap supplement policy outside of a person’s initial enrollment window can require medical underwriting in many states, meaning an insurer can charge more or decline coverage based on health history. That makes the switch less about finding the cheapest premium and more about matching a plan to the doctors, drugs and supplemental coverage a member actually uses.
The fall enrollment window is where the choice gets made
The timing lines up with Medicare’s Annual Enrollment Period, which runs from October 15 to December 7 each year. That is the stretch when beneficiaries can join, switch or drop a Medicare Advantage or Part D plan, with coverage taking effect January 1. Anyone whose Humana plan is ending for 2027 will make the change during that window, and the official Medicare guidance on joining a plan spells out how to compare options and enroll.
Losing a plan involuntarily also carries an advantage worth using. Beneficiaries whose coverage is discontinued generally get a guaranteed-issue right to buy certain Medigap policies without health underwriting, a protection that does not apply to someone who simply changes their mind in an ordinary year. Acting during the enrollment season, rather than after it, is what preserves that option.
Members losing a plan also generally qualify for a Special Enrollment Period, giving extra time beyond the standard window to arrange replacement coverage. The key is not to let the notice sit: a plan that lapses without a chosen replacement can leave gaps in drug coverage or send a member back to Original Medicare without the supplemental protection they had counted on.
Plan turnover is becoming routine, and star ratings are part of it
Humana’s retreat is not an isolated event. Major insurers have been pruning Medicare Advantage plans for several years as costs climbed and federal payment and quality rules tightened. Quality scores, known as star ratings, feed directly into the bonus payments that make a plan profitable, and Humana has said it is pushing to lift its ratings toward the top quartile for the 2027 plan year after slipping on that measure.
For older readers, the lasting takeaway is that a Medicare Advantage plan is not a set-and-forget purchase. Plans can and do leave markets from one year to the next, which is why reviewing coverage each fall, rather than auto-renewing, is the habit that keeps a switch like this one from becoming a coverage gap. Humana said it will give investors and members a fuller update on its plan lineup and star ratings in December, close to the end of the enrollment window itself.
