Humana plans to discontinue Medicare Advantage plans covering roughly 600,000 members in 2027, a cut the insurer confirmed for investors on its July 29, 2026 earnings call. That figure represents about 9% of the company’s Advantage membership, and it marks one of the largest single-year contractions any major carrier has telegraphed heading into next year. Unlike a quiet county-by-county trim, this is a deliberate, company-wide pruning of plans Humana no longer considers viable. For the members swept up in it, a federal safety valve exists, but it comes with a firm deadline.
The 600,000-member reduction Humana disclosed to investors
Humana’s leadership framed the exit as a matter of profitability rather than retreat. Roughly 9% of its Advantage book sits in plans the insurer intends to drop, and management described the decision as shedding coverage that has been losing money under current federal payment levels. The company signaled that walking away from those plans, even at the cost of hundreds of thousands of members, would leave a healthier and more stable book behind.
The scale is what separates this from ordinary year-to-year adjustments. Six hundred thousand people is a population larger than several U.S. cities, and each of them will need to make an active coverage choice for 2027. Humana disclosed the number on its second-quarter earnings call, positioning the move as central to its strategy of prioritizing margins over raw enrollment growth.
The move also fits a broader industry pattern. Rival carriers have signaled their own 2027 pullbacks as federal payment updates tighten and medical costs climb, and Humana’s decision sits at the larger end of that trend rather than standing alone. What distinguishes it is transparency and scale: the company put a firm membership figure in front of investors instead of letting the reductions surface quietly, county by county, in the fall filings.
For an affected member, the disclosure carries a blunt consequence. When a specific plan is terminated, continuation is not an option, and the enrollee must either move to another Humana plan, switch carriers, or return to Original Medicare with supplemental coverage.

The guaranteed-issue Medigap right the dropped members gain
The exit does trigger a protection that ordinary shoppers do not always have. When an Advantage plan is discontinued and a member is forced out, federal rules generally grant a guaranteed-issue right to buy certain Medigap supplement policies without answering health questions. That matters because outside of these special situations, a Medigap insurer can normally reject an applicant or charge more based on medical history.
Guaranteed issue means an insurer must sell the eligible enrollee one of the qualifying supplement plans, cannot use health status to deny the application, and cannot impose a higher premium tied to preexisting conditions. Someone leaving a terminated Humana plan for Original Medicare would typically hold a guaranteed-issue right to buy a Medigap policy within a limited window around the plan’s end date. Missing that window can forfeit the protection and reopen the door to underwriting.
The right is narrower than a first-time buyer’s open enrollment. It applies to specified plan letters, runs on a tight clock, and does not cover every supplement on the market. Still, for a member with health conditions who wants to leave Advantage, it can be the difference between securing a supplement and being turned away.
The catch is that the protection is time-boxed and easy to forfeit. The special guaranteed-issue window opens around the plan’s termination and lasts only a limited stretch, so a member who waits until January to sort out coverage may discover the door has already closed. Adding a standalone Part D drug plan is a separate step for anyone returning to Original Medicare, since a supplement does not include prescription coverage on its own.
How the December 7 deadline shapes the decision
The calendar governs everything. Medicare’s annual open enrollment closes on December 7, and that is the window in which a displaced Humana member can pick a 2027 plan that takes effect January 1. A senior who allows the date to pass without choosing a replacement risks a gap in coverage or a fallback that may not fit their doctors and medications.
Two forces pull in different directions during those weeks. The guaranteed-issue Medigap right rewards members who move quickly toward Original Medicare plus a supplement, while the convenience of staying within the Advantage world may push others toward a different Humana or competitor plan. Comparing both routes during Medicare’s fall open enrollment is the only way to weigh premiums, drug coverage, and network access against the protection a supplement offers.
Marketing pressure complicates the choice further. When a plan is discontinued, the insurer typically steers displaced members toward its own remaining Advantage products, and competing carriers court them heavily during the same weeks. That crossfire can nudge a senior into whichever plan is advertised most aggressively rather than the one that best fits their doctors, medications, and budget. The guaranteed-issue supplement route is rarely the option marketed hardest, even when it is the more protective long-term fit.
What remains genuinely unsettled is how many of the 600,000 will land softly. The guaranteed-issue right cushions those who understand it and act inside the deadline, but it does nothing for a member who assumes their plan will simply roll over. That gap between the protection on paper and the seniors who actually use it is the real story behind Humana’s 2027 retreat.
