Clear Spring Health has left the Medicare Advantage business for good, closing out its remaining plans in Illinois, Georgia and Colorado. The exit, which took effect on June 1, 2026, forced more than 12,000 members to find new coverage in the middle of the year rather than during the usual fall enrollment season. It is one more example of a broader retreat from Medicare Advantage — and a reminder that when a plan disappears, the people enrolled in it face a decision with real cost attached.
Clear Spring Health’s full exit from Medicare Advantage
The Park Ridge, Illinois-based insurer exited the Medicare Advantage market entirely effective June 1, 2026, discontinuing its remaining business across all three states where it still operated. Clear Spring Health had more than 12,000 Medicare Advantage members as of April 2026, and the shutdown was not its first pullback: the company had already exited South Carolina and Virginia at the start of 2025. Founded in 2017, it wound the business down after less than a decade in the market.
The move fits a pattern that has accelerated across 2026 and into 2027, as insurers of varying sizes step back from Medicare Advantage under cost and profitability pressure. Clear Spring’s departure is one of several documented in industry reporting on insurers retreating from the market, and its members were left to move to another Medicare Advantage plan or return to Original Medicare.

What a mid-year exit means for the 12,000 affected members
A plan leaving on June 1 is unusual in its timing, and that timing matters. Most coverage changes happen at year-end, when members expect to review options. A mid-year departure lands when enrollees are not looking, which raises the risk that someone assumes their coverage is intact until a claim is denied or a bill arrives. Every affected member had to actively choose a replacement rather than let a plan renew.
The cost consequences run through the same channels as any plan change. A new Medicare Advantage plan can carry different premiums, deductibles and out-of-pocket limits, and — often the bigger issue — a different network of doctors and hospitals. A member whose physician is not in the replacement plan faces either higher costs or a switch in care. Drug coverage can change as well, altering which medications are covered and at what price.
Clear Spring’s history hints at how these exits tend to unfold. The company left South Carolina and Virginia at the start of 2025 before withdrawing from its final three states in 2026, a staged retreat that gave earlier members warning while leaving the last cohort to exit all at once. For a plan founded in 2017, the full wind-down after less than a decade also signals how quickly a Medicare Advantage insurer can decide the business no longer works — and how little a member’s tenure with a plan guarantees its continuation.
The Special Enrollment Period a plan’s departure triggers
Members of a plan that exits do not have to wait for the fall to act. A plan’s departure triggers a Special Enrollment Period, a window created specifically so that people losing coverage can join another Medicare Advantage plan or return to Original Medicare without penalty. For Clear Spring’s members, that window was the mechanism that let them line up new coverage after the June 1 shutdown.
Outside of a triggered special window, the standard time to change plans is Medicare’s Annual Enrollment Period, which runs from October 15 to December 7 each year, with new coverage effective January 1. Medicare’s guidance on joining a plan lays out how these windows work and how to enroll. Anyone whose plan announces an exit should confirm the deadline that applies to their situation rather than assume the fall enrollment period is their only option.
Timing also governs the exposure in between. Because a discontinued plan keeps its network rules in force until coverage actually changes, a member who seeks non-emergency care outside the plan’s network before enrolling in a replacement can be left owing the difference. Lining up new coverage promptly, and keeping care in network until it takes effect, is what closes that gap — a detail that matters most in a mid-year exit like Clear Spring’s, when members may not be watching their coverage as closely as they would in the fall.
Weighing Original Medicare against another Advantage plan
A plan exit reopens a choice many members made years earlier: stay in Medicare Advantage with a new carrier, or return to Original Medicare. Each path carries trade-offs around networks, out-of-pocket costs and supplemental coverage, and the right answer depends on a person’s doctors, prescriptions and budget. The one option that tends not to serve anyone well is inertia — letting a coverage gap open because the paperwork went unread.
The practical takeaway from the Clear Spring case is that plan exits are no longer rare events limited to the smallest insurers. With carriers of different sizes stepping back, more older Americans will receive a notice that their plan is ending. The households that read the notice, note which enrollment window applies, and compare replacements on total cost and network are the ones least likely to end up paying more or losing access to a trusted doctor.
