Imagine learning during open enrollment that your Medicare Advantage plan is exiting the market, forcing you to find new coverage for 2026. In Vermont, a staggering 92% of Medicare Advantage enrollees face exactly this situation. Nationally, 2.9 million beneficiaries, roughly 1 in 10 Medicare Advantage enrollees, have been forced to change their insurance coverage due to their prior plan exiting the market (forced disenrollment). The research letter by Meiselbach and colleagues documents this unprecedented disruption. Between 2018 and 2024, mean forced disenrollment was just 1% annually. After years of stable market participation, forced disenrollment rates surged to 6.9% in 2025 and are expected to reach approximately 10% in 2026.
