WASHINGTON—A Biden administration proposal to protect seniors from sudden doctor network disruptions in Medicare Advantage plans has been shelved indefinitely amid fierce lobbying from insurers and provider groups, according to three sources familiar with the matter. The delay leaves millions of enrollees vulnerable to mid-year care interruptions as hospitals and physicians increasingly exit the privatized Medicare programs.
The stalled regulations would have required insurers to maintain stable provider networks for at least 90 days after patients enroll and provide 60-day advance notice of significant network changes. Analysts say the retreat reflects mounting tension between insurers seeking to control costs and providers demanding higher reimbursement rates. “This was a rare consumer protection that got caught in the crossfire,” said a healthcare policy analyst at a nonpartisan think tank who requested anonymity to discuss sensitive negotiations.
Medicare Advantage now covers 33 million Americans—over half of all Medicare beneficiaries—through private plans that often offer lower premiums than traditional Medicare but restrict provider choice. Federal data shows network instability has worsened since 2023, with 12% of enrollees experiencing a primary care physician departure from their plan last year. Hospital systems like Mayo Clinic and Cedars-Sinai have exited some Advantage networks entirely, citing unsustainable payment models.
Insurers argue the proposed rules would have raised premiums by limiting their ability to negotiate with providers. “Arbitrary network freezes undermine market-based solutions,” said a spokesperson for America’s Health Insurance Plans. Consumer advocates counter that the status quo allows insurers to “bait-and-switch” seniors with attractive networks that quickly erode. The administration has not indicated when—or if—the protections might be revived.
Experts warn the impasse could accelerate as Medicare Advantage growth slows and providers gain leverage. “We’re entering a phase where hospitals would rather walk away than accept lowball rates,” noted a healthcare economist at Moody’s Analytics. With open enrollment approaching this fall, seniors may face tougher choices between affordability and reliable access to care.
