Over 87,000 Iowans Face Medicare Plan Cancellations as 2027 Open Enrollment Begins

October 15, 2026

by Press Release

The Medicare Open Enrollment Period (OEP) for 2027 Medicare Advantage and Part D Prescription Plans opens today, October 15, 2026, and runs through December 7, 2026. Ahead of this year’s enrollment window, more than 87,000 Iowa Medicare beneficiaries received notice that their current Medicare plan is being canceled or discontinued in their county.

A complete list of affected Medicare Advantage, Cost, and Part D plans, along with affected counties, is available on the SHIIP-SMP website at: shiip.iowa.gov/find-resources/whats-new-medicare.

"It’s more important than ever that Iowa Medicare recipients open and read mail from their Medicare plan to understand changes to their coverage and explore their 2027 options," said Kristin Griffith, Iowa’s SHIIP-SMP Director. "SHIIP-SMP is stepping up to empower Iowans with the knowledge, confidence, and support they need to find coverage that best serves them at the lowest possible cost."

Critical Coverage Changes

Loss of Mayo Clinic Network Guaranteed Issue Rights

A major change for 2027 is that Iowans will no longer be able to purchase Medicare Advantage plans that provide in-network coverage with the Mayo Clinic with the cancellation of both Wellmark and Medica’s Medicare Advantage PPOs.

Guaranteed Issue Rights

Iowans whose Medicare Advantage plans are canceled qualify for a "Guaranteed Issue" right. This allows them to switch to Original Medicare and purchase an available Medicare Supplement (Medigap) policy without medical underwriting—meaning insurers cannot deny coverage or charge higher premiums due to pre-existing health conditions.

"Having the ability to switch from Medicare Advantage to Original Medicare with guaranteed issue is a rare opportunity that isn't typically available to Medicare Advantage enrollees," Griffith noted. "It is vital for Iowans to weigh all their options given these significant changes."

Key Deadlines to Avoid Coverage Gaps

December 7, 2026: Standard Open Enrollment deadline for comparing and selecting 2027 Medicare Advantage and Part D plans.

December 31, 2026: Deadline for individuals losing their plan to select new coverage without experiencing a gap in coverage starting January 1, 2027.

February 28, 2027: Deadline to make changes under a Special Enrollment Period for those whose plans were canceled.

Medicare beneficiaries who fail to enroll in a new plan by December 31, 2026, risk coverage gaps on January 1, 2027, which could lead to substantial unexpected medical and prescription expenses.
