Medicare open enrollment for 2027 is scheduled to start in October 2026. This enrollment period will include a sum of $90 for Part B beneficiaries, although most will not qualify. Changes are anticipated in Medicare Advantage plans, with 34 health systems dropping contracts. The Part D deductible will climb to $700 in 2027. Enrollment counselors in Iowa are getting ready for greater requests as a significant number of recipients face withdrawal from plans.
