The Medicare open enrollment period is almost over, but time remains to make changes in your Medicare plan for 2019.  This year brings the most significant changes in the enrollment process since the Medicare Part D drug benefit was introduced in 2006.  Minnesota is especially impacted because Cost Plans, a type of Medicare plan very popular in our state, will no longer be available in much of the state for 2019 due to a change in federal law. This means about 375,000 Minnesotans will need to change their Medicare coverage.


Most of the one million Minnesotans with Medicare are not affected by the Cost Plan change, and beneficiaries in 21 counties will be able to keep their Cost Plans in 2019 because of limited Medicare options where they live. But the majority of Cost Plan beneficiaries will have to choose new coverage for 2019 or risk returning to Original Medicare, which could be very costly. They were notified of this change by Medicare and their Cost Plan insurers earlier this fall.    Beneficiaries should review their Medicare options to make sure the plan they are considering for 2019 is both affordable and provides access to the doctors, clinics, hospitals and pharmacies they want and need.


The Minnesota Board on Aging’s Senior LinkAge Line can help. The free information and assistance service now and every year helps Minnesotans on Medicare weigh their plan options by providing them with free, comprehensive, unbiased Medicare counseling. This year, Senior LinkAge Line is extending its business hours and will be open from 8 a.m. to 6 p.m. Monday through Thursday and from 8 a.m. to 4:30 p.m. on Friday. You can contact specialists at 1-800-333-2433 and via chat at
