Medicare Open Enrollment for 2027

The Annual Medicare Open Enrollment Period (OEP) runs from October 15 through December 7.   

Any changes you make to your Medicare coverage during this time will become effective January 1, 2027.

  • Your Medicare card
  • All current insurance cards (including prescription drug and supplemental coverage)
  • A current printed list of your medications
  • A current list of your physicians and specialists

Once we receive your completed worksheet and all required documents, our office staff will schedule an appointment for you with an Outreach Specialist during the Open Enrollment period.


We encourage all Medicare beneficiaries to review their coverage each year, Medicare plans, premiums, deductibles, copayments, formularies, and provider networks can change annually.  Reviewing your options helps ensure you have the coverage that best meets your healthcare needs and budget for the coming year.
