Medicare’s annual enrollment window runs October 15–December 7
CMS identifies October 15–December 7 as Medicare’s annual opportunity to review and change health and drug plans.
What the record says
CMS identifies October 15 through December 7 as Medicare’s annual open-enrollment period.
CMS advises beneficiaries to review plan information, including the Evidence of Coverage and Annual Notice of Change, because costs, coverage and participating providers can change.
Practical next step
Review the notices from your current plan and compare the plans relevant to your medicines and care. Use Medicare.gov or Medicare’s official help channels rather than assuming last year’s plan details still apply.
Limits and what is not established
Annual plan-change enrollment is not the same as initial eligibility enrollment. This report does not choose a plan, establish individual eligibility or guarantee that a particular clinician or medicine will be covered.
