Retirees Face Medicare Open Enrollment: Oct 15-Dec 7 Deadline

Image from the source feed · MarketWatch

Open enrollment for Medicare runs Oct 15-Dec 7, giving seniors a window to change plans, add coverage, or adjust premiums before the next year.

Medicare beneficiaries have a limited window each year to adjust their health coverage. The upcoming open‑enrollment season starts on October 15 and ends on December 7.

During this period, seniors can switch between Medicare Advantage plans, enroll in or drop supplemental insurance, and modify prescription drug coverage without penalty.

Missing the December 7 deadline means any changes will take effect only in the following year, so careful review of current plans is advised.
