…have recently become or soon will be eligible for Medicare.

If you become eligible for Medicare through age or disability, you have a seven-month window for enrollment in Medicare Advantage and Part D plans: the month you become eligible, the three months prior, and the three months after. If you apply for a Medicare supplement, there is a six-month window from your eligibility date to enroll in a supplement without completing a health questionnaire. If you do not enroll within this time period (unless you have other non-Medicare coverage), you may have special limitations on when you can apply and you may incur cost penalties.

These dates may not apply if you are eligible due to a move, a Special Election Period (SEP) or other exceptions, such as leaving a group plan. Please call us at 1-888-734-3623 for more information. TTY users should call 1-800-382-1003 in Oregon and Idaho; in Washington and Utah call 1-800-833-6384.
