When it comes to Medicare, timing is everything. Outside of the usual enrollment windows, there are Special Enrollment Periods (SEPs) that allow beneficiaries to make changes to their Medicare Advantage or Part D drug plans. One such SEP—SEP #6—applies when you join or drop employer or union health and/or drug coverage, whether current or former (retiree plan), regardless of whether the coverage is considered creditable.
Key Details of SEP #6
Who Qualifies?
- Individuals who choose to enroll in or disenroll from employer/union-sponsored Medicare Advantage or Part D plans.
- Those who decide to drop employer/union health or drug coverage, including COBRA.
- Retirees with former employer coverage making changes to their health benefits.
How Long Does the SEP Last?
- The SEP begins when your employer/union coverage ends.
- It continues for two months after the month your employer or union coverage ends.
When Does New Coverage Begin?
- Coverage can start as soon as the first day of the month following your plan application submission.
- In cases where the employer or union was late in processing your application, coverage might be retroactively effective to when you submitted your enrollment request.
Examples Relevant to Las Vegas and Henderson, Nevada
- Current Employee Transition: Maria, a Las Vegas resident, is 68 and works for a company that offers group health insurance. She decides to retire in June, ending her employer coverage. Maria has until the end of August to enroll in a Medicare Advantage plan or a Part D drug plan without penalty.
- Dropping Retiree Coverage: John from Henderson has retiree health coverage through his former employer. He finds a Medicare Advantage plan with better benefits and lower costs. John decides to drop his retiree coverage in March and enrolls in the new plan in April. His new Medicare Advantage plan starts May 1.
- COBRA Transition: After leaving her job, Linda from Summerlin enrolls in COBRA coverage. When she decides COBRA is too expensive, she opts to disenroll in February. Linda’s SEP lasts until the end of April, allowing her to enroll in a Part D drug plan without facing late enrollment penalties.
Important Considerations
- Creditable Coverage: Unlike other SEPs, SEP #6 applies whether your employer/union coverage is creditable or not.
- Avoiding Penalties: Enrolling promptly during the SEP helps avoid late enrollment penalties, especially for Part D drug coverage.
- Documentation: Always retain proof of when your employer or union coverage ended, as Medicare may require verification.
