Key takeaways

  • Medicare and employer benefits coordinate; they don't substitute.
  • Many plans reimburse Medicare-related premiums via 401(h) or HRA.
  • Pre-Medicare retirees often face the biggest coverage gap.
  • Plan communications must be clear or retirees will misstep.

Medicare in two minutes

Medicare provides a baseline of coverage for most U.S. retirees age 65+, with Parts A, B, D, and supplemental options. Premiums and out-of-pocket costs still apply.

Where employer benefits fit

Employer retiree benefits — including 401(h) reimbursements and HRA-based programs — often coordinate with Medicare by covering premiums, supplemental costs, and qualifying out-of-pocket expenses.

The pre-Medicare gap

Retirees who leave before 65 face a coverage cliff. Some employer programs target this window specifically. Others don't, and that needs to be clear up front.
