If I have both Medicare and employer health insurance, which one pays first?

Question

Brandi Griffin · Accepted Answer

The answer depends mainly on the size of your employer and your specific situation.

If you work for an employer with 20 or more employees: Your employer's group health plan typically pays first, and Medicare pays second.

If you work for an employer with fewer than 20 employees: Medicare is generally the primary payer, and your employer's plan pays second.

If you're covered under a spouse's employer plan: The same general rules often apply based on the size of your spouse's employer.

If you have retiree health coverage: Medicare usually pays first, and the retiree plan pays second.

Because every situation is unique, factors such as disability, COBRA coverage, or End-Stage Renal Disease (ESRD) can change which plan pays first.

Ann Sanfelippo · Answer

f you have both Medicare and employer health insurance, which plan pays first depends primarily on the size of your employer. If your employer has 20 or more employees, your employer health plan generally pays first, and Medicare pays second. If your employer has fewer than 20 employees, Medicare usually pays first, and your employer plan pays second.

Because coordination of benefits can vary based on your specific situation, it's important to review your coverage before delaying Medicare enrollment or relying solely on employer insurance.

The primary payer depends on company size:

• 20 or more employees: Your employer plan pays first, and Medicare pays second.

• Fewer than 20 employees: Medicare pays first, and your employer plan pays second

Kristina Guerry · Answer

If you have Medicare and employer coverage insurance, typically your employer coverage will pay first if there are 20 or more employees. If there are less than 20, Medicare would pay first. You can locate this information on Medicare.gov and look up, "Coordination of Benefits".

Depends on the number of employees, over 20 then employer is primary, under 20 then Medicare is primary.  There are other factors that may apply but this is a main one.

Michael Craig · Answer

It depends. Madicare pays first if the employer has 20 or more employees. With smaller plans the employer pays first. Any other questions check with an agent in your area on this site.

Rosie Lawless · Answer

Medicare will pay first, and your employer health insurance (or your spouse's) health plan will pay second. If there is more than 20 plus employees, then the employer health plan will pay first and Medicare as a backup. Just depends on the situation.

The easy answer Is medicare will pay first but never assume which insurance pays first. Coordinating your benefits correctly can help you avoid unexpected medical bills and gaps in coverage. I can help you determine the correct order based on your employment status and your employer’s size.
