Medicare secondary payer

Medicare was always primary ?. How do you determine primary or secondary?

In most cases, Medicare is primary. Some of the most common situations where Medicare can pay secondary are:

-The individual or his/her spouse is currently employed/working and covered under an employer group health plan as a result of current employment.The company has 20 or more employees or participates in a multiple

 -employer or multi-employer group health plan where at least one employer has 20 or more employees.

  

-Individual in question is entitled to Medicare as a result of a disability, the company has 100 or more employees, or participates in a multi-employer/multiple-employer group health plan where one employer has 100 or more employees.

  

-The individual in question is Medicare entitled due to end-stage renal disease. Medicare is the secondary payer to a group health plan until a 30-month coordination period has ended.
