Who Pays First
« on: January 10, 2019, 12:09:09 PM »
Does anyone have a chart or an easy way of remembering who pays first?  I don't know why I find this so confusing for me.  For example:  Medicare vs BCBS or Aetna, etc.

I'm hoping there is a chart I can reference until I can get it memorized and understood.

TIA for any assistance you can give.  : )

More than 90% of the time COB has already been established. The main problem is that many billers don't understand their are actually three different methods of COB a secondary can use to make payments.
If you contact the primary and secondary using good eligibility and benefits procedures you'll find the primary was already established. PMRNC also has a COB manual to help determine how payments and adjustments are posted using the three COB methods. You can find it in our store front at
