Question

What form should be attached to a CMS-1500 form submitted to a secondary insurance company?
A. a copy of the CMS-1500 sent to the primary insurance company.
B. An Explanation of Benefits (EOB)
C. a copy of the patient's medical treatment record.
D. a copy of the patient's ledger card

my answer is A. please help!

Answer 1

I think A is correct. The secondary insurance will need to see what the original charges were AND what was paid to the primary insurance co.

Answer 2

actually i think that it is B. Look around pg 118 bc if you send just the CMS-1500 the insurance company wont be aware of the complete situation which could result in overpayments.
