Answer:
The correct answer would be option D, Confirm with the provider.
Step-by-step explanation:
A medical biller is a person who sends medical claims to the insurance companies. A medical biller is responsible for making the document ready to be sent to the payer of the claims. There should be no mistake in the file which is to be sent, so it is the duty of the medical biller to see for them, and if the biller notices that there is something incomplete in the document which is to be sent to the payer or insurance company for claim, then the biller should confirm this from the document provider and complete the document and then send to the company for claim.
