158 - Entity's date of birth. Usage: This code requires use of an Entity Code.

This error indicates the Date of Birth (DOB) for the Member (the subscriber) on the claim does not match the Date of Birth in their system.

Many payers are moving towards verification of the date of birth that you send on the claim.  If you are not already doing so, you should make it a practice to get the insured's (subscribers) date of birth on intake and enter it on the insurance card in Therabill.   This will help minimize these rejections.

How to Fix

You will need to edit the insurance card in Therabill and add the correct date of birth. 

IMPORTANT: If the patient and the subscriber are the same (if you have the relation set to self on the insurance card) then make sure to update the client/patient date of birth as well.

Resubmitting the claim 

Once you have made the required edits, from the error page, you can then click the Resubmit Electronically button at the top to send the claim out with the new information.
