Okay, I think someone somewhere along the line is misconstruing something - the patient, the biller, me...either that or other states' carriers handle their w/c claims differently that the carriers in Texas do.

In Texas, to successfully bill a w/c claim you need these MINIMUM elements:

The DOI
The SSN
The claim number and/or the employer's name, address and policy number
A dx that matches the injury

In the above scenario there's no way ANY but one or possibly two of those elements could have been satisfied.
