TriWest Region 4 Payor ID#




  • Sara

    Hi Dixie,

    To get started, scan or photograph your client's insurance ID card for reference. You can then upload it to the client's file for safe keeping

    Read the front and back of the client's ID card to see if there are any special online filing instructions indicating what company claims should be sent to. If there are no special instructions, you'll file claims with the insurance company printed on the front of the ID card.

    To locate the appropriate payer ID:

    • Start by looking at your client's insurance member ID card to see if there is a payer ID listed on it. This is often listed on the backside of a client's member ID under Claim Filing information (but it can also be listed on the front side of the card).
    • You can then search our system for this payer by typing that payer ID into the Insurance Company field in the client's Billing and Insurance settings page as well as by searching in the Insurance list.

    Finding a Payer ID for Payers not listed in our system is also done manually and I've included a guide on that as well: How do I find the correct payer ID?

    What is the outcome of this as I too have been searching for Triwest Region 4 and haven't been able to find it in the listings? Need to be able to do their claims electronically as its required with my contract. So mailing and faxing because I've added it isn't an option.

    I was told to bill it to TriWest VACCN Region 5 (TWVACCN) and it will get there.

    But you have to enroll TriWest VACCN Region 5 (TWVACCN) with the Clearing House for Simple Practice which is called "Eligible"

    You should call TriWest and explain the down time with setting up EDI through your clearing house and ask if you can mail or fax until it is set up.

    Hope this helps!
