Frequently Asked Questions

THIN/Electronic Claims

Q. Is additional information about reports available through THIN?
A. You can find a quick reference guide to THIN reports online. It provides the information necessary to navigate through all the reports currently available. You can select the reports you wish to receive.

Q. Can we send in a corrected billing electronically?
A. Corrected and Late Charge Facility claims may be filed electronically using the correct Type of Bill combination. For Professional Provider claims, we recommend that you complete the Physician and Provider Reconsideration and Appeal Form using the “Corrected Claim” option at this time. Once additional information is received from the Texas Department of Insurance, BCBSTX will notify you about how to submit corrected CMS 1500 claims electronically.

Q. Can you check eligibility on-line if you do not use THIN as your clearinghouse?
A. Yes. To do so, complete the Internet Enrollment (Claims Status and Eligibility) form.

Q. I received a new BCBSTX provider number, but I'm having problems filing electronically with this number. What do I need to do?
A. Contact the THIN EDI Helpline at 877-334-8446 or your THIN EDI Marketing Representative to ensure all of the proper paper work has been submitted and the new number has been activated for electronic billing.

Q. Will I still get a Provider Claim Summary (PCS) even if I elect to receive payment electronically?
A. Yes, you will continue to receive Provider Claim Summaries. The "E" in the check number easily identifies that the funds were electronically transferred.

Q. Since software programs needed to be HIPAA compliant by 10/16/2003, are all claims required to be HIPAA compliant?
A. THIN is still accepting claims even if they are not HIPAA compliant. THIN is in the process of contacting Vendors and Submitters to encourage compliance as quickly as possible.

Q. What is the difference between THIN EDI and ECARE?

Q. Can we get the claim number from our acceptance report for claims filed through THIN?
A. The first report received from THIN will not include the payer’s claim number. However, the second level reporting from the payer, generally sent three to four business days after the initial THIN acceptance report, includes an Internal Control Number (ICN). For BCBSTX PPO, POS and Indemnity claims, the ICN is the BCBSTX claim number. Although you will also receive an ICN number for HMO Blue Texas claims, this is not the claim number.

Q. Can a claim go through THIN without alpha prefix?
A. You may submit your claim to THIN, who will try to locate a membership record. If, however, a membership record cannot be found, the claim will be returned to you. BCBSTX recommends that you contact the appropriate Customer Service Department, found on the back of the member’s ID card, to obtain the correct alpha prefix for that date of service or obtain alternate claim filing instructions in the absence of the three digit alpha prefix.

Q. Who is responsible for claim edits?
A. THIN establishes edits based on HIPAA compliance requirements and payer claim processing requirements. This process allows you to correct and re-transmit rejected claims immediately, to avoid unnecessary delays. Software vendors may have edits in their software programs to ensure some level of completeness prior to transmission of claims to the clearinghouse/payer. It is very important for you to review your response files for warning and reject messages. If the message is a "Warning," the claim has been forwarded to the payer; however you should attempt to correct the error prior to your next submission. If the message is a "Reject," the claim WAS NOT forwarded to the payer; you should correct the error and resubmit that claim in your next transmission.

Q. What if a new CPT, ICD9, diagnosis code or modifier was created? How do we know if THIN accepts the code/modifier? Will it reject?

Q. What is the received date from the clearinghouse?
A. The received date is based upon when THIN accepts the claim. The payers received date is based upon when the payer received the claim from THIN.
