Reminder: Initial Treatment Dates on ANSI v5010
As a reminder, the ANSI Version 5010 format for electronic claims no longer has a field for the date your patient was first treated for a particular condition by you or a referring physician. However, you may receive a letter from Blue Cross and Blue Shield of Oklahoma (BCBSOK) requesting this additional information.
When you receive this letter, you may submit the requested information to BCBSOK in one of the following ways:
- Electronic (preferred method) — Fill in the date and fax the letter to the number indicated on the letter
- Phone — Call the Customer Service number indicated on the letter to provide the date over the phone
- U.S. Mail — Fill in the date and mail to the return address indicated on the letter
If you utilize a billing service or clearinghouse to submit electronic claims on your behalf, please check with them to ensure they are aware of the above information.
We appreciate your patience and cooperation.
