Initial Treatment Dates on ANSI v5010

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 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.
