General Electronic Claims FAQs

How does the electronic submission process work?


  • Providers send electronic claims to CareFirst through one of our preferred vendors/clearinghouses.
  • The vendor/clearinghouse will edit all claims and send you a report to notify you of any errors they identify. Errors must be corrected and the claims must be resubmitted electronically.
  • Claims without errors are forwarded to CareFirst for processing and additional editing.
  • You will receive an additional report from the clearinghouse to confirm receipt of claims by CareFirst and advise you of any additional errors. Again, you have the opportunity to correct all errors and resubmit claims electronically.

How does my office begin submitting claims electronically to CareFirst?


  • If you do not currently have a vendor or clearinghouse, you may contact one of our preferred vendors.
  • If you currently work with another vendor or clearinghouse, you must contact that vendor to inquire about the enrollment process.
