Electronic Claims

  • Advantages include greater security and accuracy of data, along with faster processing and payment.
  • Claims may be submitted one-at-a-time by entering information directly into an online claim form on the vendor portal; or batch claims may be submitted via your Practice Management System (check with your software vendor to ensure compatibility).
