How can a CMS-1500 claim be electronically submitted, and what is the paper alternative?

• A. Electronically via an EDI file (e.g., 837P); the paper alternative is the traditional CMS-1500 form.
• B. Submit only by fax.
• C. Submit only by mail.
• D. Submit via email with encrypted attachment.

Answer: (A)

Electronic submission uses a HIPAA-compliant EDI transaction, specifically the 837 Professional format, to transmit a CMS-1500 professional claim's data to payers or clearinghouses. The paper alternative is the traditional CMS-1500 paper form, filled out and sent by mail (or submitted in person). The 837P format standardizes every data field, supports automated validation, and speeds processing, reducing manual entry errors. Submitting by fax or by encrypted email attachments isn’t the standard HIPAA electronic submission method, and while mail of the paper form is still possible as a non-electronic path, electronic transmission via 837P is the preferred route.
