Providers can submit claims-related attachments via EDI healthcare claim attachment 275 transactions

Effective August 26, 2022, providers can submit claims related attachments via electronic data interchange (EDI) healthcare claim attachment 275 transactions. Sending attachments electronically offers a faster, more streamlined and cost-efficient process over mailing paper attachments on a paper submission. Examples of attachments are certificates of medical necessity (CMN), discharge summaries and reports to support a claim adjudication.

California Health & Wellness Plan (CHWP) teamed up with Availity® to offer a platform where healthcare providers and health plans can electronically submit claims-related attachments.
