Twilio has introduced its Business Associate Addendum (BAA) to support HIPAA-compliant communications use cases, allowing customers to build health and communications applications with Protected Health Information (PHI). The BAA is structured as an addendum to Twilio's standard terms of service or master sales agreement and focuses on the additional requirements needed for HIPAA compliance. Customers are responsible for ensuring their software applications' instructions comply with applicable laws, while Twilio is responsible for providing information sufficient for compliance and executing instructions faithfully in a secure manner. The BAA applies to specific projects and subaccounts that process PHI, and its scope is continuously expanding as more Twilio products become HIPAA-eligible.
