HIPAA Messaging Requirements

Choosing a platform that claims HIPAA compliance is step one. You must also configure it correctly and maintain documentation. Use our risk assessment template to evaluate your messaging setup per 45 CFR §164.312.

Signed BAA with the messaging vendor

Critical

A Business Associate Agreement must be executed before any PHI is sent through the platform. Encryption alone does not equal compliance without a BAA.

Encryption in transit and at rest

Critical

Messages containing PHI must be encrypted with AES-256 (or equivalent) both during transmission and when stored on the vendor's servers.

Access controls and authentication

Required

Unique user credentials, automatic session timeouts, and remote wipe capability for lost devices. MFA is strongly recommended and may become mandatory under proposed 2026 rules.

Message retention and disposal policies

Required

Define how long messages are retained and how they are securely deleted. Some platforms offer configurable auto-expiry, which helps minimize PHI exposure.

Audit logging for all PHI access

Required

HIPAA requires a record of who accessed PHI and when. Ensure your messaging platform logs message delivery, read receipts, and file access events.
