HIPAA (Health Insurance Portability and Accountability Act) sets the rules for how protected health information (PHI) must be handled. When you automate healthcare workflows, every system that touches patient data needs to comply with HIPAA's Privacy Rule, Security Rule, and Breach Notification Rule.
In practice, this means several things for automation projects:
Data residency:
PHI should be processed on infrastructure you control or that's covered by a Business Associate Agreement (BAA). This is why self-hosted automation tools like n8n are preferred over cloud-only platforms for healthcare workflows — your patient data stays on your infrastructure.
Access controls:
Automated systems need the same role-based access controls as human users. An automation that checks insurance eligibility shouldn't have access to clinical notes it doesn't need.
Audit trails:
Every automated action involving PHI needs to be logged — what data was accessed, when, by which system, and what action was taken. This is where many DIY automation attempts fall short.
Encryption:
Data in transit and at rest must be encrypted. API calls to EHRs must use TLS. Stored data must be encrypted on disk.
Minimum necessary:
Automations should only access the minimum PHI needed for their specific function. An appointment reminder automation needs the patient name, phone number, and appointment time — not their full medical history.
I'm CPHIMS certified and have worked on Medicare Advantage programs, so I build automations with these requirements baked in from the start rather than retrofitting compliance after the fact.
