AI Governance for Healthcare: Protecting PHI in the Age of Copilot and ChatGPT

Healthcare organizations are adopting AI at speed — clinicians drafting notes with Copilot, staff summarizing documents in ChatGPT, and vendors embedding AI into everyday tools. The productivity gains are real. So is the risk: protected health information (PHI) can move into AI platforms that were never covered by a business associate agreement, creating exposure that is invisible until it becomes an incident.

Why healthcare is uniquely exposed

Three characteristics make AI governance especially urgent in healthcare:

• Regulated data everywhere. PHI flows through email, documents, chat, and clinical systems — all of which now have AI features.

• High breach cost. Healthcare consistently ranks among the most expensive sectors for data breaches, before regulatory penalties.

• Distributed workforce. Clinical and administrative staff adopt tools independently, often without security review.

The governance goal: enable AI without exposing PHI

Effective healthcare AI governance is not about blocking AI. It is about ensuring that regulated data does not flow into ungoverned tools, while still letting staff benefit from approved ones. That requires answering four questions with evidence, not assumptions:

• Which AI tools are staff actually using, and on which devices?

• Is PHI or other sensitive data being entered into them?

• Which tools are covered by appropriate agreements, and which are not?

• Can we enforce policy at the point of use — block, mask, or alert — rather than relying on training alone?

Connecting AI governance to HIPAA

HIPAA does not mention ChatGPT, but its requirements around safeguarding electronic PHI, access controls, and audit trails map directly onto AI usage. Demonstrating that you can see where PHI moves, restrict unsanctioned tools, and produce an audit trail is exactly the kind of evidence that supports compliance and reassures leadership and boards.

A practical starting point

Regent Arc gives healthcare organizations visibility into AI usage and sensitive data exposure across the tools employees actually use, then enforces governance policies before PHI leaves trusted environments. Paired with a focused assessment, it turns AI risk from an unknown into a managed, documented control.
