Towards a HIPAA Compliant Agentic AI System in Healthcare
This paper introduces a HIPAA-compliant Agentic AI framework designed for healthcare, integrating Attribute-Based Access Control (ABAC), a hybrid PHI sanitization pipeline, and immutable audit trails. It aims to address critical regulatory compliance challenges posed by autonomous AI systems handling Protected Health Information (PHI) in clinical workflows, ensuring data privacy and security while leveraging AI for tasks like diagnosis prediction and medical report generation.
Executive Impact & Strategic Value
Understand the core challenges and the transformative potential of a HIPAA-compliant Agentic AI framework in healthcare operations.
Core Challenge
Ensuring strict HIPAA compliance, particularly regarding Protected Health Information (PHI), for autonomous Agentic AI systems operating in healthcare. Traditional access controls struggle with unstructured clinical data, and LLM-driven workflows risk PHI exposure, memorization, and bypassing rules.
AI-Powered Solution
A novel HIPAA-compliant Agentic AI framework integrating three core mechanisms: dynamic, context-aware Attribute-Based Access Control (ABAC); a hybrid PHI sanitization pipeline (regex + BERT-based model) for minimal PHI leakage; and immutable audit trails for compliance verification.

Dynamic PHI Governance with ABAC
The framework leverages Attribute-Based Access Control (ABAC) to dynamically govern access to PHI. Unlike traditional role-based models, ABAC evaluates subject attributes (e.g., user roles), resource attributes (e.g., data sensitivity), action types (e.g., read/write), and environmental attributes (e.g., time, network security) to enforce least-privilege access. Policies are defined using first-order logic and enforced through a distributed architecture of policy agents.
This ensures that access decisions are granular and context-aware, adhering to HIPAA's Minimum Necessary Standard.
Hybrid PHI De-identification Pipeline
A critical component is the hybrid PHI sanitization pipeline that combines rule-based regex patterns and a BERT-based model fine-tuned in clinical corpora. Regex handles structured identifiers (e.g., SSN, MRN) with deterministic pattern matching, while the BERT model identifies contextual PHI (e.g., patient names, diagnoses) in unstructured text, complying with HIPAA's Safe Harbor and Expert Determination rules.
Dual redaction stages (pre- and post-inference) minimize PHI exposure, ensuring data privacy before LLM processing and after output generation.
Immutable Compliance Verification
The framework implements immutable audit trails through a dual logging architecture, based on NIST 800-66r2. Interaction logs record sanitized user queries, policy decisions, and redaction actions. Both raw LLM outputs and sanitized versions are stored for forensic investigations. Decision logs form an immutable ledger of access decisions, secured via cryptographic hashing to prevent tampering. This fulfills HIPAA's 6-year retention mandate and ensures accountability.
