Healthcare IT Auditing and HIPAA Compliance
Learn how to audit healthcare IT systems for HIPAA compliance. Understand key security and privacy requirements for the CISA exam.
HIPAA and Healthcare IT Auditing
The Health Insurance Portability and Accountability Act (HIPAA) establishes national standards for protecting patient health information. For CISA candidates, understanding HIPAA auditing is important because healthcare is one of the most heavily regulated industries for information protection, and HIPAA compliance is a common audit focus area.
HIPAA Key Components
HIPAA includes several rules that affect IT auditing:
- Privacy Rule: Establishes standards for the use and disclosure of Protected Health Information (PHI). It defines patient rights, minimum necessary standards, and notice of privacy practices requirements.
- Security Rule: Requires administrative, physical, and technical safeguards to protect electronic PHI (ePHI). This is the primary focus of IT auditing.
- Breach Notification Rule: Requires covered entities to notify affected individuals, the Department of Health and Human Services, and in some cases the media when a breach of unsecured PHI occurs.
- Enforcement Rule: Establishes procedures for investigations and penalties for HIPAA violations.
Security Rule Safeguards
The HIPAA Security Rule requires three categories of safeguards:
- Administrative safeguards: Security management processes, assigned security responsibility, workforce security, information access management, security awareness training, security incident procedures, contingency planning, and periodic evaluation.
- Physical safeguards: Facility access controls, workstation use policies, workstation security measures, and device and media controls.
- Technical safeguards: Access controls including unique user identification, emergency access procedures, automatic logoff, and encryption. Audit controls for recording and examining system activity. Integrity controls for protecting ePHI from improper alteration. Person or entity authentication. Transmission security including encryption for data in transit.
Required vs. Addressable Specifications
HIPAA distinguishes between required and addressable implementation specifications. Required specifications must be implemented. Addressable specifications must be assessed, and the organization must either implement the specification, implement an equivalent alternative measure, or document why it is not reasonable and appropriate to implement the specification.
HIPAA Risk Analysis
A HIPAA risk analysis is the foundation of compliance and involves identifying all systems that create, receive, maintain, or transmit ePHI, identifying threats and vulnerabilities to those systems, assessing the likelihood and impact of potential risks, determining the appropriate level of risk the organization can tolerate, and implementing security measures to reduce risks to acceptable levels.
Auditing HIPAA Compliance
IS auditors evaluating HIPAA compliance should verify that a comprehensive risk analysis has been conducted and is regularly updated, that required safeguards are implemented, that addressable safeguards are properly assessed and documented, that business associate agreements are in place with all third parties handling PHI, that breach notification procedures are established and tested, and that workforce training on HIPAA requirements is conducted regularly.
CISA Exam Focus
For the CISA exam, understand the structure of HIPAA (Privacy Rule, Security Rule, Breach Notification Rule), the three categories of security safeguards, the difference between required and addressable specifications, and the role of risk analysis in HIPAA compliance. Questions may present healthcare scenarios and ask about appropriate safeguards or audit findings.
