The Health Insurance Portability and Accountability Act (HIPAA) is a U.S. law signed on August 21, 1996, that sets national standards for protecting sensitive patient health information. HIPAA was created to ensure that personal medical records remain private, secure, and accessible only to authorized individuals, while still allowing patients to access their own data.
Before HIPAA, most healthcare records were stored in paper form, and there were no federal laws regulating how health data could be shared or protected. As the healthcare industry shifted toward electronic systems in the 1990s, lawmakers recognized the need to secure digital records while keeping them available for patient care.
Since its adoption, HIPAA compliance has evolved through major updates to address new technologies and cybersecurity risks. In this article, we’ll explain how HIPAA has changed over time, why it matters for healthcare and data security, and share practical tips for staying compliant.

Since its adoption, HIPAA has evolved through major updates to address new technologies and cybersecurity risks. In this article, we’ll explain how HIPAA has changed over time, why it matters for healthcare and data security, and share practical tips for staying compliant.
HIPAA Privacy Rule
The HIPAA Privacy Rule, officially called the Standards for Privacy of Individually Identifiable Health Information, is one of the most important parts of HIPAA. It was created to establish a national standard for protecting patient health information (PHI). The rule became mandatory in April 2003.
The HIPAA Privacy Rule gives patients greater control over their medical records and sets clear limits on how their information can be used or shared. Specifically, it:
-
Allows individuals to access and request copies of their health records.
-
Defines who can access PHI, when it can be accessed, and under what circumstances it can be shared.
-
Applies broadly to all healthcare providers, health plans, and healthcare clearinghouses that handle PHI or electronic PHI (ePHI).
In short, if your organization operates in the healthcare industry and deals with patient information, the HIPAA Privacy Rule applies to you.
HIPAA Security Rule
The HIPAA Security Rule, officially called the Security Standards for the Protection of Electronic Health Information, was finalized in 2003 with a compliance deadline of April 2005. It was developed alongside the HIPAA Privacy Rule to ensure stronger safeguards for electronic protected health information (ePHI).
Unlike the Privacy Rule, which focuses on who can access health data, the Security Rule provides a framework for protecting ePHI from theft, loss, or unauthorized access. Instead of prescribing rigid steps, it allows organizations flexibility in how they meet security requirements, as long as compliance is maintained.
The HIPAA Security Rule is built around three key safeguard categories:
-
Administrative safeguards – policies, procedures, and workforce training to protect ePHI.
-
Physical safeguards – facility and device protections to prevent unauthorized access.
-
Technical safeguards – technology-based controls such as encryption and access authentication.
Together, these safeguards help healthcare organizations establish a strong defense against cyber threats while keeping patient data secure and accessible.
HIPAA Breach Notification Rule
The HIPAA Breach Notification Rule, officially called the Interim Final Rule for Breach Notification for Unsecured Protected Health Information, went into effect in September 2009. It requires covered entities—such as healthcare providers, health plans, and their business associates—to notify the Secretary of Health and Human Services (HHS) when a breach of unsecured protected health information (PHI) occurs.
The rule remains in effect as an interim regulation until a final version is adopted, but its requirements are fully enforceable.
Key Breach Notification Requirements
-
Breaches affecting 500 or more individuals: Must be reported to HHS within 60 days of discovering the breach.
-
Breaches affecting fewer than 500 individuals: Must be reported to HHS no later than 60 days after the end of the calendar year in which the breach was discovered.
In both cases, organizations must notify impacted individuals directly and take steps to mitigate potential harm.
HIPAA Enforcement Rule
The HIPAA Enforcement Rule gives regulatory authority to enforce HIPAA compliance and hold organizations accountable for violations. It designates the Office for Civil Rights (OCR) within the Department of Health and Human Services (HHS) as the agency responsible for civil enforcement, while the Department of Justice (DOJ) handles criminal cases.
When it was first introduced, enforcement was limited. However, the HITECH Act of 2009 significantly strengthened the Enforcement Rule by giving OCR the ability to issue larger penalties and increase oversight of covered entities and business associates.
Today, enforcement actions are much more common. OCR regularly issues resolution agreements, fines, and corrective action plans for organizations that fail to comply with HIPAA requirements. Penalties can range from thousands to millions of dollars, depending on the severity of the violation or data breach.
HITECH Act
The Health Information Technology for Economic and Clinical Health (HITECH) Act was enacted in February 2009 as part of the American Recovery and Reinvestment Act (ARRA). Its purpose was to promote the adoption of electronic health records (EHRs) and strengthen the enforcement of HIPAA compliance.
One of the most important impacts of the HITECH Act was a major increase in penalties for HIPAA violations. The law gave the Office for Civil Rights (OCR) more authority to investigate and fine organizations that fail to protect patient data.
Key provisions of the HITECH Act include:
-
Stronger penalties – substantially higher fines for HIPAA violations.
-
Expanded enforcement – State attorneys general were given the authority to bring HIPAA cases in addition to federal regulators.
-
Focus on electronic health records (EHRs) – incentivized the shift toward secure digital record-keeping.
Overall, the HITECH Act marked a turning point for HIPAA by making enforcement more rigorous and ensuring that organizations take data privacy and security seriously.
HIPAA Omnibus Rule

The HIPAA Omnibus Rule, which took effect in March 2013, represents the most comprehensive update to HIPAA law. It consolidated the Privacy Rule, Security Rule, Breach Notification Rule, Enforcement Rule, and the HITECH Act into one final regulation.
The Omnibus Rule was designed to finalize earlier interim rules and create a durable framework for protecting patient data. It also provided extensive clarification on the intent behind specific HIPAA changes, giving covered entities clearer compliance guidance.
Key impacts of the HIPAA Omnibus Rule include:
-
Integration of multiple rules into a single, enforceable standard.
-
Significant updates to the HIPAA Privacy Rule — expanding patient rights and tightening limits on disclosures.
-
Expanded enforcement under the HIPAA Enforcement Rule — strengthening penalties for noncompliance.
-
Refinements to the Security Rule to address evolving risks to electronic protected health information (ePHI).
In short, the HIPAA Omnibus Rule is the version of HIPAA that healthcare providers and business associates must follow today, serving as the foundation for modern compliance.
HIPAA Compliance Today
The HIPAA law has grown significantly since 1996. Today, compliance is required for any organization that qualifies as a covered entity or business associate. In practice, this includes nearly everyone who works with patient data in the healthcare industry.
Covered entities include:
-
Health plans – insurance companies, HMOs, employer-sponsored health plans, Medicare, and Medicaid.
-
Healthcare providers – doctors, psychologists, dentists, pharmacies, and anyone who delivers treatment.
-
Healthcare clearinghouses – organizations that process or manage health information.
Business associates are any third parties that handle PHI or ePHI on behalf of a covered entity, such as IT providers, billing services, or data storage companies.
Why HIPAA Compliance Matters
Compliance with HIPAA is critical for two reasons:
-
Protecting patient data – safeguarding electronic protected health information (ePHI) against data breaches, ransomware, and unauthorized access.
-
Avoiding penalties – the Office for Civil Rights (OCR) can impose fines of up to $50,000 per violation and as much as $1.5 million per year. Even unintentional violations are subject to penalties under the HIPAA Omnibus Rule.
OCR may also conduct audits of covered entities and business associates to verify compliance with the HIPAA Privacy Rule, Security Rule, and Breach Notification Rule.
The Role of Third-Party HIPAA Assessments
Organizations without a dedicated compliance team should consider working with a third-party HIPAA compliance assessor like RSI Security. External assessors help by:
-
Conducting HIPAA compliance assessments and preparing audit checklists.
-
Reviewing systems, processes, and data handling against HIPAA Security Rule requirements.
-
Performing risk assessments and penetration testing to identify vulnerabilities before attackers do.
-
Training staff and building processes to maintain long-term compliance.
The Risks of Non-Compliance
Non-compliance goes beyond financial penalties. Healthcare organizations face rising threats such as:
-
Ransomware attacks that lock patient records until ransoms are paid.
-
Data breaches that cause lasting reputational and financial damage.
-
Growing attack surfaces from connected medical devices and digital systems.
Maintaining HIPAA compliance is an ongoing effort, requiring skilled staff, regular assessments, and proactive security measures. With the right support, organizations can stay compliant, avoid costly fines, and keep patient data secure.
