HIPAA stands for the Health Insurance Portability and Accountability Act. It is a federal law signed by President Bill Clinton on August 21, 1996. HIPAA establishes national standards for protecting sensitive patient health information — known as protected health information (PHI) — from being disclosed without a patient’s knowledge or consent.
The law is administered and enforced by the U.S. Department of Health and Human Services (HHS), specifically through its Office for Civil Rights (OCR).
Breaking Down the HIPAA Acronym
| Letter | Word | What It Means |
| H | Health | Applies to health information and the healthcare industry |
| I | Insurance | Originally focused on health insurance portability between jobs |
| P | Portability | Workers could carry health coverage when changing employers |
| A | Accountability | Establishes standards for protecting patient data and punishing violations |
| A | Act | Federal legislation passed by Congress |
What Was HIPAA Originally Designed to Do?
When HIPAA was passed in 1996, its primary purpose was not data privacy — it was health insurance portability. The law was designed to ensure that Americans could maintain their health insurance coverage when changing or losing jobs.
The data privacy and security standards that HIPAA is most known for today came later, through two major rules:
- The HIPAA Privacy Rule (2003) — established national standards for protecting PHI, giving patients greater control over how their health information is used and disclosed
- The HIPAA Security Rule (2005) — introduced administrative, physical, and technical safeguards for protecting electronic PHI (ePHI)
- The HITECH Act (2009) — strengthened HIPAA enforcement, expanded breach notification requirements, and increased accountability for healthcare organizations
- The HIPAA Omnibus Rule (2013) — extended HIPAA requirements to business associates and strengthened patients’ privacy rights
In late 2024, HHS proposed the most significant update to the HIPAA Security Rule in over two decades. The proposed rule, formally published in early 2025, would make cybersecurity requirements more prescriptive — requiring safeguards such as multifactor authentication, encryption, vulnerability management, and stronger risk analysis. As of July 2026, the final rule has not yet been issued.

What Does HIPAA Protect?
HIPAA protects Protected Health Information (PHI) — any information that can be used to identify a patient and relates to their health condition, healthcare treatment, or payment for healthcare services.
PHI includes:
- Names, addresses, dates of birth
- Social Security numbers
- Medical record numbers
- Health plan beneficiary numbers
- Account numbers
- Certificate or license numbers
- Phone and fax numbers
- Email addresses
- IP addresses
- Photos
- Any other unique identifying number or code
PHI can exist in any format — paper, electronic (ePHI), or spoken. All three are protected under HIPAA.
Who Does HIPAA Apply To?
HIPAA applies to two categories of organizations:
Covered Entities — organizations that directly handle PHI:
- Healthcare providers (hospitals, clinics, physicians, dentists, therapists)
- Health plans (insurance companies, HMOs, employer health plans)
- Healthcare clearinghouses (entities that process health data between providers and payers)
Business Associates — third-party vendors that handle PHI on behalf of covered entities:
- Cloud hosting providers
- Electronic health record (EHR) vendors
- Billing companies
- IT service providers
- Legal and accounting firms with access to PHI
As Gil Vidals, CTO and co-founder of HIPAA Vault, explains:
“A lot of people think HIPAA only applies to hospitals and doctors. But if you’re a software company, a hosting provider, a billing service — anyone who touches that data — you’re a business associate, and you have to sign a BAA and meet the same standards.”
Any business associate must sign a Business Associate Agreement (BAA) with the covered entity before handling PHI. Without a BAA, using a vendor — whether a cloud platform, email service, or video conferencing tool — is a direct HIPAA violation.

Learn MoreWhat Are the HIPAA Rules?
HIPAA is not a single rule — it is a set of regulations administered under the original Act:
1. The Privacy Rule Establishes patient rights over their health information and limits how covered entities can use or disclose PHI. Patients have the right to access their records, request corrections, and receive a notice of privacy practices.
2. The Security Rule Requires covered entities and business associates to implement administrative, physical, and technical safeguards to protect ePHI. This includes encryption, access controls, audit logging, and regular risk assessments.
3. The Breach Notification Rule Requires covered entities to notify affected individuals, HHS, and in some cases the media within 60 days of discovering a data breach involving unsecured PHI.
4. The Omnibus Rule Extended HIPAA obligations directly to business associates and their subcontractors, and strengthened enforcement penalties.
5. The HITECH Act While technically separate legislation, HITECH is closely tied to HIPAA. It introduced meaningful use requirements for electronic health records and significantly increased HIPAA penalties.
What Are the Penalties for HIPAA Violations?
HIPAA violations can result in substantial civil penalties enforced by the U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR). Civil penalties are based on the organization’s level of culpability:
| Violation Category | Civil Penalty Range |
| Did not know | $100–$50,000 per violation |
| Reasonable cause | $1,000–$50,000 per violation |
| Willful neglect (corrected) | $10,000–$50,000 per violation |
| Willful neglect (not corrected) | $50,000 per violation |
Annual penalty limits are adjusted periodically for inflation by HHS.
In addition to civil penalties, serious HIPAA violations may also result in criminal charges, with fines of up to $250,000 and prison sentences of up to 10 years for offenses involving malicious intent or personal gain.
Beyond regulatory enforcement, organizations may face investigations by state attorneys general, contractual liabilities, litigation, breach notification costs, and reputational damage.
According to IBM’s 2025 Cost of a Data Breach Report, healthcare has remained the most expensive industry for data breaches for the 14th consecutive year, with the average healthcare breach costing $7.42 million.
HIPAA vs HIPPA — Which Is Correct?
HIPAA is the correct spelling. “HIPPA” is a common misspelling — it has no official meaning and is not a law or regulation. Both spellings are widely searched online, but only HIPAA is correct.
