What Are the 5 Main HIPAA Rules?

HIPAA is a complicated piece of legislation that touches on every piece of the healthcare industry’s inner workings. While protecting patient health data is an important part of its mandate, it’s far from the whole story.

In this article, we’ll give you a broader understanding by outlining the five main HIPAA rules, how they work, what they aim to accomplish, and how role-specific online HIPAA training like ours can help your organization remain HIPAA compliant.

What Is HIPAA?

Before we begin our HIPAA rules explanation, let’s talk about what HIPAA is.

HIPAA stands for the Health Insurance Portability and Accountability Act, and for the most part, it’s a set of privacy and security rules in healthcare designed to protect sensitive patient information, or what we in the biz like to call "protected health information," or PHI for short.

HIPAA sets a few administrative and anti-fraud rules as well, but most people think of it as a privacy superhero, swooping in to make sure that your medical history, insurance details, and other confidential tidbits don't end up in the hands of the wrong people.

History of HIPAA

HIPAA was born out of a need for some serious healthcare reform in 1996. Healthcare providers were switching from paper records to electronic ones, which created larger vulnerabilities for data breaches and privacy breaches.

HIPAA also aimed to improve the accessibility and portability of health insurance coverage, making it easier for the average Joe to jump from one plan to another without losing sleep (or coverage).

A couple of decades later, it was time for another HIPAA update to account for new technology and strengthen privacy, security, and enforcement. 

The HIPAA Omnibus Final Rule of 2013 introduced four significant provisions that strengthened and expanded. These provisions:

  • Increased and tiered the civil money penalty structure for HIPAA violations.
  • Outlined a more objective harm threshold for breach notification rules.
  • Prohibited entities from disclosing or using genetic information to determine coverage or benefits.
  • Merged HIPAA with the Health Information Technology for Economic and Clinical Health (HITECH) Act to facilitate the switch to electronic records.

Rule 1: The Privacy Rule

If privacy is one of HIPAA’s superpowers, we should look carefully at the Privacy Rule.

The Privacy Rule sets the standards for who can access your health information, when they can access it, and how they can use it. It's about maintaining your dignity and privacy while still getting important information into the hands of the professionals that need it.

The principle underlying the specifics of the Privacy Rule is sometimes referred to as the HIPAA golden rule: handle patient information with the same level of confidentiality and respect you’d want your own data to be treated.

Covered entities are required to limit access to authorized parties and, even then, to the minimum amount of PHI necessary to perform the party’s role.

Health data privacy rules also give you the right to access your own medical records and receive copies in a timely manner. They also give you the right to request changes to your medical record or restrict certain disclosures.

Rule 2: The Security Rule

The Privacy Rule’s disclosure restrictions don’t mean much unless your data is also sufficiently secured against unauthorized access. That’s where the Security Rule comes in.

Its goal is to protect the confidentiality, integrity, and availability of electronic PHI (ePHI). It does so by setting forth requirements and safeguards that healthcare providers and organizations must adhere to. These guidelines are not one-size-fits-all. They take into account the size, complexity, and capabilities of each organization.

First, the Security Rule mandates the implementation of safeguards to protect against any unauthorized access, use, or disclosure of your digital health information. It's like constructing a digital fortress around your ePHI, complete with firewalls, encryption, and access controls. No creeper is getting through those virtual gates!

Second, organizations are required to conduct regular risk assessments to identify and address any potential vulnerabilities. This is important because technology is always evolving, and it’s necessary for HIPAA-compliant entities to stay one step ahead of the bad guys if they hope to ensure that your ePHI remains secure.

To see the Security Rule in action, let's consider a scenario. Imagine a small-town clinic that falls victim to a ransomware attack. The hackers try to hold their ePHI hostage, demanding a hefty payout to release it. If the clinic has been following HIPAA compliance guidelines and best practices, it keeps secure backups of its data, uses strong encryption, and has incident response protocols ready to implement for just this scenario. Security Rule to the rescue!

The Breach Notification Rule

The Breach Notification Rule was added in 2013 as part of the HITECH Act mentioned earlier. It added to the Security Rule by setting requirements for what to do once a breach has occurred. It defines breaches, outlines notification requirements, and provides procedures for investigation and notification, thereby putting power back in your hands.

Security Breaches can be anything from a case of medical information being sent to the wrong address to the broad healthcare cyberattacks that are becoming increasingly commonplace.

Regardless of the degree, if a breach occurs, your healthcare provider or organization must conduct a thorough investigation to assess the risk. They'll evaluate the nature and extent of the breach and the likelihood that your protected health information has been compromised.

Then they’re legally obligated to notify you in a timely manner so you’re aware that sensitive information may have been compromised. By doing so, the Breach Notification Rule empowers you to take the necessary steps to protect yourself.

Rule 3: Transactions and Code Sets Rule

The Transactions and Code Sets Rule is all about the secret language by which electronic health data is passed between systems. It standardizes the way information is encoded and passed along, making it easier for accurate and complete data to move efficiently and reliably from one system to another.

The “Transactions” part of the rule standardizes the process for sending electronic healthcare data transactions like claims, enrollment, and payment information to ensure accurate, secure, and efficient communication.

The “Code Sets” portion of the rule tackles the tricky task of creating simple codes to transmit complex medical information. It requires everyone to translate all diagnoses, medical conditions, procedures, services, items, supplies, and medications into a handful of numbers and letters by using specific sets of uniform codes. These codes streamline communication and facilitate accurate billing and reimbursement.

It sounds nitpicky, but the Transaction and Code Set Rule helps reduce errors and improve billing processes, which ultimately enhances the quality of your care.

Rule 4: Unique Identifiers Rule

The Unique Identifiers Rule is a critical component of HIPAA, aimed at assigning unique identification numbers to healthcare providers, health plans, and employers. Just as code sets add clarity to diagnostic and treatment information, unique identifiers provide a bulletproof way to distinguish between different healthcare entities.

For example, healthcare providers are assigned a unique 10-digit number referred to as a National Provider Identifier (NPI). This keeps identity crystal clear even when providers have similar names. Similarly, health plans receive Health Plan Identifiers (HPIDs).

Covered entities must use their standardized identifiers when conducting various healthcare transactions to ensure that information gets to the right organization and the recipient understands exactly where it comes from.

Rule 5: The Enforcement Rule

Rules never matter unless they’re enforced, so the final rule you need to know about is the Enforcement Rule. It’s all about holding healthcare organizations accountable and making sure they toe the line when it comes to following all the other rules.

The primary authority in HIPAA enforcement is the Department of Health and Human Services’ Office for Civil Rights (OCR). They have the power to investigate complaints, conduct audits, and impose penalties.

Non-compliance is not taken lightly in the world of HIPAA. The OCR has the power to dish out fines ranging from thousands to millions of dollars, depending on the severity of the violation.

When HIPAA violations rise to the level of deliberate neglect or personal gain, the OCR can refer the case to the Department of Justice so they can file criminal charges.

Enforcement like this motivates everyone to follow essential privacy and security rules in healthcare.  Even if a small-town physician practice thinks of health data privacy rules as a nuisance, they know there will be consequences if they don’t meet HIPAA compliance guidelines. To avoid fines and bad press, they’ll put effort into understanding HIPAA regulations and keeping your PHI private and secure.

Every investigation that hits the news is a wake-up call to other organizations, reminding them to protect your privacy.
