The Importance of Encryption for HIPAA Compliance

Encryption. . .what does it mean to encrypt something? Why is it important? And why is it particularly important for covered entities and business associates in the health services industry? What can you do to make sure your data is encrypted while it is being transferred from one place to another and while it is at rest on servers and backup drives? These are all questions I am asked regularly when I do initial HIPAA risk assessments and audits. My clients tend to downplay the importance of encryption initially until they fully understand the risks of not encrypting data properly.

Encryption is defined as the translation of data into a secret code. Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. If you were to send a file across the internet in a non-encrypted format, it could be intercepted anywhere along the way and you would have no idea that your data had been breached. Additionally, if you were to store data on a storage device in a non-encrypted format, and that device was lost or stolen, your data would be accessible to anyone. Using encryption nullifies both of those scenarios by only allowing someone with your secret encryption key to decrypt the data and read it.

For the purposes of HIPAA compliance, encryption is absolutely necessary for one particular category of data: protected health information (PHI). This includes patient medical records, personal patient information like phone numbers, addresses, and social security numbers. Encryption of PHI is important for a few reasons. First, and foremost, you have a duty to your patients to keep their personal information safe from unauthorized access. One quick way to lose patients and your practice is to betray patient trust. Additionally, as a covered entity or business associate you are bound by federal law to protect PHI from breach or loss. The Office of Civil Rights has the authority to fine you up to $50,000 per record breached or lost if they deem that you haven’t implemented and followed a good faith HIPAA compliance plan.

During our HIPAA audits we most commonly find that practices aren’t employing encryption when emailing patient health records to other practices or to the patients themselves. This is a fairly easy problem to fix. There are a multitude of available email encryption services such as Virtru, Office 365 Encrypted Email, and Hushmail. These services generally integrate directly into your browser or Microsoft Outlook so that it’s as easy as pressing a button to convert any email into an encrypted email that requires the user at the other end to verify their identity to receive the email.

It is more complicated to find out if the other two categories have HIPAA compliant encryption enabled. These two areas are data stored on devices like servers, desktops, laptops, and mobile phones. And separately, data stored on backup devices and backed up to the cloud. You will want to contact a HIPAA compliant IT specialist to verify that your devices and backup storage is HIPAA compliant. An IT specialist can tell you what level of encryption you are using and whether the encryption is turned on and configured properly. Additionally, in the case of a cloud backup service, the IT specialist can make sure that the cloud provider is HIPAA compliant themselves and is willing to sign a Business Associate Agreement (BAA) for your practice and share some of the liability for storing that sensitive data.

J.J. Micro IT Consulting is available for a free HIPAA risk assessment. During that assessment we will look for proper encryption methods in addition to possible HIPAA compliance issues in the categories of security, privacy, and administrative procedures.
