HIPAA Compliance Guidelines for Email

To maintain HIPAA-compliant email communications, here’s a few unofficial guidelines to consider:

It’s best for covered entities to ask for patient consent before sending protected health information (PHI) over email. If a patient initiates communication with a healthcare provider through email, it can be assumed that future email communications are acceptable to the patient, unless stated otherwise. 


Ensure that emails containing PHI can only be accessed by authorized individuals, such as the patient, associated provider and associated professionals tasked with managing patient PHI. Also, ensure these emails include only the minimum amount of information necessary to communicate with the recipient.


Encryption and decryption should be utilized as a “reasonable and appropriate safeguard” to protect e-PHI where necessary for covered entities. Encrypting e-PHI isn’t required by HIPAA if an alternative measure already accomplishes this for a covered entity, but it is still a recommended feature to use when communicating via email.


How do I get HIPAA-compliant email?

HIPAA-compliant email tools can be obtained from a HIPAA-compliant email provider or developed independently in accordance with HIPAA standards and regulations.

What are the HIPAA rules for email?

Many HIPAA rules for email compliance are outlined under the Security Rule of HIPAA, which covers requirements to safeguard electronic protected health information (e-PHI).

As general practices for creating and sending HIPAA-compliant emails, it’s best to ask for patient consent before using email communications, establish authorized users for who can access PHI through email and to use email encryption.
