Encrypting an email is a component of achieving HIPAA compliance, but it's not the sole requirement. While email encryption helps protect the content of the message from unauthorized access during transmission, HIPAA compliance encompasses a broader set of standards and safeguards related to the privacy and security of protected health information (PHI).

Email encryption is the process of encoding the content of an email message in a way that makes it unreadable to anyone except the intended recipient. This is accomplished using encryption algorithms and keys. Email encryption ensures that even if an unauthorized person intercepts the email during transmission, they cannot decipher the information. That ensures HIPAA compliant email communication.
While email encryption protects all content in emails, HIPAA is designed to ensure the privacy and security of PHI. The HHS states that "The Privacy Rule allows covered health care providers to communicate electronically, such as through e-mail, with their patients, provided they apply reasonable safeguards when doing so.". That includes access controls, user authentication, training and education, consent, and business associate agreements (BAAs). When taken together, these components create a comprehensive framework for safeguarding PHI.

There are limitations to relying solely on email encryption for HIPAA compliance. Email encryption primarily addresses the security of the email content during transmission. However, it does not cover all aspects of compliance.
For instance, encrypting an email does not guarantee that the email recipient is authorized to access the PHI it contains. It also doesn't address the risk of human error, such as sending an email to the wrong recipient or including PHI in the subject line.
Additionally, HIPAA compliance is not just about securing the content of email messages; it extends to secure email access, storage, and disposal practices. To be fully compliant, organizations must have policies and procedures determining how email accounts are accessed, who has access, and how PHI is handled at every stage of its lifecycle.

Personal email accounts should not be used for sending PHI. Only secure, HIPAA compliant email systems should be used to ensure appropriate safeguards are in place.
A BAA is a contract between a HIPAA covered entity and a third-party service provider that ensures the service provider will appropriately safeguard PHI. It ensures that any third-party email service providers comply with HIPAA regulations.
Obtaining explicit consent before sending PHI via email ensures that patients are informed about the risks of email communication and provide their authorization.
