Does an email subject line have to be HIPAA compliant?

Does an email subject line have to be HIPAA compliant?

HIPAA regulations ensure that healthcare organizations safeguard patients' protected health information (PHI). While HIPAA does not explicitly address email subject lines, the best practices should be examined to ensure HIPAA compliant email communication. 


Understanding HIPAA and email communication

HIPAA was established to safeguard the privacy, security, and integrity of patients'  protected health information (PHI). It applies to covered entities such as healthcare providers, health plans, and healthcare clearinghouses. Email is a convenient communication channel in the healthcare industry, prompting the need to understand the implications of email communication within the scope of HIPAA regulations.


Evaluating email subject lines under HIPAA

While HIPAA does not explicitly mention email subject lines, they can still pose risks to patient privacy if not handled carefully. Email subject lines are often visible even before the email is opened, making it imperative to avoid disclosing sensitive information. Including specific medical details or identifiable information in subject lines could expose PHI to unauthorized individuals.


Best practices for HIPAA compliant email subject lines

To remain HIPAA compliant, it is recommended to adhere to the following best practices when crafting email subject lines:

  1. Use generic and non-descriptive subject lines: Subject lines should be generic and non-descriptive to avoid revealing sensitive medical information. For example, instead of "Regarding your recent lab results," a more HIPAA compliant subject line could be "Follow-up on recent appointment."
  2. Avoid specific medical details: Do not include specific medical details, diagnoses, or treatment information in the subject line. The subject line should be a high-level summary that does not disclose any patient-specific information.
  3. Convey the purpose without revealing PHI: The subject line should communicate the general purpose of the email without revealing any PHI. For instance, "Appointment reminder for next week" or "Insurance coverage inquiry" convey the purpose without disclosing sensitive details.
  4. Encrypt the email content: While the subject lines may not be encrypted, it is essential to encrypt the email content if necessary. Encryption ensures that the message remains secure and protected from unauthorized access. 

Note: A secure email service, like Paubox, will encrypt the subject line, making it possible to send PHI without the risk of violating HIPAA guidelines.


HIPAA compliance in email communication

While email subject lines are an important aspect of HIPAA compliance, it is equally important to consider the broader measures for maintaining HIPAA compliance in email communication. Organizations should:

  1. Use secure, HIPAA compliant email platforms: Utilize email platforms that provide appropriate security measures, such as secure socket layer (SSL) encryption or Transport Layer Security (TLS) protocols.
  2. Implement authentication and access controls: Require strong passwords, implement two-factor authentication, and establish access controls to restrict unauthorized access to patient information.
  3. Train staff on HIPAA policies and procedures: Ensure that all staff members receive comprehensive training on HIPAA regulations, email best practices, and the proper handling of PHI.


While HIPAA does not explicitly address email subject lines, adhering to best practices allows healthcare professionals to maintain HIPAA compliance and protect patient privacy in email communication. By using generic and non-descriptive subject lines, avoiding specific medical details, and ensuring proper encryption, healthcare organizations can reduce the risk of unauthorized disclosure of PHI.
