Can dental imaging be shared through text messaging?

Can dental imaging be shared through text messaging?

HIPAA mandates strict guidelines to protect patients' sensitive medical information, including dental imaging. Text messaging can lack the security measures to safeguard protected health information (PHI). Sharing dental imaging through text messaging is not recommended for HIPAA compliance. 



In the context of dental practices, PHI encompasses all patient-specific information, including dental imaging, used for diagnosis and treatment planning. This means that dental professionals are bound by HIPAA regulations to safeguard the privacy and confidentiality of dental imaging, just as they would with any other PHI.


The HIPAA privacy rule and dental imaging

The HIPAA privacy rule governs the use and disclosure of PHI, aiming to balance protecting patients' privacy and allowing necessary information sharing for treatment purposes. Under this rule, dental practices must obtain patient consent and provide proper disclosures when handling dental imaging.

Obtaining written consent from patients allows dental practitioners to use and disclose dental imaging for treatment, payment, and healthcare operations. Patients must be informed about the specific purposes for which their dental imaging will be used and to whom it may be disclosed. This transparency helps patients make informed decisions and promotes trust between patients and their dental providers.


Challenges with text messaging and dental imaging

  • Interception and unauthorized access: Text messaging is inherently vulnerable to interception, making it unsuitable for transmitting PHI without appropriate safeguards. Unauthorized access could compromise patient privacy.
  • Misdirected sharing: Auto-complete features and saved messages may lead to misdirected sharing of dental imaging, raising privacy concerns.
  • Mobile device risks: Text messages are stored on mobile devices, which can be lost or stolen, potentially exposing sensitive patient data to unauthorized parties.
  • Lack of audit trail: HIPAA requires covered entities to maintain an audit trail of all PHI disclosures. Regular text messaging lacks robust audit trail capabilities, making it difficult for dental practices to track and document the sharing of dental imaging adequately. Without an audit trail, it becomes challenging to demonstrate compliance with HIPAA regulations in the event of an audit or investigation.
  • Limited control over data retention: Many text messaging applications retain messages on devices or servers for an extended period. Dental practices have limited control over the retention and deletion of messages, raising concerns about the secure disposal of PHI when it is no longer needed. This poses challenges in adhering to HIPAA's requirements for data retention and disposal.
  • Potential for insecure backups: Some mobile devices automatically back up messages to cloud services. If not adequately secured, these backups may expose dental imaging and other PHI to unauthorized access from cloud providers or hackers.


Recommended HIPAA compliant methods for sharing dental imaging

  1. HIPAA compliant messaging apps: Secure messaging apps that meet HIPAA standards offer encryption, multi-factor authentication, and secure data storage. These apps are designed explicitly for healthcare professionals to exchange PHI securely. Dental practitioners can use these apps to share dental imaging with colleagues, specialists, or patients while maintaining privacy and compliance.
  2. Encrypted email services: Dental practices can use HIPAA compliant email services to send dental imaging securely. 
  3. Secure file-sharing platforms: Specialized platforms designed for sharing medical data securely provide encryption and access controls. They allow dental practitioners to share dental imaging with authorized parties securely.
