Guidance to Render Unsecured Protected Health Information Unusable, Unreadable, or Indecipherable to Unauthorized Individuals

Protected health information (PHI) is rendered unusable, unreadable, or indecipherable to unauthorized individuals if one or more of the following applies:

  1. Electronic PHI has been encrypted as specified in the HIPAA Security Rule by “the use of an algorithmic process to transform data into a form in which there is a low probability of assigning meaning without use of a confidential process or key” (45 CFR 164.304 definition of encryption) and such confidential process or key that might enable decryption has not been breached.  To avoid a breach of the confidential process or key, these decryption tools should be stored on a device or at a location separate from the data they are used to encrypt or decrypt.  The encryption processes identified below have been tested by the National Institute of Standards and Technology (NIST) and judged to meet this standard.
    • Valid encryption processes for data at rest are consistent with NIST Special Publication 800-111, Guide to Storage Encryption Technologies for End User Devices.1
    • Valid encryption processes for data in motion are those which comply, as appropriate, with NIST Special Publications 800-52, Guidelines for the Selection and Use of Transport Layer Security (TLS) Implementations; 800-77, Guide to IPsec VPNs; or 800-113, Guide to SSL VPNs, or others which are Federal Information Processing Standards (FIPS) 140-2 validated.
  2. The media on which the PHI is stored or recorded has been destroyed in one of the following ways:
    • Paper, film, or other hard copy media have been shredded or destroyed such that the PHI cannot be read or otherwise cannot be reconstructed. Redaction is specifically excluded as a means of data destruction.
    • Electronic media have been cleared, purged, or destroyed consistent with NIST Special Publication 800-88, Guidelines for Media Sanitization such that the PHI cannot be retrieved.


Move quickly to secure your systems and fix vulnerabilities that may have caused the breach. The only thing worse than a data breach is multiple data breaches. Take steps so it doesn’t happen again. Secure physical areas potentially related to the breach. Lock them and change access codes, if needed. Ask your forensics experts and law enforcement when it is reasonable to resume regular operations.Mobilize your breach response team right away to prevent additional data loss. The exact steps to take depend on the nature of the breach and the structure of your business. Assemble a team of experts to conduct a comprehensive breach response. Depending on the size and nature of your company, they may include forensics, legal, information security, information technology, operations, human resources, communications, investor relations, and management. Identify a data forensics team. Consider hiring independent forensic investigators to help you determine the source and scope ...read more

A breach is, generally, an impermissible use or disclosure under the Privacy Rule that compromises the security or privacy of the protected health information.  An impermissible use or disclosure of protected health information is presumed to be a breach unless the covered entity or business associate, as applicable, demonstrates that there is a low probability that the protected health information has been compromised based on a risk assessment of at least the following factors: The nature and extent of the protected health information involved, including the types of identifiers and the likelihood of re-identification;The unauthorized person who used the protected health information or to whom the disclosure was made;Whether the protected health information was actually acquired or viewed; andThe extent to which the risk to the protected health information has been mitigated.Covered entities and business associates, where applicable, have discretion to provide the required breach notifications following an impermissible ...read more
