If a CSP stores only encrypted ePHI and does not have a decryption key, is it a HIPAA business associate?

If a CSP stores only encrypted ePHI and does not have a decryption key, is it a HIPAA business associate?

Answer:

Yes, because the CSP receives and maintains (e.g., to process and/or store) electronic protected health information (ePHI) for a covered entity or another business associate.  Lacking an encryption key for the encrypted data it receives and maintains does not exempt a CSP from business associate status and associated obligations under the HIPAA Rules.  An entity that maintains ePHI on behalf of a covered entity (or another business associate) is a business associate, even if the entity cannot actually view the ePHI.[1]  Thus, a CSP that maintains encrypted ePHI on behalf a covered entity (or another business associate) is a business associate, even if it does not hold a decryption key[i] and therefore cannot view the information.  For convenience purposes this guidance uses the term no-view services to describe the situation in which the CSP maintains encrypted ePHI on behalf of a covered entity (or another business associate) without having access to the decryption key.

While encryption protects ePHI by significantly reducing the risk of the information being viewed by unauthorized persons, such protections alone cannot adequately safeguard the confidentiality, integrity, and availability of ePHI as required by the Security Rule.  Encryption does not maintain the integrity and availability of the ePHI, such as ensuring that the information is not corrupted by malware, or ensuring through contingency planning that the data remains available to authorized persons even during emergency or disaster situations.  Further, encryption does not address other safeguards that are also important to maintaining confidentiality, such as administrative safeguards to analyze risks to the ePHI or physical safeguards for systems and servers that may house the ePHI.

As a business associate, a CSP providing no-view services is not exempt from any otherwise applicable requirements of the HIPAA Rules.  However, the requirements of the Rules are flexible and scalable to take into account the no-view nature of the services provided by the CSP.

Direct Liability of Business Associates In 2009, Congress enacted the Health Information Technology for Economic and Clinical Health (HITECH) Act,1  making business associates of covered entities directly liable for compliance with certain requirements of the HIPAA Rules.

Entity Rescinds Improper Charges for Medical Record Copies to Reflect Reasonable, Cost-Based Fees Covered Entity: Private Practice Issue: Access A patient alleged that a covered entity failed to provide him access to his medical records.  After OCR notified the entity of the allegation, the entity released the complainant’s medical records but also billed him $100.00 for a “records review fee” as well as an administrative fee.  The Privacy Rule permits the imposition of a reasonable cost-based fee that includes only the cost of copying and postage and preparing an explanation or summary if agreed to by the individual.  To ...read more
