Implement policies and procedures for authorizing access to ePHI

Access to ePHI must be granted based on the minimum necessary standard: workforce members should access only the ePHI they need to perform their job functions. This requires formal procedures for authorizing access, establishing the access each role is permitted, and modifying or removing access when roles change. Proper information access management prevents both accidental exposure and intentional misuse of ePHI by limiting the blast radius of any one account being compromised or misused.

Implementation steps

  1. 1

    Define access authorization procedures

    Establish written procedures for who can authorize access to ePHI systems, what information is required to request access, and what criteria must be met. Access should require both a business need and management approval. Define roles or job functions with standard access packages to simplify provisioning while enforcing least privilege.

  2. 2

    Establish and document access levels by role

    Document which ePHI systems and data each role can access and at what permission level (read, write, delete, admin). Use role-based access control so permissions are tied to job functions rather than individuals. Review and update the role definitions when job functions change.

  3. 3

    Implement access modification procedures

    Define procedures for modifying access when a workforce member changes roles. A promotion, department transfer, or job function change may require granting new access and revoking old access. Establish a process so that role changes trigger an access review rather than simply adding new permissions on top of existing ones.
