Technical safeguards are the technology measures that protect ePHI. Required safeguards include: access control mechanisms. unique user IDs for every person who accesses billing systems, role-based access that limits each user to the minimum necessary data, and automatic logoff after a defined period of inactivity (15 minutes is the most common standard). Encryption. all ePHI must be encrypted in transit (TLS 1.2 or higher for data transmitted over networks) and at rest (AES-256 for stored data on servers, workstations, and portable devices). Audit controls. every access to ePHI must be logged, including who accessed it, when, and what action was taken (view, edit, print, export). Logs must be retained for a minimum of six years under
HIPAA, though some states require longer. Integrity controls. mechanisms to confirm ePHI has not been altered or destroyed improperly, including checksums, version control, and backup verification. Go Medical Billing implements 256-bit AES encryption for all data at rest, TLS 1.3 for all data in transit, role-based access controls with quarterly access reviews, and thorough audit logging with six-year retention.
