There are several ways that PHI is protected under HIPAA in neonatal care: 1. Access Controls: Only authorized personnel can access neonatal health information. 2. Encryption: PHI is encrypted to protect information that is stored electronically. 3. Audit Controls: Systems are in place to track access to neonatal health records. 4. Physical Safeguards: Measures such as locked file cabinets and restricted access areas are used to protect paper records.
