HIPAA Integrity 45 CFR 164.312(c)
The Integrity standard requires policies and procedures to protect ePHI from improper alteration or destruction. Electronic mechanisms must corroborate that ePHI has not been altered or destroyed in an unauthorized manner.
What the regulation requires
One addressable implementation specification sits under this standard: the mechanism to authenticate ePHI. In modern environments that means hashing, digital signatures, immutable logs, and EHR-level integrity controls.
Implementation specifications
Mechanism to Authenticate ePHI
Implement electronic mechanisms to corroborate that electronic protected health information has not been altered or destroyed in an unauthorized manner. (164.312(c)(2))
How Petronella implements this safeguard
Every Petronella HIPAA engagement maps 45 CFR 164.312(c)(1) to documented evidence in your environment. This is what that looks like in practice for the hipaa integrity standard:
- EHR integrity controls with audit-trail enforcement preventing chart modification without attribution.
- Cryptographic hashing on backup archives so corruption or tampering is immediately detectable.
- Immutable logging in the SIEM (write-once storage) so audit history cannot be altered post-incident.
- Digital signatures on signed clinical documents and BAAs for non-repudiation.
Built on top of ComplianceArmor for documentation, training records, and BAA inventory, with optional HIPAA managed IT services for the technical safeguard layer and vCISO services for the named Security Official role.
Where most practices fall short
OCR resolution agreements, HHS audit reports, and our own engagements show the same handful of gaps under 45 CFR 164.312(c)(1). We surface these before they become a finding.
- Backup archives are not hashed or signed, so post-ransomware integrity cannot be proven.
- EHR allows late chart edits without audit-trail entries (an EHR misconfiguration that voids the integrity safeguard).
- Clinical document workflow accepts edits to signed notes without warning or version control.
- Cloud storage uses default "versioning off," leaving no integrity baseline if ransomware encrypts current copies.
