Healthcare Data Breach Response
HIPAA-compliant breach response guide. Healthcare breaches cost $10.93 million on average—highest of any industry. Know your notification obligations and penalty exposure.
HIPAA Breach Notification Requirements
The HIPAA Breach Notification Rule (45 CFR §§ 164.400-414) requires covered entities and business associates to notify affected individuals, HHS, and potentially media following a breach of unsecured Protected Health Information (PHI).
What Constitutes a HIPAA Breach?
A breach is the acquisition, access, use, or disclosure of PHI in a manner not permitted under the Privacy Rule which compromises the security or privacy of the PHI.
Exception: An acquisition, access, use, or disclosure of PHI that does not include the identifiers listed at 45 CFR §164.514(e)(2), date of birth, and zip code does not compromise the security or privacy of the PHI.
Required 4-Factor Risk Assessment
Before notification, conduct this assessment to determine if breach notification is required. All four factors must be considered:
- 1 Nature and extent of PHI involved
Types of identifiers and likelihood of re-identification. Direct identifiers (SSN, DOB) increase risk.
- 2 Unauthorized person who received/accessed PHI
Was it a covered entity, business associate, or unknown third party? Higher risk if external.
- 3 Whether PHI was actually acquired or viewed
Access opportunity vs. confirmed access. Forensic evidence of data exfiltration?
- 4 Extent to which risk has been mitigated
Assurances from recipient, data destruction confirmation, encryption status.
HIPAA Notification Timelines
Breach Affecting 500+ Individuals
- • Individual notification: Within 60 days of discovery
- • HHS notification: Within 60 days of discovery (immediate if possible)
- • Media notification: Within 60 days if 500+ in single state/jurisdiction
Breach Affecting Fewer Than 500 Individuals
- • Individual notification: Within 60 days of discovery
- • HHS notification: Within 60 days of end of calendar year
- • Media notification: Not required
Discovery Date: The first day the breach is known, or reasonably should have been known, to the covered entity. Not the date when investigation is completed.
HHS/OCR Breach Reporting Portal
File breach reports electronically via the HHS breach portal: ocrportal.hhs.gov
Required Information:
- • Covered entity name and contact information
- • Business associate information (if applicable)
- • Breach discovery date and date range of breach
- • Number of individuals affected
- • Type of PHI involved (demographic, financial, clinical, etc.)
- • Location of breached information (laptop, network server, email, etc.)
- • Type of breach (theft, loss, unauthorized access, improper disposal, etc.)
- • Safeguards in place before breach
- • Actions taken in response
HIPAA Penalty Structure
| Tier | Culpability Level | Per Violation | Annual Max |
|---|---|---|---|
| Tier 1 | Did not know (and could not have known) | $100 - $50,000 | $1,500,000 |
| Tier 2 | Reasonable cause (not willful neglect) | $1,000 - $50,000 | $1,500,000 |
| Tier 3 | Willful neglect (corrected within 30 days) | $10,000 - $50,000 | $1,500,000 |
| Tier 4 | Willful neglect (not corrected) | $50,000 | $1,500,000 |
Note: Each affected individual can constitute a separate violation. A breach affecting 10,000 individuals with willful neglect could theoretically result in $500 million in penalties (10,000 × $50,000). OCR has discretion but the exposure is significant.
