A Small Practice Guide to Permitted PHI Disclosures for Public Health Activities (45 CFR § 164.512(b))
Executive Summary
Small healthcare practices that manage Protected Health Information (PHI) are permitted to disclose such data without patient authorization for specific public health purposes under HIPAA Privacy Rule § 164.512(b). This article provides an in-depth guide for small practice owners and compliance officers to understand, implement, and document legally permissible disclosures to public health authorities, ensuring alignment with regulatory expectations and minimizing legal exposure.
Introduction
Small practices, defined here as those with fewer than 30 employees, often face uncertainty when navigating complex regulatory allowances under the HIPAA Privacy Rule. One critical provision, 45 CFR § 164.512(b), permits certain disclosures of PHI without patient consent, specifically for public health activities. Understanding this exception is essential, especially during outbreaks, mandatory reporting scenarios, or when coordinating with state and federal health departments.
Failing to follow these rules can result in severe penalties under HIPAA, while overly restricting disclosures can impede crucial public health interventions. This guide breaks down the regulatory language, clarifies permissible use cases, and provides actionable compliance strategies for small healthcare organizations.
Understanding § 164.512(b): Public Health Activities Exception
What does § 164.512(b) Allow?
The HIPAA Privacy Rule permits a covered entity to disclose PHI without individual authorization to public health authorities legally authorized to collect such information to prevent or control disease, injury, or disability. This includes:
- Reporting disease, injury, and vital events (e.g., births and deaths)
- Conducting public health surveillance, investigations, or interventions
- Reporting child abuse or neglect
- Reporting to employers regarding work-related illness/injury under specific conditions
Permitted Disclosures: Specific Use Cases for Small Practices
1. Disease Reporting to Public Health Authorities
Permissible Disclosure: Reporting confirmed or suspected cases of communicable diseases (e.g., COVID-19, tuberculosis, hepatitis) to state or federal agencies such as the CDC or local health departments.
Compliance Tip: Ensure that the disclosure is made only to authorized public health officials, and document the agency request or reporting mandate in your compliance log.
2. Reporting Child Abuse or Neglect
Permissible Disclosure: Disclosing PHI related to suspected child abuse or neglect to state child welfare authorities, even without patient or guardian consent.
Legal Note: These disclosures are often mandated under state law. HIPAA defers to such state-specific obligations under § 164.512(b)(1)(ii).
3. Exposure to Communicable Diseases
Permissible Disclosure: Informing individuals (e.g., caregivers or workplace contacts) about potential exposure to a communicable disease, when legally authorized to do so.
Caveat: The disclosure must be in alignment with laws authorizing public health interventions, not simply based on your professional judgment.
4. Reporting to Employers (Occupational Health Disclosures)
Permissible Disclosure: Notifying employers about work-related illnesses or injuries to comply with OSHA or similar workplace safety requirements.
Limitation: This only applies if the employer needs the information to meet legal obligations, and the employee has received written notice.
5. Disclosures for FDA-Regulated Purposes
Permissible Disclosure: Sharing PHI with persons subject to FDA jurisdiction (such as manufacturers, distributors, or researchers) for the purpose of reporting adverse events, tracking products, product recalls, post-marketing surveillance, or ensuring the safety/effectiveness of FDA-regulated products.
Example: Reporting vaccine adverse events or medical device failures to the FDA or its designees.
6. Disclosures to Schools for Proof of Immunization
Permissible Disclosure: Providing immunization records to schools that are required by state or other law to have such proof before admitting a student, provided you obtain and document the agreement of a parent, guardian, or the student (if an adult or emancipated minor).
Step-by-Step Guide to Compliant PHI Disclosures Under § 164.512(b)
Step 1: Confirm Authority of Requesting Party
- Validate that the public health authority requesting PHI is legally authorized.
- Acceptable authorities include:
- CDC
- State/local public health departments
- FDA
- OSHA (in specific contexts)
- Red Flag: Never release PHI to third-party researchers or journalists unless they meet the legal definition of a public health authority or are acting under its direction.
Step 2: Assess the Purpose of the Request
- Ensure the request aligns with one of the following:
- Disease prevention or control
- Public health surveillance
- Injury tracking
- Investigating environmental exposures
- Action Item: Document how the disclosure supports public health objectives.
Step 3: Limit the Scope of Disclosure
- Disclose only the minimum necessary information.
- Avoid full medical records unless explicitly required.
- Compliance Strategy: Create a standard form or checklist to guide staff in determining what data is essential for the request.
Step 4: Record the Disclosure
- Under 45 CFR § 164.528, most disclosures made under § 164.512(b) must be included in the patient’s accounting of disclosures (unless exceptions apply).
- Retain the documentation for at least six years.
Step 5: Train Your Team
- Conduct regular staff training on public health reporting rights and obligations.
- Emphasize when patient authorization is not required and the importance of confidentiality.
Common Pitfalls and How to Avoid Them
| Pitfall | Description | How to Avoid |
|---|---|---|
| Unauthorized Third-Party Sharing | Disclosing PHI to media, researchers, or community groups without public health authority status | Always verify the requestor’s authority and purpose |
| Excessive Disclosure | Sending entire records when only immunization data is required | Apply the "minimum necessary" standard |
| Failure to Record Disclosure | Omitting documentation in the patient’s disclosure log | Implement a compliance checklist and designate a tracking officer |
| Misinterpreting State Laws | Not accounting for stricter state privacy laws | Consult legal counsel for state-specific rules, especially around minors or mental health |
Expert Tips for Small Practices
- Designate a Disclosure Coordinator: Even in small teams, one person should oversee all public health disclosures.
- Use Templates for Common Reports: Pre-approved reporting forms reduce the risk of inappropriate sharing.
- Leverage Public Health Portals: Many state health departments provide secure online platforms for disease reporting (e.g., CDC’s National Notifiable Diseases Surveillance System (NNDSS)).
- Review Your Business Associate Agreements (BAAs): Ensure your vendors understand their disclosure limitations under HIPAA.

Real-World Case Study
Responding to a Hepatitis A Outbreak in a Small Practice Setting (a case study)
In 2023, a small urgent care clinic in the Midwest was contacted by the local Department of Health regarding a suspected Hepatitis A outbreak. Several patients who had recently visited the clinic tested positive. The clinic was asked to disclose patient contact information and immunization history to assist with contact tracing and vaccine outreach.
The compliance officer reviewed the request and determined it fell under § 164.512(b)(1)(i). The clinic disclosed only the necessary PHI patient names, contact details, visit dates, and vaccine status and recorded the disclosure in accordance with HIPAA rules. Because the disclosure was made to an authorized public health agency for an authorized purpose, patient consent was not required.
This compliant, documented action allowed for timely public health intervention and avoided regulatory scrutiny while protecting patient confidentiality.

Concluding Recommendations and Next Steps
Disclosing PHI for public health purposes under § 164.512(b) is both a legal allowance and a civic responsibility, but it must be executed with precision. Small practices should build systems for verifying authority, minimizing disclosures, training staff, and documenting each step of the process.
By doing so, you not only reduce your compliance risk but also play a vital role in protecting public health. Centralizing compliance documentation and training via integrated platforms can further strengthen your audit-readiness and reduce administrative overhead.
For those managing multiple obligations in public health, patient privacy, state laws, a proactive, centralized compliance framework is no longer a luxury but a necessity.
