SB 504 California Senate · 2025-2026 Regular Session

Communicable diseases: HIV reporting.

Summary
Existing law requires all health care providers and laboratories to report cases of human immunodeficiency virus (HIV) infection to the local health officer and requires the local health officer to report unduplicated HIV cases to the State Department of Public Health. Existing law requires public health records related to HIV or acquired immunodeficiency syndrome (AIDS) , containing personally identifying information, that were developed or acquired by a state or local public health agency, or an agent of that agency, to be confidential and not disclosed, except as otherwise provided by law for public health purposes or pursuant to a written authorization by the person who is the subject of the record or by their guardian or conservator. Existing law authorizes certain state or local public health officials to disclose those records to other local, state, or federal public health agencies or to medical researchers when the confidential information is necessary to carry out specified duties of the agency or researcher, including in the investigation, control, or surveillance of disease. This bill would additionally authorize a health care provider of a patient with an HIV infection that has already been reported to a local health officer as described above to disclose identifying information about the patient to a local health jurisdiction or the department if the disclosure is necessary to complete or supplement an HIV case report or for the local health jurisdiction or the department to carry out its duties in the investigation, control, or surveillance of disease, or the coordination of, linkage to, or reengagement in care for a person, as specified. The bill would make conforming changes to related provisions.

MODERATE
The September 2025 amendment to SB 504 significantly expands the bill's scope by adding a full rewrite of Health and Safety Code Section 121022 (HIV case reporting), which was previously only referenced but not amended. The most notable policy changes are: (1) shifting provider disclosure language from a prohibition-with-exception ('shall not disclose unless necessary') to permissive language ('may disclose if necessary'), (2) adding an explicit prohibition on sharing HIV identifying information with the federal government, and (3) requiring continued access to anonymous HIV testing through alternative sites.
Scope change
The bill's scope expanded to include direct amendment of Health and Safety Code Section 121022 (HIV case reporting), which governs how HIV cases are reported, what information can be shared, and protections for anonymous testing. Previously the bill only amended Sections 120962, 121025, and 121026.
SCOPE

Section 121022 of the Health and Safety Code is now directly amended by the bill. Previously the bill only referenced this section without changing it. The new amendment establishes comprehensive HIV case reporting requirements, including mandatory name-based reporting by providers and laboratories, permitted disclosure pathways, breach investigation procedures, and penalties.

REQUIREMENT

Provider disclosure of patient identifying information to public health agencies changed from prohibitive language ('shall not disclose unless the disclosure is necessary') to permissive language ('may disclose if the disclosure is necessary'). This reframes the legal obligation from a restriction with exceptions to an authorization, potentially giving providers more discretion in when to share information.

ENFORCEMENT

A new provision (Section 121022(i)) explicitly prohibits any person from disclosing HIV identifying information reported under the section to the federal government, including any agency, employee, agent, or contractor acting on behalf of the federal government, except as permitted under Section 121025(b). This is a new explicit barrier against federal data sharing.

ELIGIBILITY

A new requirement (Section 121022(e)) obligates the department and local health officers to ensure continued reasonable access to anonymous HIV testing through alternative testing sites, in consultation with HIV planning groups and affected stakeholders including representatives of persons living with HIV.

TECHNICAL

Cross-references throughout Sections 121025, 121026, and Revenue and Taxation Code Section 19548.2 were updated to reflect the reorganized subdivision numbering in Section 121022 (e.g., references changed from subdivision (f) to (h), etc.).

Gender-neutral language changes: 'his or her' was replaced with 'their' in Section 121026 and related provisions.
