Cal. Health and Safety Code § 1439.53

(a) Long-term care facilities shall protect personally identifiable information regarding residents’ sexual orientation, whether a resident is transgender, a resident’s transition history, and HIV status from unauthorized disclosure, as required by the federal Health Insurance Portability and Accountability Act of 1996 (42 U.S.C. Sec. 300gg), if applicable, the Confidentiality of Medical Information Act (Part 2.6 (commencing with Section 56) of Division 1 of the Civil Code), if applicable, regulations promulgated thereunder, if applicable, and any other applicable provision of federal or state law. A facility shall take any steps reasonably necessary to minimize the likelihood of inadvertent or incidental disclosure of that information to other residents, visitors, or facility staff, except to the minimum extent necessary for facility staff to perform their duties. (b) Long-term care facility staff not directly involved in providing direct care to a resident, including, but not limited to, a transgender or gender-nonconforming resident, shall not be present during physical examination or the provision of personal care to that resident if the resident is partially or fully unclothed without the express permission of that resident, or his or her legally authorized representative or responsible party. A facility shall use doors, curtains, screens, or other effective visual barriers to provide bodily privacy for all residents, including, but not limited to, transgender or gender-nonconforming residents, whenever they are partially or fully unclothed. In addition, all residents, including, but not limited to, LGBT residents, shall be informed of and have the right to refuse to be examined, observed, or treated by any facility staff when the primary purpose is educational or informational rather than therapeutic, or for resident appraisal or reappraisal, and that refusal shall not diminish the resident’s access to care for the primary purpose of diagnosis or treatment.
