California Code, Health and Safety Code - HSC § 1599.651

A person who seeks to be admitted to the same long-term health care facility for which there exists a prior executed contract of admission which was signed by that person, or his or her legal representative, responsible party, or agent, in accordance with this chapter shall not be required to execute a new contract of admission if the person, or his or her legal representative, responsible party, or agent, either prior to or upon readmission, signs a written statement prepared by the facility which lists the modifications to the contract of admission.

The written statement shall indicate the date upon which the person's signature was obtained. The written statement shall be kept on file by the facility with the person's previously signed contract of admission.

This section shall not apply to any person who has been declared legally incompetent subsequent to the time he or she signed the contract of admission. This section shall not apply to any person when the physician and surgeon of that person has determined that the person is unable to understand and sign the written statement because of his or her medical condition.

No written statement shall contain any provision that is prohibited from being included in a contract of admission.

A new contract of admission or a written statement which lists the modifications need not be signed by the person, or his or her legal representative, responsible party, or agent, in the case of a transfer during a bedhold period.
