Ohio Revised Code Title XXI. Courts Probate Juvenile § 2135.04

(A) A declaration becomes operative when both of the following apply:

(B) A mental health treatment provider for a declarant or a health care facility providing services to a declarant shall make a declaration part of the declarant's medical record and shall note in that record when the declaration is operative.

(C) A mental health treatment provider for a declarant or a health care facility providing services to a declarant shall act in accordance with an operative declaration of the declarant consistent with reasonable medical practice, the availability of treatments requested, and applicable law. The mental health treatment provider or the health care facility shall continue to act in accordance with an operative declaration until the declarant has the capacity to consent to mental health treatment decisions.

(D) An operative declaration of a declarant supersedes any general consent to treatment form signed by the declarant prior to, upon, or after the declarant's admission to a health care facility to the extent there is a conflict between the declaration and the form, even if the declarant signs the form after the execution of the declaration. To the extent that the provisions of a declarant's declaration and a general consent to treatment form signed by the declarant do not conflict, both documents shall govern the use or continuation, or the withholding or withdrawal, of mental health treatment for the declarant. This division does not apply if a declarant revokes a declaration after the declarant signs a general consent to treatment form.
