Minor may consent
Informed consent to health care on behalf of a minor patient may be given by a member of one of the following classes, in the following order of priority: the minor's appointed guardian or legal custodian; a person authorized by the court to consent for a minor in out-of-home placement; the minor's parents; a person to whom the parent has given signed authorization; and a competent adult relative who provides a declaration under penalty of perjury.
What this means operationally
An ordered list, like Florida's and unlike Texas's, and it is the list the behavioral health chapter points back to whenever it says 'a person who may consent on behalf of the minor pursuant to RCW 7.70.065'. The entry a practice is most likely to meet without recognizing is the fourth: a parent's signed authorization transfers consent authority to whoever holds it, so the relevant question is not the adult's relationship to the child but whether they are carrying that document.
Applies when
- A person other than the minor is consenting to the minor's health care
