An adult recipient of services, parents or custodian if the recipient is a minor, or the recipient’s guardian, must be given the opportunity to refuse generally accepted behavioral health or developmental disability services, including medication, unless those services are necessary to prevent the recipient from causing serious harm to the recipient or to others. If services are refused, the recipient, guardian, or parent or custodian of a minor must be informed of alternate services available, the risks of those alternate services, and the possible consequences to the recipient of the refusal of generally accepted services.
