(c) A person determined and certified to be:

(1) An outpatient; and

(2) A person for whom there is available outpatient treatment

shall be considered to be in need of involuntary outpatient treatment and not involuntary inpatient treatment for purposes of further proceedings under this article until such time as that person's status is determined to be otherwise pursuant to those proceedings.

(d) A person determined and certified to be a mentally ill person requiring involuntary treatment who does not meet all of the requirements of paragraphs (1) and (2) of subsection (c) of this Code section shall be considered to be in need of involuntary inpatient treatment and not involuntary outpatient treatment for purposes of further proceedings under this article until such time as that person's status is determined to be otherwise pursuant to those proceedings.
