C.R.S. § 27-81-109

(1) A person with a substance use disorder, including a minor, may apply for voluntary treatment directly to an approved treatment facility. (2) Subject to rules adopted by the commissioner, the administrator in charge of an approved treatment facility shall determine who is admitted for treatment. If a person is refused admission to an approved treatment facility, the administrator may refer the person to another approved and appropriate treatment facility for treatment if it is deemed likely to be beneficial. A person must not be referred for further treatment if it is determined that further treatment is not likely to bring about significant improvement in the person’s condition, or treatment is no longer appropriate, or further treatment is unlikely to be beneficial. (3) If a patient receiving residential care leaves an approved treatment facility, the person is encouraged to consent to outpatient treatment or supportive services, if appropriate.
