C.R.S. § 25.5-5-309

(1) The health-care practitioner for each pregnant woman who is enrolled or eligible for services pursuant to section 25.5-5-101 (1)(c) or 25.5-5-201 (1)(m.5) is encouraged to identify as soon as possible after the woman is determined to be pregnant whether the woman is at risk of a poor birth outcome due to substance use during the prenatal period and in need of special assistance in order to reduce the risk. If the health-care practitioner makes such determination regarding any pregnant woman, the health-care practitioner is encouraged to refer the woman to any entity approved and licensed by the behavioral health administration in the department of human services for the performance of a needs assessment. Any county department of human or social services may refer an eligible woman for a needs assessment, or any pregnant woman who is eligible for services pursuant to section 25.5-5-201 (1)(m.5) may refer herself for a needs assessment. (2) For the purposes of this section, unless the context otherwise requires, a “needs assessment” means an assessment that is designed to determine the services that are needed for a pregnant woman to minimize the occurrence of a poor birth outcome due to substance use by the pregnant woman.
