Section 1 — Legislative Declaration
Legislative findings and declaration

(1)(a)–(f) The general assembly finds and declares that: (a) Health-care decisions affect the most intimate, complex, and consequential aspects of human life, including physical survival, mental well-being, family stability, and personal dignity, and therefore must be grounded in compassion, clinical judgment, and individualized understanding; (b) Artificial intelligence systemsArtificial intelligence system"Artificial intelligence system" has the meaning set forth in section 6-1-1701 (2).C.R.S. § 10-16-112.7(1)(a) may offer valuable tools to support efficiency, data analysis, and administrative functions in health-care delivery; however, these systems cannot comprehend the full breadth and depth of the human experience, including trauma, culture, disability, grief, fear, hope, and the lived realities that shape patient health outcomes; (c) The state of Colorado has a compelling interest in ensuring that health care remains human-centered and that decisions involving coverage determinations, medical necessity, and access to treatment, particularly denials of care, are made by qualified human clinicians or physicians who are accountable for these decisions and can exercise professional judgment and ethical reasoning; (d) Reliance on artificial intelligence systemsArtificial intelligence system"Artificial intelligence system" has the meaning set forth in section 6-1-1701 (2).C.R.S. § 10-16-112.7(1)(a) to make or materially influence adverse health-care determinations without meaningful human oversight risks compounding inequities, embedding bias, and eroding trust between patients, providers, and health-care systems; (e) Artificial intelligence systemsArtificial intelligence system"Artificial intelligence system" has the meaning set forth in section 6-1-1701 (2).C.R.S. § 10-16-112.7(1)(a) may be used as an assistive tool in health-care delivery and administration but must not replace human judgment, human accountability, or the therapeutic relationship that is essential to safe, ethical, and effective care; and (f) Every Coloradan, regardless of income, insurance status, disability, language access needs, race, ethnicity, geography, or immigration status, deserves access to human-centered health care that recognizes their dignity, individuality, and humanity.

(2)(a)–(c) Therefore, the general assembly declares that it is essential to: (a) Regulate the use of artificial intelligence systemsArtificial intelligence system"Artificial intelligence system" has the meaning set forth in section 6-1-1701 (2).C.R.S. § 10-16-112.7(1)(a) in health care to ensure transparency, accountability, equity, and patient safety; (b) Prohibit automated systems from making adverse coverage determinations without qualified human review; and (c) Preserve the central role of licensed clinicians in decisions that affect the health, well-being, and lives of Coloradans.

Section 1 sets forth the General Assembly's findings regarding the role of AI in health care. It declares that health-care decisions must be grounded in compassion, clinical judgment, and individualized understanding, and that AI systems must not replace human judgment, accountability, or the therapeutic relationship. These are legislative findings that create no independent compliance obligations.

Section 10-16-112.7 is the bill's operative core, imposing requirements on carriers, pharmacy benefit managers, private utilization review organizations, behavioral health administrative services organizations, and managed care entities that use AI systems for utilization review. The section establishes multiple overlapping obligations: AI systems must base determinations on individual patient clinical data (not solely group data), must not discriminate, must be fairly and equitably applied, must produce and retain compliance documentation, must be periodically reviewed for accuracy, and must not use patient health data beyond its intended purpose.

Subsection (5) is a critical gatepost: AI may assist with utilization review including expedited approvals, but any denial based in whole or in part on medical necessity must receive human review and approval by a licensed clinician competent to evaluate the specific clinical issues. Subsection (4) requires written disclosures to the applicable state regulatory body identifying AI functions, human oversight processes, and audit procedures.

Subsection (6) creates a separate prohibition: carriers may not provide coverage for psychotherapy services provided directly to an individual and conducted by an AI system, with carve-outs for billing software, EHR, video platforms, and other nontherapeutic software tools incident to services provided by a human provider.

Section 25.5-1-209 extends the prohibition on paying for AI-delivered psychotherapy services to payers under the Colorado Medical Assistance Act (Medicaid) and the Children's Basic Health Plan Act (CHP+). This mirrors the carrier prohibition in § 10-16-112.7(6) but applies to public health programs rather than private insurance.
