Policy overview & scope

Policy provides payment, coding, and documentation guidance for short-term 24-hour behavioral health services including acute residential treatment, crisis stabilization units, inpatient detoxification, and observation beds. The policy references the American Society of Addiction Medicine (ASAM) levels of care to inform appropriate placement in the continuum of services for substance use disorder and co-occurring mental health conditions.

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.
