    Clinical & Coding Specifications

    Clinical Context

    A typical patient scenario involves an adult enrolled in an outpatient alcohol or substance use disorder treatment program who requires supervised child care while attending counseling, medication management, group therapy, or methadone/buprenorphine dosing visits. For example, a 34-year-old mother with opioid use disorder attends a two-hour individual counseling session at a community behavioral health center. The center provides on-site child sitting services for her 4-year-old during the visit so she can fully participate in treatment. Intake staff verify the child’s emergency contact information, immunization status, and any special needs. A trained childcare worker documents arrival and departure times, supervision activities, behavioral incidents, and any health concerns. Billing staff link the child sitting service to the parent/guardian’s substance abuse treatment encounter and submit HCPCS Level II code T1009 on the professional claim with the primary substance use disorder diagnosis code on the parent’s record. Typical clinical workflow steps: intake verification and consent for child care; child handoff to childcare staff; ongoing supervision and documentation; child handback and parental acknowledgement; coding and claim submission referencing the parent’s treatment encounter and T1009 for the child supervision service.
