Clinical Context
A 34-year-old patient with a history of opioid use disorder presents to an outpatient behavioral health clinic for an initial comprehensive treatment planning visit. The patient reports recent relapse after a period of abstinence, has positive urine drug screen for opioids, and requests coordinated care for medication-assisted treatment, counseling, and social support. The clinical workflow begins with an intake interview by a licensed clinician (licensed clinical social worker or addiction counselor), review of prior treatment records, administration of screening instruments (e.g., CAGE-AID, ASI-lite), and a focused biopsychosocial assessment. The clinician documents current substance(s) of use, frequency, severity, medical comorbidities, psychiatric history, risk factors (overdose risk, pregnancy), and social determinants (housing, employment). The team develops a written individualized treatment plan outlining goals, measurable objectives, services to be delivered (medication management, individual therapy, group therapy, case management), frequency, responsible providers, anticipated duration, and criteria for modification or discharge. If clinically indicated, the plan is modified during subsequent visits for clinical deterioration, improved stability, or new comorbidities. The service is commonly billed by outpatient behavioral health agencies, community mental health centers, and certified addiction treatment programs. Typical sites of service include outpatient clinic, behavioral health center, community substance use disorder treatment program, and Federally Qualified Health Centers. This activity corresponds to the HCPCS Level II code T1007 for alcohol and/or substance abuse services involving treatment plan development and/or modification and is documented in the medical record as a time- and content-specific treatment planning encounter tied to applicable ICD-10 diagnosis codes and payor requirements.
