    Clinical & Coding Specifications

    Clinical Context

    A 34-year-old patient with a history of chronic opioid dependence presents to a licensed opioid treatment program for daily supervised methadone dosing. The patient was assessed at intake with diagnosis F11.20 (opioid dependence, uncomplicated) and has individualized treatment goals. On each visit, a credentialed addiction medicine clinician or certified substance use disorder counselor verifies identity, conducts a brief clinical check for signs of intoxication or withdrawal, documents medication administration, and provides ancillary counseling or referral as needed. Methadone is dispensed and administered on-site in cups or take-home doses per program policy and regulatory limits. Clinical workflow typically includes check-in, medication reconciliation, toxicology screening if indicated, nursing or medical staff directly observing ingestion, documentation of lot/dose and clinician signature, and scheduling of follow-up visits or counseling sessions. Instances of intoxication (e.g., F11.220, F11.221) prompt clinical reassessment, possible withholding of dose, and documentation of the reason for altered administration or additional interventions.
