Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with opioid use disorder enrolled in an outpatient medication-assisted treatment (MAT) program who receives daily observed dosing of methadone for maintenance therapy. The patient presents to a licensed opioid treatment program or clinic where a certified dispenser or nurse documents identity verification, performs a brief clinical check (vital signs, assessment of withdrawal or sedation), and administers a measured oral dose of methadone 5 mg according to the individualized treatment plan. The workflow includes verification of the prescription/order, preparation of the correct methadone concentration, direct observation of ingestion, documentation in the medication administration record, and scheduling of the next dose or take-home dosing evaluation per program policy.
