    Clinical & Coding Specifications

    Clinical Context

    A typical patient is a 45-year-old with chronic noncancer pain who is receiving long-term opioid therapy and presents for a routine follow-up visit. The treating clinician — commonly a primary care physician, pain medicine specialist, or addiction medicine clinician — reviews the patient’s opioid management plan, discusses risks and benefits, documents informed consent, and obtains the patient’s signed opioid treatment agreement (opioid pain contract) during the visit. The signed agreement is scanned or entered into the electronic health record and referenced in the progress note. The workflow includes verification of current medication list, assessment of pain control and function, evaluation for aberrant drug-related behaviors, review of urine drug testing results if applicable, and updating the treatment agreement at least once while opioids are being prescribed. Typical site of service is an outpatient clinic (office visit) or ambulatory pain center. The service documents that a signed opioid treatment agreement exists at least once during ongoing opioid therapy, supporting monitoring, care coordination, and compliance activities.
