    Clinical & Coding Specifications

    Clinical Context

    A typical patient is an adult aged 65 with multiple chronic conditions who presents for medication reconciliation during a primary care or transitional care visit. The clinician identifies a prescribed high-risk medication (for example, a benzodiazepine, long-acting opioid, or anticholinergic in an older adult) and documents that the medication was not ordered or was intentionally discontinued because risks outweigh benefits. The workflow includes: medication review in the electronic health record, assessment of risk factors (falls, cognitive impairment, renal impairment), shared decision-making documentation, an updated medication list, and communication of the change in the after-visit summary and to the dispensing pharmacy if applicable. Typical sites of service are outpatient primary care clinics, transitional care management visits, nursing facility rounds, and home health visits where medication review occurs but the high-risk medication is specifically not ordered.
