    Clinical & Coding Specifications

    Clinical Context

    A typical patient is a 34-year-old adult with a diagnosis of moderate major depressive disorder stabilized on a selective serotonin reuptake inhibitor (SSRI). The patient presents for a brief office visit solely to monitor medication response and adjust dose due to emerging insomnia and mild anxiety. The visit is limited to prescription management: review of current medications, assessment of side effects and adherence, brief symptom check (sleep, mood, anxiety), documentation of decision to increase the SSRI dose by 25 mg, and arrangement for a follow-up telehealth or in-person medication check in two weeks. No psychotherapy, extended counseling, or comprehensive physical exam is performed during this visit. Typical workflow: patient schedules medication monitoring visit; nurse or medical assistant updates medication list and vitals as required by clinic policy; clinician conducts a focused, time-limited medication review and documents rationale for change and informed consent for dose adjustment; prescription is sent to pharmacy; visit is coded using M0064 and any applicable modifiers are appended when required by payer rules.
