Clinical Context

A 67-year-old patient with multiple chronic conditions (type 2 diabetes, hypertension, and recent hospital discharge for heart failure) presents to a community pharmacy clinic for an initial, in-person medication therapy management visit. The pharmacist reviews the patient’s complete medication list, medical history, recent hospital discharge summary, laboratory results, and current symptoms. The 15-minute encounter focuses on identifying drug-drug interactions, dosage appropriateness, adherence barriers, and opportunities to simplify therapy. The pharmacist documents a patient-specific medication evaluation, provides education, reconciles medications with the discharge list, and communicates recommendations to the primary care provider. The service is billed as a single, face-to-face pharmacist encounter designated for a new patient medication evaluation under 99605 and takes place in a clinic-based or community pharmacy consultation room. The workflow includes appointment scheduling, pre-visit chart review, focused patient interview and reconciliation during the 15-minute visit, documentation in the medical record, and secure transmission of findings to the treating clinician.
