Clinical & Coding Specifications
Clinical Context
A 68-year-old established patient with multiple chronic conditions (type 2 diabetes mellitus, hypertension, and chronic heart failure) presents to an outpatient clinic pharmacy or ambulatory care clinic for a scheduled medication therapy management visit. The pharmacist performs a focused, face-to-face, 15-minute, patient-specific medication evaluation including review of the patient’s medical history, current medication list (prescription, OTC, and supplements), adherence barriers, recent lab values (e.g., HbA1c, renal function), and assessment for adverse drug events or drug–drug interactions. The visit includes counseling on medication use, identification of therapy optimization opportunities, and documentation of findings and recommendations in the medical record. Typical workflow: referral from primary care or chronic care management team → pre-visit chart review by pharmacist → in-person 15-minute medication evaluation using CPT 99606 → documentation and communication of recommendations to the ordering clinician and care team. Typical site of service: outpatient clinic, ambulatory care pharmacy within a medical practice, or a federally qualified health center where pharmacists provide direct patient care.
