↵a A full clinic visit is a conventional facility visit that provides the services that were typical of a predifferentiation visit, generally including a consultation with a clinician, counseling, laboratory tests if scheduled, and a medication refill.
↵b Other interactions include any interaction with a provider that has been tailored for the population served, including off-site medication pickups, adherence club participation, or a clinical consultation adjusted for the population in question, including specialist consultations for certain types of patients (i.e., all interactions except conventional, undifferentiated full clinic visits).
↵c Includes models for known unsuppressed patients, high viral load clinics, pediatric clinics, and models that accept both stable and nonstable patients.
