Althea Smart EHR’s AI Billing Assistant automatically selects the correct age-range preventive visit CPT code (99381–99385 for new patients, 99391–99395 for established patients) at every well-child encounter. It also captures vaccine administration codes (90460, 90461 with counseling units), developmental screening add-on codes (96110), and applies Modifier -25 automatically when a sick problem is addressed at the same visit as a well-child exam, a frequently missed revenue opportunity in pediatric practices.
