Preventive visits are strictly age-dependent, and using the wrong CPT code can result in immediate denials or downcoding. Pediatric and adolescent well visits must align with the patient’s exact age at the time of service and whether they are new or established.
Codes 99381–99385 apply to new patients, while 99391–99395 are reserved for established patients — and even a small mismatch can trigger payer scrutiny.
