CPT code 36440 designates a rapid blood transfusion for patients two years old or younger administered via injection device or syringe. Nationally, this code captures a specialized, time-sensitive pediatric procedure typically performed in neonatal or pediatric inpatient settings. It matters for billing and clinical documentation because it distinguishes a rapid, single-instance transfusion technique for infants from standard, slower transfusion methods used in older children and adults.

Readers will find an overview of clinical context for neonatal and infant transfusion, common billing considerations tied to this CPT code, and typical sites of service where the procedure is delivered. Benchmarks, payer coverage patterns, and any relevant policy updates or coding guidance that impact reimbursement and documentation practices are summarized.

The publication provides concise guidance on what the code represents, the clinical scenarios where it is used, and the practical billing elements that organizations and coders should track.
