Summary & Overview
CPT 36456: Volume Replacement with Blood, Plasma, or Crystalloid
CPT code 36456 describes physician- or qualified professional-administered volume replacement by injection of donor blood, donor plasma, or crystalloid solution to replace blood loss during surgery or to restore or maintain circulating volume in a newborn infant. Nationally, this code captures a critical acute-care intervention used in operative blood management and neonatal resuscitation or stabilization, with implications for perioperative coding, transfusion services, and neonatal care billing.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for use of 36456, the typical sites of service where it is billed, and the service type. The publication also provides benchmark-oriented content, common modifiers in use, and discussion of policy and coding considerations that affect coverage and payment for acute volume replacement services. The material is intended to support coding accuracy, payer communication, and administrative decision-making in hospitals and neonatal units. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 36456 describes the administration of volume replacement in a newborn infant or during surgery by injection of donor blood, donor plasma, or a crystalloid solution in an amount equal to the blood lost or calculated to restore or maintain circulating volume. The procedure must be performed by a physician or other qualified healthcare professional.
-
Service type: Volume replacement therapy via injection (blood, plasma, or crystalloid) to restore or maintain blood volume
-
Typical site of service: Operating room or neonatal care setting (including neonatal intensive care unit and delivery suite)

Clinical & Coding Specifications
Clinical Context
A newborn infant delivered preterm at 30 weeks develops symptomatic hypovolemia in the neonatal intensive care unit after blood sampling and clinical signs of poor perfusion. The neonatologist assesses vital signs, point-of-care hemoglobin, and estimated blood volume loss. A decision is made to restore circulating volume by injecting donor blood or plasma equal to the calculated deficit. The procedure is performed by a physician or other qualified healthcare professional in the NICU or operating room under sterile conditions, with intravascular access established via an umbilical venous catheter or central venous line. Continuous monitoring of heart rate, oxygenation, and hemodynamics occurs during and after the transfusion; documentation includes indication, calculated volume, donor product type, start and stop times, patient response, and any immediate adverse events. Typical workflow includes order verification, blood product compatibility check, bedside administration by nursing under physician direction, and completion of transfusion records and billing for 36456 with appropriate modifiers and diagnosis linkage.
