Billing for the administration of blood components

Hello everyone.  I am working on the billing for a new LIS and I would like to know what others are doing.  Do you charge CPT 36430 for all transfusions (adult and neonate) or do you use CPT 36430 for non-neonatal transfusions and CPT 36440/CPT 36450 for neonatal transfusions?

36430 – Transfusion, blood or blood components

36440 – Push transfusion, blood 2 years and under

36450 – Exchange transfusion, blood, newborn
