CPT® Code 90296

Equine diphtheria antitoxin is a specialized immunizing agent that provides passive immunity to individuals exposed to diphtheria. This antitoxin is derived from the blood serum of horses that have been immunized against the diphtheria toxin, allowing them to produce specific antibodies. When administered to a recipient, these antibodies circulate throughout the body and work to neutralize the harmful toxins produced by the diphtheria bacteria. The administration of this antitoxin can occur via any route, making it versatile in its application. It is important to note that this CPT® code specifically reports the use of the diphtheria antitoxin product itself, rather than the procedure or method of administration. This distinction is crucial for accurate medical coding and billing, ensuring that healthcare providers are appropriately reimbursed for the use of this vital immunizing agent.
