Poisoning by natural blood and blood products

This diagnosis code signifies an adverse reaction or toxic effect resulting from the administration or ingestion of natural blood or blood components. This includes conditions such as transfusion reactions, allergic responses to blood products, or other systemic toxicities directly attributable to these substances. It indicates a harmful effect, not an intended therapeutic outcome.

Use this code when documentation clearly indicates a patient experienced poisoning or an adverse effect from natural blood or blood products, such as whole blood, packed red blood cells, plasma, or platelets. This applies to situations like acute hemolytic transfusion reactions, anaphylactic reactions to blood, or other documented toxicities. Supporting documentation should detail the blood product administered and the resulting adverse event.

• Always sequence this code as a secondary diagnosis following the code for the specific manifestation of the poisoning (e.g., anaphylactic shock, acute renal failure).
• Distinguish from complications of medical care not involving poisoning, such as mechanical complications of transfusion.
• Ensure documentation specifies "natural" blood products; synthetic or artificial blood substitutes would be coded differently.
