Additional Info

• Use this code for anaphylaxis of any severity --- INCLUDING anaphylactic shock.
• Also, code the also code substance, if known. This list contains the available substances.

• • There are several groups of codes that can be used to identify the substance:
    • Drug or biological substance/agent NOS used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Antibiotic/anti-infective drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Insulin or antidiabetic drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Hormone/hormone agonist drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Antineoplastic drug (chemotherapy) used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Immunosuppressive drug used appropriately, adverse effect (reaction, allergy, hypersensitivity) Thrombolytic drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)]]
    • Opioid/narcotic drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Aspirin or salicylate or nonsteroidal antiinflammatory drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Acetaminophen used appropriately (tylenol, paracematol), adverse effect (reaction, allergy, hypersensitivity)
    • Antiseizure drug NOS, used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Benzodiazepine drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Sedative drug NOS used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Anesthetic gas used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Tricyclic antidepressant drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Antidepressant drug NOS used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Psychotropic/psychiatric drug NOS, used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Cardiac drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Neuromuscular blocking drug used appropriately, adverse effect (reaction, allergy, hypersensitivity)
    • Drug NOS used appropriately, adverse effect (reaction, allergy, hypersensitivity)
