Poisoning by pyrazolone derivatives, accidental, init

This code signifies an accidental overdose or adverse reaction to pyrazolone derivatives, a class of medications primarily used for their analgesic and anti-inflammatory properties. The patient has inadvertently ingested or been administered an excessive or incorrect dose, leading to toxic effects. This code is specifically for the initial presentation of the poisoning.

Use this code when a patient presents to an emergency department or clinic with symptoms of poisoning due to unintentional ingestion or exposure to pyrazolone derivatives. This includes situations where a patient mistakenly takes too much of their own medication, or ingests a pyrazolone derivative intended for someone else. It is appropriate for the first visit related to this specific poisoning event.

• Ensure documentation clearly states the poisoning was accidental and identifies the substance as a pyrazolone derivative.
• Always assign an additional code for the specific pyrazolone derivative, if known, from categories T39.2X-.
• Remember to also code any associated signs and symptoms or adverse effects of the poisoning.
