In simple words: This code indicates long-term health problems that developed after accidentally being poisoned by a pyrazolone derivative medication.

Poisoning by pyrazolone derivatives, accidental (unintentional), sequela. This code represents the late effects or residual conditions resulting from accidental poisoning by pyrazolone derivatives.

Example 1: A patient experiences long-term kidney damage following an accidental overdose of metamizole, a pyrazolone derivative., A patient develops chronic gastrointestinal issues as a sequela of unintentional phenazone poisoning., A patient has persistent neurological symptoms following accidental exposure to a pyrazolone derivative-containing product.

Documentation should include details of the initial poisoning event, the specific pyrazolone derivative involved, and the nature of the sequelae. Supporting clinical findings and diagnostic test results confirming the long-term effects are essential. Any treatment received for the poisoning and subsequent sequelae should also be documented.

** Pyrazolone derivatives are a group of medications with analgesic and antipyretic properties. Examples include metamizole, phenazone, and propyphenazone. These drugs are commonly used to treat pain and fever. However, they can cause adverse effects, especially when taken in large doses or for extended periods.
