Poisoning by pyrazolone derivatives, assault, init encntr

This code signifies an intentional act of harm involving the administration of pyrazolone derivatives, such as certain anti-inflammatory or analgesic medications, with the intent to injure another person. The patient is experiencing the acute effects of this poisoning, requiring initial medical evaluation and treatment.

This code is appropriate when a patient presents with symptoms of pyrazolone derivative toxicity, and the medical record clearly documents that the poisoning was a result of an assault. This includes situations where the substance was forcibly administered or covertly given with malicious intent. It should be used for the initial encounter where the patient is first seen for this condition.

• Always ensure the documentation explicitly states "assault" or similar language indicating intentional harm by another party.
• Verify that the substance involved is a pyrazolone derivative; if not, a different poisoning code will be necessary.
• The "A" at the end signifies an initial encounter; subsequent encounters for treatment of this poisoning will require a different seventh character.
