Poisoning by pyrazolone derivatives, assault, subs encntr

This code signifies an adverse health effect resulting from the intentional administration of a pyrazolone derivative, such as metamizole or propyphenazone, by another person with the intent to harm. The patient is receiving follow-up care for the sequelae of this poisoning, which could include organ damage, metabolic disturbances, or other complications.

This code is appropriate for documenting subsequent encounters for a patient who was poisoned by a pyrazolone derivative as a result of an assault. This includes visits for ongoing treatment, monitoring of long-term effects, or rehabilitation related to the initial poisoning event. It should be used after the initial acute phase of treatment.

• Always assign an additional code for the specific manifestation(s) of the poisoning.
• Ensure documentation clearly supports the "assault" intent and "subsequent encounter" for accurate code assignment.
• Do not use this code for accidental poisonings, self-harm, or poisonings of undetermined intent.
