Toxic effect of cyanides, assault, subsequent encounter

This code signifies the toxic effects resulting from exposure to cyanides, specifically when the exposure was intentionally inflicted by another person with the intent to harm. It indicates that the patient is receiving follow-up care for the sequelae or complications of this initial assault.

Apply this code for patients presenting for ongoing treatment, monitoring, or management of health issues directly stemming from a cyanide poisoning that occurred as an act of assault. This includes visits for chronic organ damage, neurological deficits, or psychological sequelae after the acute phase of poisoning has passed.

• Always sequence this code after the primary diagnosis for the specific condition or injury being treated.
• Ensure documentation clearly states the poisoning was due to an assault and that the encounter is for follow-up care.
• Consider additional codes for specific symptoms, organ damage, or mental health conditions resulting from the poisoning.
