Toxic effect of cyanides, intentional self-harm, init encntr

This code signifies a patient presenting with adverse health effects resulting from exposure to cyanide, where the exposure was deliberately self-inflicted. The patient is in the initial phase of treatment for this poisoning. Cyanide toxicity can manifest rapidly and severely, affecting multiple organ systems.

Apply this code for emergency department visits or initial hospital admissions for patients who have ingested or otherwise been exposed to cyanide with the intent of self-harm. This includes cases of attempted suicide by cyanide. It is used when the patient is actively being evaluated and treated for the acute effects of the poisoning.

• Always assign an additional code for the specific intent, such as Z91.51 (Personal history of self-harm).
• Do not use this code for accidental or assault-related exposures; different codes apply for those circumstances.
• Ensure documentation clearly supports the intentional self-harm aspect and the initial encounter for treatment.
