Toxic effect of tetrachloroethylene, self-harm, init

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion, inhalation, or other exposure to tetrachloroethylene, with the intent to harm themselves. The toxic effects can range from neurological symptoms to organ damage, depending on the dose and route of exposure.

Apply this code when documenting a patient's initial presentation for medical care following an intentional overdose or self-poisoning attempt involving tetrachloroethylene. This includes emergency department visits, initial inpatient admissions, or first outpatient encounters for such an event.

• Ensure documentation clearly states "intentional self-harm" or similar language to support the intent.
• This "A" seventh character indicates an initial encounter for treatment of the toxic effect, not necessarily the first time the patient has engaged in self-harm.
• Always code any associated physical injuries or mental health diagnoses separately.
