Toxic eff of halgn deriv of aromatic hydrocrb, slf-hrm, init

This code signifies a poisoning or adverse reaction resulting from the deliberate ingestion, exposure, or administration of various halogenated aromatic hydrocarbons (excluding those specified elsewhere, such as PCBs or DDT). The patient intentionally caused this toxic effect, often in an attempt to harm themselves.

Apply this code when documentation clearly indicates a patient's self-inflicted poisoning by substances like certain industrial solvents, pesticides, or other chemical compounds that fall under the "other halogen derivatives of aromatic hydrocarbons" category. This is for the initial treatment of such an event, typically in an emergency department or during the first hospitalization.

• Always sequence this code first, followed by codes for any associated physical or mental health conditions.
• Ensure documentation specifies "intentional self-harm" and identifies the substance as a halogen derivative of an aromatic hydrocarbon.
• Do not use for accidental exposures or therapeutic misadventures; those require different intent codes.
