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

This code signifies a toxic reaction resulting from the deliberate ingestion or exposure to halogenated aromatic hydrocarbons, excluding those specifically classified elsewhere (e.g., PCBs, dioxins). The patient is presenting for follow-up care or management of sequelae after the initial acute phase of the self-harm event.

Use this code for patients receiving ongoing treatment, monitoring, or rehabilitation for complications arising from an intentional overdose or self-poisoning with unspecified halogenated aromatic hydrocarbons. This applies to encounters after the initial emergency room visit or acute hospitalization. Examples include follow-up appointments for organ damage, neurological deficits, or mental health support related to the self-harm attempt.

• Ensure documentation clearly states "intentional self-harm" and specifies a "subsequent encounter."
• Always code the specific substance if known and available in the ICD-10-CM tabular list.
• Concurrently code any associated mental health diagnoses (e.g., depression, suicidal ideation) and specific physical manifestations of the toxic effect.
