Tox eff of halgn deriv of aliphatic hydrocrb, slf-hrm, init

This code signifies a patient's self-inflicted poisoning due to exposure to halogenated aliphatic hydrocarbons, excluding those specifically classified elsewhere (e.g., carbon tetrachloride, chloroform). This indicates a deliberate act of self-harm using these chemical agents, with the patient presenting for initial treatment.

Apply this code when documentation clearly states an intentional overdose or self-poisoning with an unspecified halogenated aliphatic hydrocarbon. This is appropriate for the initial visit where the acute effects of the exposure are being managed.

• Ensure documentation explicitly states "intentional self-harm" or similar language.
• Verify the specific chemical agent is not one with a more specific ICD-10-CM code.
• Always assign an additional code for the specific substance if known and not already captured.
