Toxic effect of trichloroethylene, self-harm, subs

This code signifies a patient presenting for follow-up care or rehabilitation after intentionally harming themselves through exposure to trichloroethylene. The initial acute toxic effects have been addressed, and the patient is now in a recovery or monitoring phase. This indicates a deliberate act of self-poisoning with this specific chemical.

Apply this code for subsequent encounters when a patient is receiving ongoing treatment, monitoring, or therapy related to a past intentional trichloroethylene poisoning. This includes visits for psychiatric evaluation, organ damage management, or rehabilitation following the initial acute care. It should be used after the initial acute phase of treatment has concluded.

• Always assign an additional code for the specific mental health condition (e.g., depression, suicidal ideation) that led to the intentional self-harm.
• Ensure documentation clearly states "subsequent encounter" and confirms the intentional nature of the trichloroethylene exposure.
• Do not use this code for the initial acute treatment of the poisoning; a code indicating an initial encounter would be appropriate for that phase.
