Tox eff of unsp halgn deriv of aromat hydrocrb,slf-hrm, sqla

This code signifies a long-term health problem or complication resulting from a deliberate act of self-poisoning with an unspecified halogenated hydrocarbon. The initial acute toxic event has resolved, but the patient continues to experience residual effects.

Use this code when documenting a patient presenting with a chronic condition or sequela directly attributable to a past intentional self-harm attempt involving an unknown halogenated hydrocarbon. This applies to follow-up encounters where the lasting impact of the poisoning is being addressed.

• Requires a seventh character "S" to indicate sequela, meaning the residual effect of a past injury or disease.
• Ensure documentation clearly links the current condition to the previous intentional self-harm and the specific substance class.
• Do not use for acute poisoning events; those would require an initial encounter (A) or subsequent encounter (D) seventh character.
