Toxic effect of fusel oil, intentional self-harm, sequela

This code signifies a long-term health problem or complication arising from a deliberate act of self-poisoning with fusel oil. It indicates that the patient is experiencing residual effects from a past intentional ingestion of this toxic substance.

Apply this code when documenting chronic conditions, disabilities, or other lasting sequelae directly attributable to a prior intentional fusel oil overdose. This would be used in follow-up encounters after the acute phase of the poisoning has resolved, but the patient continues to suffer from its consequences.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., liver damage, neurological impairment).
• Ensure documentation clearly links the current condition to a past intentional fusel oil exposure.
• Do not use this code for acute poisoning; use the appropriate acute poisoning code with the "A" or "D" seventh character for initial or subsequent encounters.
