Toxic effect of unspecified alcohol, undetermined, sequela

This code signifies a long-term or residual condition resulting from a toxic exposure to an unidentified type of alcohol, where the intent of the exposure (e.g., accidental, intentional self-harm) cannot be determined. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing persistent health issues directly attributable to that past event.

Use this code for patients presenting with chronic neurological deficits, organ damage, or other lasting health problems clearly documented as a consequence of a previous, unspecified alcohol poisoning. This is appropriate when the initial toxic event's intent was never established or is no longer determinable. It should be assigned after the acute phase of the poisoning has resolved.

• Always ensure documentation clearly links the current sequela to a past toxic effect of unspecified alcohol.
• Do not use this code for acute poisoning; it is exclusively for residual conditions.
• Requires a seventh character of 'S' for sequela, indicating a late effect.
