Toxic effect of glycols, undetermined, subsequent encounter

This code signifies an adverse health effect resulting from exposure to glycols, where the intent of the exposure (e.g., accidental, intentional self-harm) cannot be determined. The patient is receiving follow-up care for the toxic effects after the initial treatment phase.

Apply this code when a patient presents for ongoing management of symptoms or complications from glycol poisoning, and the documentation does not specify whether the exposure was accidental, intentional, or assault. This is appropriate for clinic visits, follow-up hospitalizations, or rehabilitation related to the initial toxic event.

• Ensure documentation clearly states "undetermined" intent for glycol exposure.
• Confirm this is a subsequent encounter, meaning the patient is no longer in the acute phase of treatment.
• Always code the specific type of glycol if known (e.g., ethylene glycol, propylene glycol) using a more specific code if available.
