Toxic effect of glycols, undetermined, sequela

This code signifies a long-term or residual health problem resulting from a past toxic exposure to glycols, where the specific type of glycol is not identified, and the intent of the exposure (e.g., accidental, intentional self-harm) is unknown. It indicates that the acute phase of the poisoning has resolved, but the patient continues to experience lasting effects attributable to the prior toxic event.

Apply this code when documenting chronic conditions or permanent disabilities directly linked to a previous, unclassified glycol poisoning. This is appropriate for patients presenting with sequelae such as renal failure, neurological deficits, or metabolic acidosis that are definitively attributed to a past toxic effect of glycols, and the initial exposure circumstances remain undetermined.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past glycol exposure and specifies the undetermined intent.
• Do not use this code for acute poisoning; instead, use the appropriate acute toxic effect code from the T52.3X category.
