Toxic effect of glycols, accidental (unintentional), subs

This code signifies a harmful reaction to glycol exposure that occurred unintentionally, and the patient is now presenting for follow-up care or continued treatment after the initial acute phase. Glycols are organic compounds often found in antifreeze, de-icers, and some solvents, and their toxic effects can range from gastrointestinal upset to severe metabolic acidosis and organ damage.

Use this code when a patient is seen for ongoing management of symptoms, complications, or recovery from an accidental glycol poisoning. This includes follow-up appointments, subsequent hospitalizations for related issues, or continued outpatient treatment after the initial presentation.

• Always assign a code for the specific manifestation(s) of the toxic effect in addition to this external cause code.
• Ensure the "D" seventh character is appropriate for a subsequent encounter, indicating care after the initial treatment.
• Verify the exposure was indeed accidental and not intentional (e.g., self-harm) or assault, as different codes would apply.
