Toxic effect of glycols, undetermined, initial encounter

This code signifies an adverse health effect resulting from exposure to glycols, such as ethylene glycol or propylene glycol, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined from the available documentation. This represents the initial phase of treatment for such an event.

Apply this code when a patient presents with signs and symptoms of glycol toxicity, and the medical record clearly indicates that the circumstances surrounding the exposure are unknown or unspecifiable. This is appropriate for the first encounter for this specific poisoning event.

• Always sequence this code first when documenting the toxic effect, followed by codes for specific manifestations of the toxicity.
• Ensure documentation explicitly states "undetermined" or "unknown intent" regarding the glycol exposure.
• Do not use this code if the intent (e.g., accidental, intentional) is clearly documented; instead, use the appropriate intent-specific code.
