Poisoning by opth drugs and prep, undetermined, sequela

This code signifies a long-term consequence or residual effect resulting from an unconfirmed or unknown cause of poisoning by medications specifically used for eye conditions. It indicates that the acute poisoning event has passed, but the patient continues to experience health problems directly attributable to that past exposure.

Use this code when documenting a patient presenting with a chronic condition or permanent injury that is a direct result of a previous poisoning by an ophthalmological drug, and the intent (accidental, intentional self-harm, assault) of the original poisoning cannot be determined. This applies to situations where the initial poisoning event is no longer active, but its lasting impact is being treated.

• Always sequence this code after the code(s) for the specific sequela (e.g., blindness, corneal scarring).
• Ensure documentation clearly links the current condition to a past ophthalmological drug poisoning.
• Only use "undetermined" when there is insufficient information to classify the intent of the poisoning.
