Poisoning by oth anti-cmn-cold drugs, undetermined, sequela

This code signifies a long-term health condition or complication arising from a past poisoning event involving over-the-counter medications used to treat common cold symptoms. The specific substance involved in the original poisoning was not definitively identified at the time of the acute event, and the intent of the poisoning (accidental, intentional self-harm, assault) remains unknown.

Apply this code when documenting a patient presenting with a chronic sequela, such as organ damage, neurological deficits, or persistent functional impairment, that is directly attributable to a prior poisoning by an unspecified common cold remedy. This code is appropriate when the original poisoning occurred in the past, and the patient is now being treated for its lasting effects, with the intent of the original poisoning being undetermined.

• Always ensure documentation clearly links the current sequela to a past poisoning event.
• Confirm that the specific common cold drug was not identified and the intent of the poisoning was undetermined.
• This "S" (sequela) character indicates that the code is for the late effects of the poisoning, not the acute event itself.
