Poisoning by digestants, undetermined, sequela

This code indicates a long-term health problem or complication that arose from a past poisoning event involving digestants, such as antacids, laxatives, or enzymes. The original intent of the poisoning (accidental, intentional self-harm, assault, or therapeutic error) could not be determined at the time of the initial event. The sequela represents the residual effects or chronic conditions resulting from that undetermined poisoning.

Use this code when documenting a patient presenting with a current, chronic condition directly attributable to a past poisoning by digestants, where the intent of the original poisoning was never established. This applies to follow-up encounters for persistent organ damage, neurological deficits, or other lasting health issues caused by the prior exposure.

• Always sequence the code for the specific sequela (e.g., chronic gastritis, esophageal stricture) first, followed by this sequela code.
• Ensure documentation clearly links the current condition to a past poisoning by digestants and explicitly states the undetermined intent.
• Do not use for acute poisoning events; this code is exclusively for the late effects or complications.
