Poisoning by local astringents/detergents, undet, sequela

This code signifies the long-term effects or complications arising from an exposure to local astringents or detergents, where the intent of the poisoning could not be determined. These sequelae represent residual conditions that persist after the acute phase of the poisoning has resolved. Examples might include chronic skin irritation, scarring, or other organ damage.

Use this code when documenting a patient presenting with a chronic condition directly attributable to a past, undetermined poisoning by a local astringent or detergent. This applies when the initial acute event has passed, and the current encounter is for the management of the lasting consequences. It is appropriate when the medical record clearly indicates the link between the past poisoning and the current sequela, but the intent (accidental, intentional self-harm, assault) remains unknown.

• Always sequence this sequela code first, followed by codes for the specific residual conditions.
• Ensure the documentation explicitly states the undetermined intent of the original poisoning.
• Verify that the encounter is for the management of the sequela and not the acute poisoning event.
