Poisoning by propionic acid derivatives, undet, sequela

This code signifies a long-term health condition or complication resulting from an unconfirmed or unknown intent of poisoning by propionic acid derivatives. These derivatives include common NSAIDs like ibuprofen or naproxen. The sequela could manifest as chronic organ damage, neurological deficits, or other lasting effects.

Apply this code when documentation clearly indicates a residual condition directly attributable to a past poisoning by propionic acid derivatives, and the intent of the original poisoning (e.g., accidental, intentional self-harm) could not be determined. This code is appropriate for follow-up encounters addressing the chronic effects, not the acute poisoning event itself.

• Always ensure the medical record explicitly links the current condition to a past propionic acid derivative poisoning.
• Confirm the intent of the original poisoning is documented as "undetermined" to justify this specific subcategory.
• This "S" seventh character indicates a sequela; use it for conditions that are the late effects of the poisoning.
