Poisoning by enzymes, assault, sequela

This code signifies a long-term or residual effect from a previous poisoning caused by enzymes, where the poisoning was intentionally inflicted by another person. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience related health issues.

Apply this code when documenting follow-up care for a patient who previously suffered an enzyme poisoning due to an assault and is now presenting with persistent symptoms or complications directly attributable to that past event. This is appropriate for chronic conditions, permanent damage, or ongoing treatment related to the initial assaultive poisoning.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current condition to a past enzyme poisoning by assault.
• Do not use for acute poisoning; this code is exclusively for sequelae.
