Corrosion of third degree of abdominal wall, sequela

This code signifies a deep chemical burn affecting the full thickness of the abdominal wall, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication directly resulting from that past corrosion. This could include issues like scarring, contractures, chronic pain, or functional impairment.

Apply this code when documenting a patient encounter for a long-term consequence or late effect of a third-degree chemical burn to the abdominal wall. This is appropriate when the initial burn has resolved, and the current treatment addresses a sequela, not the acute injury itself. Examples include surgical revision of scar tissue or management of chronic pain stemming from the original corrosion.

• Ensure the documentation clearly links the current condition to a past third-degree chemical burn of the abdominal wall.
• Always use the appropriate seventh character "S" for sequela, indicating a complication or late effect of the original injury.
• Code any specific sequela (e.g., hypertrophic scar, contracture) in addition to this code to fully describe the patient's condition.
