Corrosion of second degree of abdominal wall, sequela

This code signifies a second-degree corrosion (chemical burn) affecting the abdominal wall, where the acute injury has healed, but the patient is still experiencing residual effects or complications from the original burn. These sequelae might include scarring, contractures, chronic pain, or functional limitations directly attributable to the past corrosion.

Use this code when documenting a patient encounter for the long-term management or evaluation of complications arising from a previously sustained second-degree chemical burn to the abdominal wall. This applies when the initial burn has resolved, but its lasting impact requires ongoing medical attention.

• Always use an external cause code (V00-Y99) to identify the circumstances of the corrosion, if known and applicable.
• Do not use this code for acute or active second-degree corrosions; refer to the appropriate acute T21.2- codes.
• Consider additional codes for specific sequelae, such as scar contractures (e.g., L90.5) or chronic pain (e.g., G89.29), to provide a comprehensive clinical picture.
