Corrosion of first degree of abdominal wall, sequela

This code indicates a first-degree corrosion (chemical burn) affecting the abdominal wall, specifically documenting a long-term complication or residual effect of the original injury. This means the initial chemical burn has healed, but there are lasting consequences.

Use this code when documenting a patient presenting with a current condition that is a direct result of a past first-degree chemical burn to the abdominal wall. This applies to follow-up encounters for scar tissue, pigmentation changes, or other chronic issues stemming from the original corrosion.

• Requires a seventh character "S" for sequela, indicating a late effect.
• Do not use for acute chemical burns; those require an "A" (initial encounter) or "D" (subsequent encounter) seventh character.
• Always code the nature of the sequela (e.g., scar, dermatitis) first, followed by this code to identify the cause.
