Corros 10-19% of body surface w 0% to 9% third degree corros

This code signifies a corrosive chemical burn affecting 10% to 19% of the patient's total body surface area (TBSA). Importantly, none of the affected area has progressed to a full-thickness (third-degree) burn. The injury involves superficial or partial-thickness damage from chemical exposure.

Apply this code for patients presenting with chemical burns covering 10-19% of their body, where the deepest injury is second-degree. This would include scenarios such as an industrial accident involving a caustic substance that resulted in widespread but not full-thickness skin damage. It is used when the extent of the burn is precisely measured and documented.

• Always confirm the percentage of total body surface area (TBSA) involved and the depth of the corrosion.
• Ensure documentation explicitly states that no third-degree corrosion is present within the 10-19% affected area.
• Code additional external cause codes (e.g., W20-W49 for exposure to chemicals) to fully describe the circumstances of the injury.
