Corrosion of third degree of back of left hand, sequela

This code signifies a third-degree chemical burn (corrosion) that occurred on the back of the patient's left hand, and the patient is now presenting for treatment of a complication or late effect of that original injury. Third-degree burns involve full-thickness damage to the skin, including nerve endings, and often require significant medical intervention.

Use this code when documenting the long-term consequences or residual problems stemming from a past third-degree corrosion of the back of the left hand. This includes conditions like scarring, contractures, chronic pain, or functional impairment directly attributable to the original injury, after the initial acute phase of healing has passed.

• Always assign an additional code to specify the nature of the sequela (e.g., scar, contracture).
• Ensure documentation clearly indicates the injury is a "corrosion" (chemical burn) and not a thermal burn.
• Verify the laterality (left hand) and specific body site (back of hand) are accurately reflected.
