Corrosion of third degree of right wrist, sequela

This code signifies a deep tissue injury to the right wrist, specifically a third-degree corrosion, where the damage extends through all layers of the skin and potentially into underlying tissues. The "S" suffix indicates that this code is used for the late effects or complications of the initial corrosion, meaning the acute injury has healed but residual problems persist.

This code is appropriate when documenting a patient presenting with a chronic scar, contracture, functional impairment, or other long-term sequelae resulting from a previously sustained third-degree chemical burn or corrosion to their right wrist. It should be used after the initial healing phase of the acute injury has concluded.

• Always ensure documentation clearly specifies "right wrist" and "third degree" corrosion.
• The "S" suffix mandates that this code is for residual conditions, not the initial acute injury.
• Code any associated functional impairments or complications (e.g., contracture, chronic pain) in addition to this sequela code.
