Corrosion of third degree of right palm, sequela

This code signifies a third-degree corrosion injury affecting the palm of the right hand, where the acute phase of the injury has resolved, and the patient is now presenting for treatment of a residual condition or complication directly resulting from the original corrosion. Third-degree corrosion involves full-thickness destruction of the skin and underlying tissues.

Use this code when documenting and billing for care related to long-term effects, complications, or sequelae of a previously sustained third-degree chemical burn to the right palm. This includes scenarios such as scar revision, contracture release, chronic pain management, or reconstructive surgery performed after the initial healing of the acute corrosion.

• Requires an additional code to identify the specific sequela (e.g., scar, contracture).
• Do not use for acute or initial encounters for the corrosion injury itself.
• Ensure documentation clearly links the current condition to the past third-degree corrosion of the right palm.
