Corrosion of 3rd deg mu sites of right wrs/hnd, sequela

This code describes a severe, full-thickness skin injury (third-degree burn) on multiple sites of the right wrist and hand, specifically caused by corrosive chemicals. It indicates that the injury is a sequela, meaning it represents a late effect or complication of an initial corrosive burn that occurred in the past.

Use this code when documenting a patient presenting with a chronic or residual condition resulting from a previous third-degree corrosive burn to the right wrist and hand. This would include conditions like scar contractures, chronic pain, or functional impairment directly attributable to the past corrosive injury. Do not use for acute corrosive burns.

• Ensure the documentation clearly specifies "corrosion" as the etiology and "third degree" for the burn depth.
• Verify that the injury involves "multiple sites" of the right wrist and hand, not just a single location.
• Confirm that the encounter is for a sequela, indicating a late effect rather than the initial acute injury.
