Corrosion of third degree of right palm, subs encntr

This code signifies a severe chemical burn affecting the entire thickness of the skin on the patient's right palm, indicating damage to all layers of the dermis and potentially underlying tissue. The injury is characterized by a leathery, dry appearance, often with no pain due to nerve damage. This specific code is used for encounters following the initial treatment of the corrosion.

Apply this code when documenting follow-up care for a patient who previously sustained a third-degree chemical burn to their right palm. This includes subsequent visits for wound care, debridement, skin grafting, or monitoring for complications. It is appropriate for any encounter after the initial acute phase of treatment.

• Ensure the documentation clearly specifies "third degree" and "corrosion" (chemical burn) to differentiate from thermal burns.
• Verify the laterality is "right palm" and not another hand location.
• The "D" seventh character indicates a subsequent encounter, meaning care after the initial treatment. Do not use for the initial visit.
