Corrosion of third degree of unspecified palm, subs encntr

This code signifies a severe, full-thickness injury to the palm of the hand caused by a corrosive substance, such as a strong acid or alkali. The damage extends through all layers of the skin, potentially involving underlying tissues, and the specific palm (left or right) is not documented. This particular code indicates that the patient is receiving follow-up care for this injury after the initial treatment.

Apply this code when a patient presents for subsequent treatment, such as wound care, debridement, skin grafting, or infection management, for a third-degree chemical burn to an unspecified palm. This is appropriate for any encounter following the initial acute care phase of the injury.

• Ensure documentation clearly states "corrosion" or "chemical burn" and specifies "third degree" or "full thickness" to justify this code.
• The "D" seventh character indicates a subsequent encounter; verify that this is not the initial treatment for the injury.
• If the specific palm (left or right) is documented, a more specific code should be used. Query the provider if clarification is needed.
