Corrosion of third degree of back of left hand, subs encntr

This code signifies a third-degree chemical burn (corrosion) affecting the back of the left hand. A third-degree burn involves full-thickness destruction of the skin, extending into subcutaneous tissue, and often presents with a leathery, charred, or waxy appearance.

This code is used for follow-up encounters for a patient being treated for a third-degree chemical burn on the back of their left hand. This includes visits for wound care, debridement, skin grafting, or monitoring of healing after the initial treatment has been rendered.

• Ensure the documentation specifies "corrosion" (chemical burn) and not a thermal burn.
• Verify the laterality (left hand) and specific anatomical site (back of hand) are clearly documented.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
