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

This code signifies a severe chemical burn affecting the full thickness of the skin and underlying tissues on the posterior aspect of the patient's right hand. It indicates that the patient is receiving follow-up care for this injury after the initial treatment phase.

Apply this code when documenting subsequent encounters for a patient being treated for a third-degree chemical burn to the back of their right hand. This includes visits for wound care, debridement, skin grafting, or monitoring for complications after the initial acute phase.

• Ensure documentation specifies "third degree" and "back of right hand" for accurate code assignment.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for initial treatment of the injury; a different seventh character would be required.
