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

This code signifies a superficial chemical burn (corrosion) affecting the back of the right hand, characterized by redness and pain without blistering or skin loss. It indicates that the patient is receiving follow-up care for an injury that has already been initially treated.

Apply this code when documenting subsequent visits for a patient whose first-degree chemical burn on the dorsal aspect of their right hand is being re-evaluated, dressed, or monitored for healing. This includes scenarios where the patient returns for routine wound checks or minor adjustments to their care plan after the initial encounter.

• Ensure the documentation clearly specifies "first degree" and "back of right hand" to support this precise code.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine follow-up care for the injury.
• Verify the etiology is corrosion (chemical burn) rather than a thermal burn, as different code categories apply.
