Corrosion of second degree of right wrist, subs encntr

This code signifies a second-degree corrosion injury affecting the right wrist. Corrosion, in this context, refers to chemical burns that have damaged the epidermis and dermis, characterized by blistering, pain, and redness.

This code is appropriate for use on claims for follow-up care, such as wound checks, dressing changes, or medication adjustments, for a previously diagnosed second-degree chemical burn to the right wrist. It indicates that the patient is receiving ongoing treatment for the initial injury.

• Ensure documentation clearly specifies "corrosion" (chemical burn) rather than thermal burn.
• Verify the encounter is for subsequent care, not the initial treatment of the injury.
• Confirm the laterality is explicitly "right wrist" in the medical record.
