Corros second degree of unsp mult fngr, not inc thumb, subs

This code signifies a second-degree chemical burn affecting multiple fingers, excluding the thumb, specifically involving the nail or nail bed. A second-degree corrosion indicates damage extending beyond the epidermis, causing blistering, pain, and potential partial-thickness skin loss.

Use this code for follow-up encounters where a patient is receiving ongoing treatment for a chemical burn to the nails of multiple fingers (not the thumb). This would include scenarios such as dressing changes, wound care, or monitoring for healing or complications during the recovery phase.

• Ensure the documentation specifies "corrosion" (chemical burn) and not a thermal burn.
• Confirm the burn is to multiple fingers, excluding the thumb, and involves the nail.
• The "D" seventh character indicates a subsequent encounter for ongoing care.
