Corros second degree of single r finger except thumb, init

This diagnosis code indicates a second-degree chemical burn affecting a single finger on the right hand, excluding the thumb. The injury specifically involves the nail or the surrounding nail bed area. A second-degree burn is characterized by blistering, pain, and damage extending beyond the epidermis into the dermis.

Apply this code when documenting a patient's initial presentation for a chemical burn to a single right finger (not the thumb) where the damage is classified as second-degree and involves the nail. This would include incidents such as accidental exposure to strong acids, bases, or other corrosive substances resulting in blistering and partial-thickness skin damage to the specified digit.

• Ensure the burn is explicitly documented as a "corrosion" or "chemical burn" and not a thermal burn.
• Verify the laterality (right hand) and the specific digit involved (single finger, not the thumb).
• Confirm the burn depth is documented as "second degree" and that it is the patient's initial encounter for this specific injury.
