Corros 2nd deg mul left fingers (nail), not inc thumb, init

This code signifies a second-degree chemical burn affecting multiple fingers on the left hand, excluding the thumb. The injury specifically involves the nail or nail bed area of these fingers, indicating damage beyond the superficial epidermal layer.

Apply this code when documenting a patient presenting with a chemical burn to the left hand, where multiple fingers (not the thumb) show blistering, partial-thickness skin loss, or damage to the nail structure. This is appropriate for the initial treatment or evaluation of such an injury.

• Ensure the documentation specifies "left" hand and "multiple fingers" (excluding the thumb) to justify this code.
• Verify the burn is explicitly described as "second degree" or "partial thickness" and caused by a corrosive substance.
• Confirm this is the patient's initial encounter for this specific injury; subsequent encounters will require different seventh characters.
