Burn of second degree of unsp thumb (nail), init encntr

This code signifies a partial-thickness burn affecting the thumb, including the nail, where the specific thumb (left or right) is not documented. Second-degree burns are characterized by blistering, redness, and pain, indicating damage to the epidermis and superficial dermis. This particular code is used for the initial treatment of such an injury.

Apply this code when a patient presents for the first time with a second-degree burn on their thumb, and the medical record does not specify which thumb was injured. This would include scenarios like a patient accidentally touching a hot surface with their thumb, resulting in blistering, and the physician's documentation simply states "thumb burn, 2nd degree."

• Ensure the documentation clearly states "second degree" and "thumb" without laterality specified.
• Verify this is the patient's first encounter for this specific burn injury.
• If laterality (left or right thumb) is documented, a more specific code should be selected.
