Burn third degree of unsp single finger except thumb, init

This code signifies a full-thickness burn affecting any single finger, excluding the thumb, where the burn extends through all layers of the skin and potentially into underlying tissue. The burn is severe enough to cause charring, waxy white, or leathery skin, and often results in nerve damage.

Apply this code for initial encounters involving a third-degree burn to a single, non-thumb finger. This is appropriate when the specific finger involved is not documented, or when the documentation refers to an "unspecified finger."

• Ensure documentation clearly specifies a third-degree burn and involvement of only one finger, excluding the thumb.
• Verify that this is the initial encounter for treatment of the burn.
• If the specific finger (e.g., index, middle) is documented, a more specific code from the T23.32- series should be used.
