Corros third degree of single r finger except thumb, init

This code signifies a severe chemical burn affecting a single finger on the right hand, excluding the thumb. The corrosion has caused full-thickness tissue destruction, extending through all layers of the skin and potentially into underlying structures. The "initial encounter" indicates the patient is receiving active treatment for this specific injury.

This code is appropriate for documenting a patient presenting for the first time with a third-degree chemical burn to a single right finger (e.g., index, middle, ring, or pinky finger). It should be used when the injury is due to corrosive substances, rather than heat or electricity. This would include scenarios such as industrial chemical exposure or accidental contact with strong acids or bases.

• Ensure the documentation clearly specifies a chemical burn and not a thermal burn.
• Verify that the burn is indeed third-degree and affects only one right finger (excluding the thumb).
• Confirm this is the initial visit for this specific injury; subsequent care would require a different encounter character.
