Corrosion of 3rd deg mu sites of right wrist and hand, init

This code signifies a severe, full-thickness burn (corrosion) affecting multiple areas of the right wrist and hand. The injury involves destruction of all skin layers, potentially extending into subcutaneous tissue, muscle, or bone, and typically presents with a leathery appearance and insensitivity to touch.

Apply this code for patients presenting with a third-degree chemical burn to multiple sites on their right wrist and hand during the initial phase of treatment. This includes the emergency department visit, initial hospitalization, or first outpatient encounter for this specific injury.

• Ensure documentation specifies "third degree" and "multiple sites" on the right wrist and hand.
• Confirm the encounter is the "initial encounter" for this specific injury; subsequent encounters will require a different seventh character.
• Always code the external cause of the corrosion (e.g., chemical exposure) in addition to this diagnosis code.
