Corrosion of third degree back of unsp hand, init encntr

This code signifies a severe chemical burn affecting the full thickness of the skin and underlying tissues on the back of the hand. The injury is characterized by tissue destruction, often appearing leathery or charred, and typically involves nerve damage, resulting in little to no pain at the site. It represents the initial presentation of such an injury.

Use this code for patients presenting with a third-degree chemical burn (corrosion) on the dorsal aspect of an unspecified hand. This is appropriate for the initial assessment and treatment of the burn, such as in an emergency department or initial clinic visit. It should be assigned when the specific laterality (left or right hand) is not documented.

• Ensure documentation specifies "third degree" and "corrosion" (chemical burn) on the back of the hand.
• Verify that this is the initial encounter for treatment of this specific burn.
• If laterality (left or right hand) is documented, a more specific code should be used.
