Corrosion of second degree of right upper arm, init encntr

This code signifies a second-degree chemical burn, also known as a corrosion, affecting the upper arm on the patient's right side. This type of injury involves damage to the epidermis and dermis, characterized by blistering, redness, and significant pain, but typically without full-thickness skin destruction.

Apply this code when documenting a chemical burn that has resulted in partial-thickness skin damage to the right upper arm. This is appropriate for the initial assessment and treatment of such an injury, indicating the first time the patient is receiving care for this specific burn.

• Ensure the documentation clearly specifies a chemical burn (corrosion) rather than a thermal burn.
• Verify the burn degree is explicitly stated as "second degree" and the location is the "right upper arm."
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
