Corrosion of first degree of left upper arm, init encntr

This code signifies a first-degree chemical burn, also known as a corrosion, affecting the left upper arm. A first-degree burn involves only the epidermis, presenting with redness, mild swelling, and pain, but no blistering or skin breakage. This specific code indicates the initial treatment or encounter for this injury.

Use this code when documenting a patient presenting for the first time with a superficial chemical burn to their left upper arm. This applies to injuries caused by contact with corrosive substances, resulting in epidermal damage without blistering. It is appropriate for the initial evaluation and management of such an injury.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the injury.
• Confirm the laterality (left) and body part (upper arm) are accurately documented in the medical record.
• Ensure the documentation clearly specifies "first degree" and "corrosion" to support this specific code.
