Corrosion of first degree of unspecified foot, init encntr

This code signifies a superficial burn injury to an unspecified foot, characterized by redness and pain without blistering or skin breakage. It indicates damage caused by a corrosive substance, such as a strong acid or alkali, affecting only the outermost layer of the skin.

Apply this code when documenting a patient's initial presentation for a first-degree chemical burn to the foot. This is appropriate for cases where the specific foot (left or right) is not documented, and the injury is due to a corrosive agent.

• Ensure the documentation clearly states "first degree" and "corrosion" or "chemical burn."
• Only use this code for the initial treatment of the injury; subsequent encounters will require a different seventh character.
• Verify that the laterality of the foot is not specified in the medical record before using the "unspecified" digit.
