Corrosion of first degree of left forearm, subs encntr

This code signifies a superficial burn injury to the left forearm, characterized by redness and pain without blistering or skin breakage. It indicates damage limited to the outermost layer of the skin (epidermis) resulting from exposure to a corrosive substance.

Apply this code when documenting a patient's follow-up visit for a first-degree corrosion of the left forearm. This includes subsequent evaluations, wound care, or monitoring of the healing process after the initial treatment.

• Ensure the documentation clearly specifies "corrosion" as the cause of the burn, not thermal or chemical.
• Verify the laterality is "left forearm" and the encounter type is "subsequent."
• Do not use for initial encounters or sequelae; specific codes exist for those situations.
