Corrosion of unsp degree of unspecified thigh, subs encntr

This code signifies a chemical burn of the thigh, where the specific degree of the burn (e.g., first, second, third) is not documented. It indicates that the patient is receiving follow-up care for this injury, beyond the initial treatment.

Apply this code when a patient presents for subsequent treatment, such as wound care, dressing changes, or evaluation of healing, for a chemical burn to the thigh. This is appropriate when the initial encounter for the corrosion has already been coded and the burn degree was not specified.

• Ensure documentation clearly indicates a chemical burn (corrosion) rather than a thermal burn.
• Only use this code for subsequent encounters; an initial encounter would use the 'A' seventh character.
• Avoid using this code if the degree of the corrosion is documented; a more specific code should be selected.
