Corrosion of unspecified degree of left foot, init encntr

This code signifies a chemical burn, or corrosion, affecting the left foot, where the specific depth or severity of the burn is not documented. It indicates the very first time a patient is receiving treatment for this particular injury.

Apply this code when documentation clearly states a chemical burn to the left foot, but the physician has not specified whether it's a first, second, or third-degree injury. This is appropriate for the initial visit or active treatment phase for the corrosion.

• Requires a seventh character "A" for initial encounter, indicating active treatment.
• Ensure the documentation explicitly mentions the left foot as the affected site.
• If the degree of corrosion is specified (e.g., first, second, or third degree), a more specific T25.4- code should be used.
