Corrosion of unsp degree of left toe(s) (nail), init encntr

This code signifies damage to the skin and/or underlying tissues of the left toe(s) due to contact with a corrosive substance, without specifying the severity of the injury. The injury could involve the toe itself or the toenail. This code is specifically for the initial treatment of such an injury.

Use this code when a patient presents for the first time with a chemical burn to their left toe(s) or toenail, and the medical documentation does not specify the depth or extent of the burn (e.g., first, second, or third degree). This is appropriate for initial evaluations and treatments following the corrosive exposure.

• Only use this code for the initial encounter for treatment of the corrosion. Subsequent encounters will require a different seventh character.
• Ensure documentation clearly indicates the left toe(s) as the affected site and that the injury is due to a corrosive agent.
• If the degree of corrosion is specified in the medical record, a more specific code should be selected.
