Corrosion of unspecified degree of neck, initial encounter

This code signifies a burn-like injury to the neck caused by a chemical substance, where the specific depth or severity of the tissue damage (e.g., first, second, or third degree) is not documented. It indicates an acute injury requiring initial medical attention.

Use this code when a patient presents with a chemical burn to the neck and the medical record does not specify the degree of corrosion. This is appropriate for the initial visit for treatment of the acute injury.

• Ensure the documentation clearly states "corrosion" or "chemical burn" to the neck.
• Only use this code when the degree of the burn is explicitly unspecified in the medical record.
• Append additional external cause codes (e.g., X-codes) to describe the circumstances of the injury.
