Corrosion of unspecified degree of buttock, subs encntr

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

Use this code for subsequent encounters when a patient presents for ongoing management, wound care, or evaluation of a chemical burn to the buttock, and the medical record does not specify the burn's depth. This applies to situations where the initial injury has been treated, and the patient is returning for further care.

• Ensure the documentation clearly states "corrosion" or "chemical burn" to the buttock.
• Only use this code for follow-up visits; an initial encounter would use the "A" seventh character.
• If the degree of corrosion is specified in the medical record, a more specific code should be selected.
