Corrosion of unspecified degree of right palm, subs encntr

This code signifies tissue damage to the right palm caused by a corrosive substance, such as a strong acid or alkali, where the specific depth or severity of the burn is not documented. It indicates that the patient is receiving follow-up care for this injury after the initial treatment phase.

Apply this code when a patient presents for ongoing management, such as wound checks, dressing changes, or physical therapy, for a chemical burn to their right palm. This is appropriate when the initial encounter for the burn has already been coded, and the degree of corrosion was not specified in the medical record.

• Ensure the documentation clearly states "right palm" and indicates a subsequent encounter for the corrosion.
• Only use this code when the degree of corrosion (e.g., first, second, or third degree) is not specified by the provider.
• Pair with an external cause code (V00-Y99) to describe the circumstances of the injury, if known.
