Corrosion of unsp degree of back of right hand, init encntr

This code signifies a chemical burn of indeterminate severity affecting the posterior aspect of the patient's right hand. It indicates that the injury is due to corrosive substances, rather than thermal or electrical sources.

Apply this code when documentation specifies a chemical burn to the back of the right hand, and the degree of the burn is not yet determined or explicitly stated. This code is appropriate for the initial treatment of such an injury.

• Ensure documentation clearly states "corrosion" or "chemical burn" and specifies the "back of the right hand."
• Only use this code for the initial encounter for treatment of the injury.
• Confirm that the burn degree is unspecified; otherwise, a more specific code should be chosen.
