Performance of wrong procedure (op) on correct patient

This code signifies a medical error where a surgical or invasive procedure was performed on the correct patient, but the procedure itself was incorrect for that patient's condition or intended treatment. This means the patient received an operation that was not indicated or was the wrong type of intervention for their diagnosis.

This code is appropriate when a patient undergoes a procedure that was not the one planned or necessary for their specific medical need, even though the patient identity was correctly established. Examples include performing an appendectomy when a cholecystectomy was indicated, or a knee arthroscopy when a shoulder arthroscopy was planned for a different patient.

• Ensure the documentation clearly states that the procedure was incorrect, not just the side or body part.
• This code should be used as a secondary diagnosis, with the primary diagnosis reflecting the patient's actual condition or reason for the initial encounter.
• Differentiate carefully from situations where the correct procedure was performed on the wrong side or body part, as that is coded elsewhere.
