Perform of correct procedure (op) on wrong side or body part

This code signifies a medical error where a surgical or invasive procedure was performed correctly, but on the incorrect anatomical side (e.g., left instead of right) or the wrong body part altogether (e.g., knee instead of hip). It indicates a deviation from the intended surgical plan regarding the location of the intervention.

This code is appropriate for documenting sentinel events such as operating on the left kidney when the right kidney was indicated, or performing a biopsy on the wrong limb. It should be used when the procedure itself was executed correctly, but the target anatomical site was erroneous.

• Always assign this code as a secondary diagnosis, as it describes a complication of medical care.
• Ensure documentation clearly specifies the intended site versus the actual site of the procedure.
• Do not use this code if the procedure itself was performed incorrectly, regardless of the site.
