Our physician attempted to perform a hip resection (CPT 27091) but had to discontinue the surgery due to the patient's blood pressure. The procedure was discontinued after a portion of it was done. We know we should bill the initial surgery with a modifier 53 but are wondering the proper way to bill the reattempt at surgery. He already did half the resection so should we send the same code out for the second surgery with modifiers 52 and 76? Any assistance is greatly appreciated.
