Revision

“Do you have any advice on coding for a return to the operating room within the 90-day postoperative global period for revision of the prior procedures that were performed? The patient had a 1st metatarsocuneiform joint (MTCJ) fusion and 2nd toe, proximal interphalangeal joint (PIPJ) fusion for a hammertoe. Post op x-rays demonstrated excellent fixation and alignment. The patient returned 2 weeks later and had obvious abnormal clinical changes to position of the fusions. X-rays showed loss of position correction at the 1st MTCJ fusion and the 2nd toe fusion as the two-component implant had disengaged and dislocated. The patient didn’t recall any injury. This required a return to the OR for revision of the fusion of both joints done three weeks post operative. The 1st MTCJ plate and screws were removed, the joint realigned and a new plate/screw construct applied. The 2nd toe PIPJ was opened, and the two-component implant re-engaged for alignment correction. Is the following coding scenario 28740 -78, CPT 28285 -78 correct to bill?”
