What 43773 covers
A bariatric surgeon performs this laparoscopically to remove and replace an adjustable gastric restrictive device component. It is used when a component has failed or been damaged and the operative plan is an exchange, rather than a revision that leaves the component in place or removal without replacement. The service is typically performed in a hospital or ambulatory surgery center. The operative report should identify the indication, the component removed, the replacement performed, and any relevant findings such as device damage.
Report this code for the laparoscopic component exchange, not for placement of a new device or removal alone. CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this procedure. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

43773 billing questions
How is this different from code 43771?
Use 43773 when a component is removed and replaced. Code 43771 describes revision of a component without that removal-and-replacement exchange.
Can this be reported when the band is only removed?
No. When the laparoscopic service removes a component without replacing it, compare code 43772. Code 43774 describes removal of the adjustable device and subcutaneous port components.
Should modifier 50 be appended?
No. The abdominal procedure is not bilateral, and modifier 50 is inappropriate.
What postoperative care is included?
The day-before preoperative visit and 90 days of related postoperative care are included in the 90-day global period.
How does CMS handle other procedures performed in the same session?
The highest-valued procedure is paid in full, with other procedures subject to the standard multiple-procedure reduction to 50%.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
