Cardiothoracic surgery

About 33820: Patent ductus arteriosus ligation

Reports surgical closure of a patent ductus arteriosus by ligation, rather than division, during an operative repair.

A cardiothoracic surgeon uses this code when surgically closing a patent ductus arteriosus by ligating the vessel. The procedure is generally performed in an operating room for a patient with a persistent connection between the aorta and pulmonary artery; the operative report should identify the ductus and describe the ligation performed. The code distinguishes ligation from repair methods that divide the ductus.

Select the code from the documented operative technique, not simply from the diagnosis of PDA or the patient’s age. The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is not appropriate for this ductus repair. Assistant-at-surgery services may be paid; co-surgeon and team-surgery reporting are not permitted for this service.

33820 billing questions

How does this code differ from 33822 or 33824?

This code is for ligation of the ductus. Codes 33822 and 33824 describe division-based PDA repair, with the age distinction reflected in those codes.

What documentation supports reporting the ligation code?

The operative report should identify the patent ductus arteriosus and document that the surgeon closed it by ligation. A PDA diagnosis alone does not establish the operative method.

Can an assistant surgeon be reported?

Assistant-at-surgery services may be paid for this procedure. CMS does not permit co-surgeon or team-surgery reporting for it.

How does the 90-day global period affect postoperative care?

The global period includes the day-before preoperative visit and related postoperative care for 90 days after the operation.

Can modifier 50 be used?

No. Modifier 50 is not appropriate for this ductus repair.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
