Cardiothoracic surgery
About 33824: Adult patent ductus arteriosus division and repair
Surgical division and closure of a patent ductus arteriosus in a patient age 18 or older, reported for operative repair of this persistent vascular connection.
A patent ductus arteriosus is a persistent connection between the aorta and pulmonary artery. This code describes surgical division of the ductus and closure of the divided ends in an adult. A cardiothoracic surgeon typically performs the operation in an operating room, often through a thoracic surgical approach, when the ductus is being treated with open repair rather than ligation alone.
Report this code for patients age 18 or older when the operative documentation supports division and repair; age and the documented technique distinguish it from the pediatric division code and the ligation code. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures 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 inappropriate for this single ductus. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33824 billing questions
How is this code distinguished from 33820?
33824 describes division and repair of the ductus in a patient age 18 or older. 33820 describes PDA repair by ligation, so the documented operative technique matters.
When should 33822 be reported instead?
33822 is the division-and-repair code for patients younger than 18. Use 33824 for patients age 18 or older when the operative report supports division and repair.
Does the 90-day global period include routine postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used for PDA repair?
No. The code concerns repair of a single ductus, so modifier 50 is inappropriate.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
