What 33822 covers
A patent ductus arteriosus is a persistent connection between the aorta and pulmonary artery. This code describes surgical repair by dividing that connection in a patient younger than 18. A congenital cardiothoracic surgeon typically performs the operation in a hospital operating room, commonly through a left thoracotomy. The operative report should establish the patient’s age and document division of the ductus, rather than ligation alone.
Report this code for the division approach in a patient under 18; age and operative technique distinguish it from the adult division code and the ligation code. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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% reduction. Modifier 50 is inappropriate because the anatomy is not bilateral. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33822 billing questions
How does this code differ from PDA ligation?
Use this code when the surgeon divides the ductus as part of the repair. The ligation code, 33820, describes repair by ligation.
Does the patient’s age determine whether this or 33824 applies?
Yes. This code is for division repair in a patient younger than 18; 33824 is the corresponding division code for a patient 18 or older.
Can modifier 50 be reported?
No. The PDA is a single connection, and CMS identifies bilateral adjustment as inappropriate for this service.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
May an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.
