What 33910 covers

This service involves surgically removing obstructing embolic material from the pulmonary artery while the patient is supported by cardiopulmonary bypass. A cardiothoracic surgeon typically performs it in an operating room for a serious pulmonary embolism when operative embolectomy is selected. The work centers on clearing the pulmonary artery; it is distinct from treating chronic pulmonary artery obstruction through a percutaneous revascularization approach.

Report this code when the operative record supports pulmonary artery embolectomy performed with cardiopulmonary bypass. Documentation should identify the embolic disease, the operative removal, and use of bypass. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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% multiple-procedure reduction. Modifier 50 is inappropriate for this service. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

33915Pulmonary embolectomy
Choose 33910 when the pulmonary artery embolectomy is performed with cardiopulmonary bypass. Code 33915 is for the procedure without bypass.
33900Pulmonary artery treatment
33900 describes percutaneous pulmonary artery revascularization, not open removal of embolic material with cardiopulmonary bypass.
33917Pulmonary artery repair
33917 concerns pulmonary artery repair. Use 33910 for embolic material removal with bypass, rather than repair of the artery.

33910 billing questions

How is 33910 distinguished from 33915?

33910 is for pulmonary artery embolectomy performed with cardiopulmonary bypass. 33915 describes the corresponding embolectomy without bypass.

What documentation supports reporting 33910?

The operative report should establish removal of embolic material from the pulmonary artery and use of cardiopulmonary bypass. It should also describe the operative service performed.

Does the 90-day global period include postoperative care?

Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

Should modifier 50 be appended for emboli in both pulmonary arteries?

No. Modifier 50 is inappropriate for this service; report the procedure without treating it as a bilateral service.

How are other procedures in the same session paid?

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