About 33916: Pulmonary artery embolectomy with circulatory arrest
Reports surgical removal of pulmonary artery thromboemboli using cardiopulmonary bypass with hypothermia and circulatory arrest, commonly for chronic thromboembolic obstruction.
This operation removes obstructive thromboembolic material from the pulmonary arteries while the patient is supported with cardiopulmonary bypass, hypothermia, and circulatory arrest. Cardiothoracic surgeons commonly perform it for chronic thromboembolic pulmonary hypertension, where organized material obstructs pulmonary blood flow and requires an extensive pulmonary artery endarterectomy. The service is generally performed in a hospital operating room, not an office setting.
Select this code when the operative record supports pulmonary artery embolectomy with bypass, hypothermia, and circulatory arrest; distinguish it from pulmonary artery embolectomy performed without those features. Document the treated arteries, obstructing material, operative technique, and use of bypass, hypothermia, and circulatory arrest. Medicare 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 others at 50%. Modifier 50 is inappropriate. An assistant may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

Both codes describe pulmonary artery embolectomy with cardiopulmonary bypass. Choose this code when the operative documentation also supports hypothermia and circulatory arrest.
No office rate
Code 33917 describes pulmonary artery repair, rather than removal of thromboembolic material. The operative objective and documented procedure distinguish repair from embolectomy.

33916 billing questions
How does this differ from 33915?
This code is for pulmonary artery embolectomy with cardiopulmonary bypass, hypothermia, and circulatory arrest. Use 33915 when the documented procedure does not include the hypothermia-and-arrest features that distinguish this service.
How does this differ from 33910?
Code 33910 describes pulmonary artery embolectomy without cardiopulmonary bypass. This code requires bypass with hypothermia and circulatory arrest.
Is modifier 50 appropriate?
No. CMS identifies bilateral adjustment as inappropriate for this code, so do not use modifier 50 to report work on both pulmonary arteries.
What postoperative care is included?
The 90-day 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.
What documentation supports selecting this code?
The operative report should describe pulmonary artery thromboembolic material and the embolectomy, and document cardiopulmonary bypass, hypothermia, and circulatory arrest.
