Cardiac surgery
About 33267: Open left atrial appendage exclusion
Reports open surgical exclusion of the left atrial appendage as a standalone service, using a method such as suturing, stapling, or excision.
The surgeon excludes the left atrial appendage through an open approach, using the method appropriate to the operation, such as suturing, stapling, or excision. This service is used in selected patients with atrial fibrillation as part of surgical stroke-risk management. Cardiothoracic surgeons typically perform it in an operating room, either as a standalone procedure or alongside other cardiac surgery; when it accompanies another cardiac procedure, the related add-on code distinguishes that circumstance.
Select this code for open LAA exclusion performed as a standalone service, not for a thoracoscopic approach or exclusion performed during another cardiac procedure. The operative report should identify the open approach, the appendage treated, the exclusion method, and whether another cardiac procedure was performed in the same session. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in one 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 service. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33267 billing questions
When should 33267 be used instead of 33268?
Use 33267 for open LAA exclusion performed as a standalone service. Use 33268 when open LAA exclusion is performed during another cardiac procedure.
How does 33267 differ from 33269?
33267 describes an open approach. 33269 is for thoracoscopic LAA exclusion.
Can the LAA exclusion be reported with another cardiac procedure?
If open LAA exclusion is performed during another cardiac procedure, report the applicable add-on code, 33268, rather than 33267. Document the procedures and the operative approach.
What documentation supports reporting 33267?
The operative report should establish the open approach, the left atrial appendage treated, the exclusion method, and whether the service was standalone or performed during another cardiac procedure.
Can modifier 50 be reported, and can an assistant be paid?
Modifier 50 is inappropriate based on the descriptor and anatomy. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation.
