What 92987 covers
An interventional cardiologist uses a catheter-delivered balloon to widen a narrowed mitral valve, typically to treat mitral stenosis. The catheter is advanced through vascular access, and the balloon is positioned across the valve and inflated to improve its opening. The procedure is generally performed in a cardiac catheterization laboratory rather than through open valve surgery.
Report 92987 for percutaneous balloon treatment of the mitral valve; balloon procedures on the aortic or pulmonary valve use different codes. The procedure report should identify the mitral stenosis, the percutaneous balloon approach, and the work and findings documented during treatment. 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 multiple-procedure reduction. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

92987 billing questions
How does 92987 differ from 92986 and 92990?
92987 is for balloon dilation of the mitral valve. The sibling codes 92986 and 92990 describe balloon procedures on the aortic and pulmonary valves, respectively.
Is modifier 50 appropriate for this procedure?
No. CMS identifies bilateral adjustment as inappropriate for 92987 because the descriptor and valve anatomy do not support bilateral reporting.
What documentation supports 92987?
The procedure report should support mitral stenosis, catheter-based balloon treatment of the mitral valve, and the procedural work and findings.
How does the 90-day global period affect related care?
The global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures in the same session paid?
For multiple procedures performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction.
When is assistant-at-surgery payment allowed?
CMS allows assistant-at-surgery payment only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
