What 92990 covers
This code describes catheter-based balloon enlargement of a narrowed pulmonary valve. An interventional cardiologist typically advances a balloon catheter through the heart and across the valve, then inflates it to improve blood flow. A common clinical setting is treatment of pulmonary valve stenosis, including congenital stenosis, in a cardiac catheterization laboratory. The target is the valve itself, not a narrowed pulmonary artery branch.
Report the service when the pulmonary valve is treated, and document the diagnosis, targeted valve, catheter-based intervention, and procedural findings. CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. 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. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
