Dilate L Subclav Vn w Cel Impermabl Dev , Perc, New Tech 11

This code describes a procedure to widen a narrowed left subclavian vein using a specialized device that prevents cell growth into the vessel lumen. This intervention is performed through a percutaneous approach, meaning it is done via a puncture through the skin rather than an open incision. The "New Technology Group 11" designation indicates the use of a novel device or technique.

This code is appropriate for inpatient encounters where a patient undergoes percutaneous angioplasty of the left subclavian vein to treat stenosis, and a cell-impermeable intraluminal device is deployed. This procedure is often performed to improve blood flow, address symptoms of upper extremity venous obstruction, or facilitate access for hemodialysis.

• Verify that the documentation explicitly states the use of a "cell impermeable" device and specifies the left subclavian vein.
• Confirm the approach was percutaneous; an open approach would necessitate a different character.
• Ensure the documentation supports the "New Technology Group 11" designation for the specific device used.
