TCAR Coverage8

TCAR Surveillance Project

Effective September 1, 2016, hospitals participating in the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI) receive CMS coverage for Transcarotid Artery Revascularization (TCAR) procedures entered into the VQI Carotid Artery Stenting module.  According to the National Coverage Determination (NCD) 20.7 for Percutaneous Transluminal Angioplasty, the TCAR Surveillance Project is an FDA-approved post approval carotid stenting study.  CMS will reimburse hospitals and physicians for symptomatic and asymptomatic patients at high risk for traditional carotid artery surgery who participate in the TCAR Surveillance Project.

The Patient Safety Organization (PSO) for the SVS has made public the CMS letter detailing the approval of the TCAR Surveillance Project. The Project Coverage Letter can now be found on the VQI website with the following link:

Under NCD 20.7, the TCAR Surveillance Project does not require the study sites to get approval from the Medicare Administrative Contractors. For billing purposes, facilities and providers will submit claims for the TCAR Surveillance Project using National Clinical Trial (NCT) identifier NCT02850588.
