Percutaneous Image-guided Lumbar Decompression for Lumbar Spinal Stenosis
PILD for LSS is a posterior decompression of the lumbar spine performed under indirect image guidance without any direct visualization of the surgical area. This is a procedure proposed as a treatment for symptomatic LSS unresponsive to conservative therapy. This procedure is generally described as a non-invasive procedure using specially designed instruments to percutaneously remove a portion of the lamina and debulk the ligamentum flavum. The procedure is performed under x-ray guidance (e.g., fluoroscopic, CT) with the assistance of contrast media to identify and monitor the compressed area via epidurogram.
On January 9, 2014, CMS issued a Medicare National Coverage Determination (NCD) which allows coverage of PILD for LSS under Coverage with Evidence Development (CED) with certain conditions. The NCD that requires a prospective, randomized, controlled clinical trial (RCT) design is available on our website at http://www.cms.gov/medicare-coverage-database/details/nca-decision-memo.aspx?NCAId=269.
On December 7, 2016, CMS expanded this NCD to allow coverage of PILD for LSS under CED in a prospective longitudinal study using an FDA-approved/cleared device that successfully completed a CMS-approved RCT with certain conditions. The NCD that requires a prospective longitudinal study design is available on our website at https://www.cms.gov/medicare-coverage-database/details/nca-decision-memo.aspx?NCAId=284.
As part of CED, we are identifying below the Medicare approved clinical trials which have been reviewed and determined to meet the requirements of coverage.
