CT colonography screening bill reintroduced in House By AuntMinnie.com staff writers March 11, 2013 — U.S. Rep. Ralph Hall (R-TX) and co-sponsor Rep. Danny Davis (D-IL) have reintroduced HR 991, the CT Colonography Screening for Colorectal Cancer Act. The bipartisan bill aims to encourage colonography screening by providing Medicare coverage for CT colonography, also known as virtual colonoscopy, according to the authors. The Medical Imaging and Technology Alliance (MITA) issued a statement applauding the bill’s reintroduction, and said it continues to urge the U.S. Centers for Medicare and Medicaid Services (CMS) to open a national coverage decision for CT colonography.
