The American College of Radiology (ACR) and various partner associations have submitted a letter to the U.S. Centers for Medicare and Medicaid Services (CMS) requesting confirmation of Medicare reimbursement for CT lung cancer screening at independent diagnostic testing facilities (IDTFs).
Even though CMS has approved coverage for CT lung cancer screening, numerous Medicare administrative contractors (MACs) have been denying reimbursement for the test when conducted at IDTFs.
CMS delivered a letter to the ACR in February 2018 explaining that Medicare cannot cover payment for CT lung cancer screening at IDTFs because the test includes a therapeutic activity (i.e., making smoking cessation interventions available for current smokers) that requires billing by a physician.
However, CT lung cancer screening should not be considered an intervention or therapeutic service, according to the ACR and several other groups, including the Radiology Business Management Association (RBMA), the Healthcare Business Management Association (HBMA), the Association for Quality Imaging (AQI), the Medical Imaging and Technology Alliance (MITA), and the Lung Cancer Alliance (LCA).
The groups are now urging CMS to publish a change request transmittal notice instructing all MACs on the following points regarding CT lung cancer screening:
- CT lung cancer screening is not an intervention/therapeutic service.
- The test is a preventive screening service available to Medicare beneficiaries and covered in all settings, including independent diagnostic testing facilities.
- Payment for the test should be retroactive to February 5, 2015.













![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD).

Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
