The median cost of a CT scan without insurance is generally $695 for a brain CT, $785 for a chest CT and $900 for an abdomen CT, according to NerdWallet in October 2014. Those costs are for scans without contrast and may be a little lower than those with contrast.
Location can play a huge role in the cost of a CT scan, says NerdWallet. A brain CT in Lanham, Maryland, was only $75, while Maryland also had a $100 chest CT and a $120 abdomen CT. The most expensive CTs were in Washington, D.C., California and Washington state. Insurance policies could cover part or all of the cost if the companies find that the CTs are necessary.
