A cardiac stent procedure ranges in price from $11,000 to $41,000 without insurance, as of 2015, according to CostHelper Health. If insurance covers the procedure, a patient can expect to pay a 10 to 20 percent co-pay. The cost depends on the type of stent and length of hospital stay.
A cardiac stent is a small, metal tube that supports weakened coronary arteries. A balloon catheter is used to insert the stent into the artery. The balloon is removed, but the stent remains permanently to keep the artery open. In some cases, a surgeon may used a stent coated in medicine to decrease the chance of re-blockage of the artery, explains WebMD.
