As of 2015, the average cost of spinal fusion surgery for a person with no insurance ranges from $80,000 to $150,000 or more, according to CostHelper. The patient is likely to incur higher-end costs when the surgeon uses titanium implants.
In addition to the hospital, surgeon and anesthesia costs, spinal fusion patients may require a back brace and a walker following surgery, which can cost several hundred dollars, explains CostHelper. Patients also typically require physical therapy, which can add $1,000 or more to the costs. Doctors are likely to prescribe pain medication to ease the patient's discomfort following surgery, the cost of which varies depending on the medication.
