Typical costs:
For patients not covered by health insurance, herniated disc surgery can cost between $20,000 and $50,000 or more, including the surgeon's fee, anesthesiologist and facility fee. A minimally invasive outpatient microdiscectomy would typically fall on the lower end, while an inpatient open discectomy with a hospital stay would fall on the higher end.
Herniated disc surgery typically is covered by health insurance if ordered by a doctor. According to eSpine.com[1] , the website of a Los Angeles-based surgeon, most insurance plans will cover spinal surgery. Medicare generally covers herniated disc surgery.
For patients covered by insurance, assuming the deductible has been met, typical out-of-pocket costs would consist of coinsurance of between 10 and 40 percent of the procedure, for a total of $2,000 or more, up to the yearly out-of-pocket maximum.
