- The operation is controversial, with critics calling it 'expensive, dangerous and ineffective'.
What is a spinal fusion?
Spinal fusion is surgery which permanently connects two or more vertebrae in your spine, thereby stopping motion between them and reducing pain. During the operation, your surgeon places bone (or a bone-like material) between the space in the two spinal vertebrae. Metal plates are often used to hold the vertebrae together, so they can heal as one solid structure. Spinal fusion surgery usually takes between 3 and 7 hours, using general anaesthetic the whole time. The typical hospital stay is between 2 and 7 days.
You might need spinal fusion for:
- Spinal weaknesses. Your spine can become weak and unstable as a result of conditions such as severe arthritis in the spine or specific injuries.
- Herniated disk. After the removal of a herniated disk, you might need a spinal fusion.
- Spinal deformities. Spinal fusion is often used to treat spinal deformities such as scoliosis.
Must read: Possible dangers of spinal fusion
We're not doctors, but you should know that spinal fusions are controversial. Critics say there's little high-quality evidence supporting the procedure for most back issues. Critics claim the treatment is expensive, often ineffective and that most back problems can be treated with less costly procedures. There is a lot of disagreement on this point, and the Medicare benefit for spinal fusions was almost amended in 2019 as a result. Be sure to do your own research before you make any major decisions.
Does Medicare cover spinal fusion?
In the public system, Medicare will cover the cost of medically necessary spinal surgery. You can find spinal surgery items within sub-group 17 (spinal surgery) of group T8 (surgical operations) on the Medicare Benefits Schedule (MBS). Item numbers 51011 to 51171 cover various spinal surgery operations, including spinal fusions. Costs vary depending on the surgery and surgeon but for a rough guide, item number 51013 has a fee of $2,430.55.
In a private hospital, Medicare will also cover 75% of the MBS fee, with you and your private health care provider paying the rest. Fees in the private sector tend to be significantly higher than the public system, however.
How does private health insurance cover spinal fusion?
You should be able to find cover for spinal fusion with all silver tier hospital policies under back, neck and spine. Most policies come with a 2-month waiting period, or 12-months if you have relevant pre-existing conditions.
Hospital treatment with private health insurance for back, neck and spine usually covers the investigation and treatment of the back, neck and spinal column, including spinal fusion. This includes sciatica, prolapsed or herniated disc, spinal disc replacement and spine curvature disorders such as scoliosis, kyphosis and lordosis.

Finder Score - Hospital cover health insurance
Each month we analyse our hospital insurance products and rate each one on price and features. What we end up with is a nice round number out of 10 that helps you compare hospital cover a bit faster.
Before we start scoring, we need to make sure we're comparing like-for-like. Just as it doesn't make sense to compare a bicycle with a Ferrari, it doesn't make sense to compare basic hospital policies to top-tier Gold policies. Each policy is given a price score and feature score. These are then combined to determine each policies's Finder Score.
How much does spinal fusion surgery cost?
Spinal fusion in the private system without insurance costs from $25,000 to $58,000+. Surgeon's fees tend to be the main expense (from $14k to $35k+) but costs like hospital admission and anaesthetists also contribute. Here are some of the estimates we were able to find:
| Source | Cost | Notes |
|---|---|---|
| Medibank | $42,226 | Medibank's cost estimation comes from claims data from partner hospitals. It doesn't include additional out-patient costs. |
| HCF | $24,219 - $48,458 | HCF's cost estimate varies based on a range of gap options and whether a partner hospital is used. |
Out-of-pocket costs for spinal fusion
Before you agree to any complex procedure, make sure your health provider will cover you. Ask them about potential out-of-pocket expenses, such as consultation and anaesthesia fees. Be sure to ask for the MBS item number from the surgeon as well. That way, you'll have a good idea of any out-of-pocket expenses.
If you choose to go private, it's likely your health fund will have a No Gap scheme. Always ask the surgeon you use if they are participating in the scheme; this will keep out-of-pocket expenses to a minimum. Doctors' fees can vary significantly so it's smart to ask them about their fees before commencing treatment.
Because spinal fusion is a complex procedure, you may encounter out-of-pocket costs for an orthopaedic surgeon, specialist consultations, assistant surgeon, anaesthetist, pathologist and radiologist. Ask your health insurance provider about costs for these services before surgery.
