Indiana Hospital Prices and Spine Surgery: What the Data Actually Shows

Why a spine surgeon is writing about hospital prices

Patients ask me about cost more often than they used to, and they deserve a straight answer instead of a shrug. Price is one of the real anxieties that comes with the word “surgery,” and pretending the numbers do not exist does not make them less frightening — it just leaves people guessing. The good news is that price data now exists in a way it did not a decade ago, thanks to federal transparency rules and independent research. The hard part is reading it honestly. So this is my attempt to lay out what the credible data actually shows about spine-surgery pricing in Indiana and nationally — and, just as importantly, what it does not show. If you want the practical, plan-by-plan version of this for our state, our cost of spine surgery in Indiana overview is the companion to this page.

What Indiana’s data actually shows

The most rigorous look at Indiana pricing comes from the RAND Corporation’s hospital price transparency studies, commissioned through the Employers’ Forum of Indiana. In their 2022 data, Indiana employers and private insurers paid 300 percent of what Medicare would have paid for the same hospital care — facility plus physician — which ranked as the ninth highest in the nation. For comparison, the national median that year was 253 percent of Medicare, with states ranging from 162 percent in Arkansas to 346 percent in Florida. An earlier RAND report had put Indiana at 292 percent of Medicare in 2020, the seventh highest in the nation, so this is a persistent pattern, not a one-year blip.

Here is the finding that surprises people most. When RAND separated the hospital’s facility charges from the physicians’ fees, facility prices alone were 338 percent of Medicare — the sixth highest in the nation — while physician payments were 127 percent of Medicare, the sixth lowest in the nation. Read that twice. In Indiana, the building and its overhead, not the surgeon’s fee, are what drive the high cost of care. When a spine operation carries a large price tag here, the facility line is doing most of the lifting.

The same operation, very different prices

The second big finding is variability. A 2024 study in the journal Neurosurgery examining 332 high-performing US spine centers found that the discounted cash price for a cervical spinal fusion ranged, across the middle half of centers, from $26,952 to $66,807. Gross charges for the same operation ranged from $48,492 to $99,293. That is not a rounding difference — it is the same procedure priced more than twice as high at one place as another. The study also found that only 8.4 percent of those centers were fully compliant with the federal price-transparency rule, which tells you how hard it still is for a patient to simply look the number up. The lesson is not that one hospital is cheating and another is virtuous; it is that price and value are not the same thing, and the only way to know your number is to ask for it in writing.

So what does “a spinal fusion” cost?

People want a single figure, so here is the most honest national one I can give. Turquoise Health, a price-transparency data company, publishes national average cash prices — what a self-pay patient is quoted, not the negotiated rate an insurer pays and not an Indiana-specific figure. By that measure, a cervical spinal fusion averages $47,699, a lumbar or thoracic spinal fusion (everything except cervical) averages $67,069, and a spine arthrodesis averages $26,113. Treat those as national reference points, not as a quote. Your insurer’s negotiated rate, your plan’s cost-sharing, and your specific facility can move the real number a long way in either direction — which is exactly why a written estimate beats any average.

The gap between private prices and Medicare keeps widening

None of this is happening in a vacuum. KFF’s analysis found that private insurance paid 267 percent of Medicare rates for hospital care on average in 2022. You will notice that is different from RAND’s 253 percent national median for the same year — the two use different methods and data, which is a good reminder that even careful analysts disagree, and that any single percentage is an estimate, not gospel. The trend line is the clearer story: private inpatient hospital prices grew 50 percent from June 2014 to December 2024, twice the 25 percent growth in Medicare’s rates over the same stretch. Commercial hospital prices are pulling away from Medicare, year after year, and Indiana sits near the front of that pack.

What this means for you as an Indiana patient

You cannot change RAND’s rankings, but you can control how you shop. A practical playbook:

• Get the exact planned procedure code. Ask your surgeon’s office for the specific CPT code for the operation being proposed, not a general description. Every estimate downstream depends on it.
• Ask each billing entity for a written estimate. A spine operation generates separate bills — surgeon, facility, and anesthesia — and each one can quote you. Under the federal No Surprises Act, self-pay patients are entitled to a good-faith estimate before a scheduled procedure, and it is reasonable for any patient to ask each biller for a written estimate.
• Ask whether an ambulatory setting is appropriate. Because the facility line drives Indiana’s cost, the site of care matters. For suitable patients and procedures, a surgery center often carries lower facility overhead than a hospital.
• Remember the biggest lever is the decision itself. No negotiation moves the math like changing the operation. A second opinion that finds a smaller procedure — or finds that you do not need surgery yet at all — changes your cost more than any line-item haggling. Our pages on whether you really need back surgery and alternatives to spinal fusion are built for exactly that question.

One caution: none of this means delaying care you actually need. Urgent problems — progressive weakness, loss of bowel or bladder control — come first, and price should never be the reason you sit on a red flag. Cost planning is for the elective, considered decisions, which is most spine surgery, not the emergencies.

What this data is, and what it is not

I want to be plain about the limits. Every figure above is an aggregate or a national average — a RAND ratio, a study’s interquartile range, a company’s cash-price benchmark. None of them is a quote for your operation, at your hospital, on your plan. A verified Indiana-specific dollar figure for a particular spine procedure is not something I can responsibly publish, because it does not exist in a trustworthy form — the honest way to get your number is a written estimate from each billing entity. Prices also change, methods differ between analysts, and nothing on this page is a promise about what any practice, including ours, will charge or what your insurance will cover. It is context, meant to help you ask sharper questions — starting with our spine surgery in Indiana overview, and if cost is your worry, our note on microdiscectomy cost with insurance.
