Spinal fusion is one of the few elective operations in American medicine where the same procedure can be a $17,000 outpatient bundle or a $290,000 hospital bill, and both numbers are real. The difference is not usually the surgeon. It is whether the case is sold as a package or billed as an admission, how many levels are fused, and whether the hardware sits inside the price or outside it.
This guide separates those using figures verified in September 2026: published cash prices from two surgery centers, the July 2026 CMS outpatient and ambulatory surgery center payment addenda, the FY2026 inpatient prospective payment rule tables, and 2024 Medicare inpatient claims released in April 2026. Read the exclusions carefully, because on a fusion they are worth five figures.
What Does Spinal Fusion Cost Without Insurance?
A one-level fusion sold as a cash bundle runs $17,384 to $38,000 depending on whether it is cervical or lumbar. A hospital inpatient stay for the same diagnosis is billed in a completely different range.

The cash bundles come from centers that publish them. Surgery Center of Oklahoma lists $17,384 for a one-level anterior cervical discectomy and fusion with hardware not included, and $38,000 for a one-level lumbar fusion, with no separate surgeon, facility or anesthesia bills. Newport Orthopedic Institute, whose rates apply at the Hoag Orthopedic Institute Surgery Center in Newport Beach, lists $27,300 for a one-level minimally invasive lumbar fusion and $39,900 for two levels, with facility, surgeon, anesthesiologist, 90 days of global follow-up, implants and intraoperative radiology all inside the number.
The hospital rows are average submitted charges from 2024 national Medicare inpatient claims released in April 2026. They are what hospitals asked for, not what anyone paid. The last row shows the gap: Medicare’s average total payment was $22,040 for a cervical fusion without complications against a $115,049 charge, and $59,155 for a non-cervical fusion with a major complication against a $289,773 charge.
What Drives the Price
Cervical versus lumbar, and how many levels
Under the July 2026 CMS ASC addenda, the ambulatory surgery center facility payment is $9,030.96 for CPT 22551 (single-level anterior cervical discectomy and fusion), $13,491.52 for CPT 22612 (single-level posterior lumbar fusion), and $20,841.42 for CPT 22633 (single-level lumbar fusion with both posterior and interbody technique, the code most transforaminal lumbar interbody fusions are billed under). That is a 2.3-fold spread inside one family of operations.
Every additional level adds another add-on code and more operating room time. Newport’s own list shows the effect on a real cash price: $27,300 for one level and $39,900 for two.
Where it is done
Facility setting matters as much here as anywhere in surgery. July 2026 OPPS Addendum B pays a hospital outpatient department $13,116.76 for CPT 22551 (APC 5115) and $27,721.73 for CPT 22633 (APC 5117), against the surgery center rates above. Add the 2026 physician fee schedule amount for the surgeon ($1,604.91 for 22551 and $1,700.11 for 22633, calculated as total RVUs times the $33.4009 conversion factor) and Medicare’s all-in totals run $10,636 versus $14,722 for a cervical fusion and $22,542 versus $29,422 for a lumbar one.
Both codes carry OPPS status indicator J1, which means Medicare pays them as comprehensive outpatient services rather than treating them as inpatient-only. The patient copayment on those is capped at the inpatient deductible of $1,736.00, which is CMS’s own way of admitting these are large bills.
Instrumentation and the interbody device
Hardware is the line item that separates two quotes for the same operation. Surgery Center of Oklahoma’s cervical and lumbar fusion prices are explicitly labelled hardware not included. Newport’s rates include plates, pins and screws, with additional fees possible for new technology.
Medicare treats these as separate billable services on the professional side too. In the 2026 physician fee schedule, inserting a biomechanical interbody device (CPT 22853) pays the surgeon $228.80 and anterior instrumentation across two or three segments (CPT 22845) pays $647.64, both as add-on codes with no global period. Those are small numbers next to the device invoices themselves, but they confirm that the cage and the screws are billed, not bundled by default.
Inpatient or outpatient, and length of stay
When a fusion is an admission, the hospital is generally paid one bundled amount by diagnosis-related group rather than by itemized charge, and the group depends on complications. Cervical fusions land in MS-DRG 471 (with major complication), 472 (with complication) and 473 (without either). The FY2026 IPPS final rule tables put the geometric mean length of stay at 7.1 days, 2.5 days and 1.6 days respectively, and relative weights at 4.8287, 2.9461 and 2.4413.
Non-cervical fusion is where the labelling gets confusing. The 2024 claims data still reports MS-DRG 459 and 460, but those two codes are not in the FY2026 final rule tables at all: single-level non-cervical fusion now sits in MS-DRG 450 and 451 (geometric mean stays of 6.3 and 2.4 days) and multiple-level in 447 and 448 (7.8 and 3.3 days). If someone quotes you a “DRG 460 price,” it is by construction built on an earlier grouper year.
Everything around the operation
A fusion quote is the operating room. The MRI that justified it, the pre-op visits, any injections tried first, the brace, and months of rehabilitation are separate. Our guides to MRI cost without insurance and physical therapy cost without insurance cover the two biggest of those, and if an overnight stay is on the table, hospital stay cost per day explains how room and board is priced separately from the procedure.
Cash Price vs. Insurance
Spinal fusion is expensive enough that the usual cash-versus-insurance calculation flips. A $17,384 cervical bundle is below most family deductible-plus-coinsurance exposure but a $38,000 lumbar bundle usually is not, so for a large fusion the honest answer is often that insurance wins, if you can get it authorized and if you can tolerate the network.
Where cash pricing helps is certainty. Every published bundle in this guide states in advance what it covers, which is exactly what a hospital estimate will not do. The hospital charge data above shows why that matters: an average submitted charge of $170,331 for a non-cervical fusion without a major complication, against an average Medicare payment of $27,838, means the sticker on an inpatient fusion has almost no relationship to any price anyone pays.
If you are uninsured or self-pay, federal No Surprises Act rules entitle you to a written Good Faith Estimate before a scheduled procedure. Get it in writing and ask specifically whether facility, surgeon, assistant, anesthesia, implants and any overnight stay are included. Our guide to hospital price transparency explains how to pull a hospital’s own posted cash rate before you ever call, and the same discipline is what makes anesthesia cost predictable instead of a surprise envelope six weeks later.
How to Pay Less
Ask whether your case can be done outpatient at all. The gap between a $27,300 outpatient bundle and a five-figure inpatient stay is the largest single lever available, and both CMS payment systems now treat these codes as outpatient-payable. Whether you personally qualify is a medical question for your surgeon, but it is worth asking directly rather than assuming.
Ask which CPT codes will be billed, then price them. 22551, 22612 and 22633 are three different tiers, roughly $9,000, $13,500 and $20,800 in facility payment alone. Knowing the code turns a vague quote into something you can compare. Run any number you receive through our fair price checker.
Get the hardware answer in writing. Two of the cash prices in this guide exclude implants and one includes them. On a two-level instrumented fusion, that is the difference between a comparable quote and a fantasy.
Ask for the self-pay discount before you schedule. Hospitals almost always have a posted uninsured discount applied on request rather than automatically. If a bill has already arrived, our medical bill negotiation guide and the negotiation script tool have the language, and requesting an itemized hospital bill first is what makes the negotiation possible.
Apply for charity care on a bill this size. Nonprofit hospitals must maintain financial assistance policies and the income thresholds are often well above the poverty line. On a six-figure inpatient charge, this is the tactic with the largest possible payoff. Our hospital charity care guide and the charity care checker show how to find and apply to a specific hospital’s program.
Price the non-fusion path first. Fusion is the end of a long line of options, and the earlier ones cost a fraction as much. Our guides to spinal decompression and chiropractor cost without insurance cover the conservative side, and physical therapy is billed per visit. What is medically right is a conversation with your surgeon; knowing what each option costs before that conversation is on you.
The Bottom Line
Budget $17,384 to $38,000 for a single-level fusion as an all-inclusive outpatient cash bundle as of September 2026, and about $39,900 for two lumbar levels with implants included. Cervical is the low end, lumbar the high end, and hardware is the exclusion that moves the number most.
If the operation happens as a hospital admission instead, throw the bundle math out. In 2024 national Medicare claims, hospitals billed an average of $115,049 for a cervical fusion without complications and $289,773 for a non-cervical fusion with a major complication, and were paid $22,040 and $59,155. That gap is the negotiating room, and it is why the paperwork matters as much as the surgery here. Smaller orthopedic operations follow the same setting-driven logic on a smaller scale, which is where our bunion surgery and knee replacement guides start.
