Most people with health insurance pay between $1,500 and $5,000 out of pocket for ACL surgery, depending on their plan’s deductible, copay structure, and whether they’ve already met part of their deductible for the year. The total billed cost before insurance averages around $14,800 nationally, but your insurance plan negotiates that down significantly, and you’re responsible only for your cost-sharing portion up to your plan’s out-of-pocket maximum.
What ACL Surgery Actually Costs Before Insurance
The national average cost of ACL reconstruction is roughly $14,800, according to data from the Health Care Cost Institute. That figure includes the surgeon’s fee, the facility charge, anesthesia, and basic supplies. It does not typically include pre-surgery imaging like an MRI, physical therapy afterward, or the follow-up visits that stretch across several months of recovery.
Where you live changes the price substantially. Outpatient ACL surgery at an ambulatory surgical center ranges from about $6,269 in Iowa (the least expensive state) to $8,913 in Alaska (the most expensive), based on 2023 pricing data from Sidecar Health. Hospital-based procedures run higher. Research comparing outpatient and inpatient ACL reconstruction consistently shows savings of 18% to 58% when the surgery is performed at a freestanding surgical center rather than a hospital. One study found mean costs of roughly $3,900 at an outpatient center versus $9,200 at a hospital for the same procedure.
How Insurance Reduces Your Bill
ACL reconstruction is considered medically necessary when imaging confirms a torn ligament and conservative treatment hasn’t restored knee stability. That means most commercial insurance plans, Medicare, and Medicaid cover it. Your actual out-of-pocket cost depends on three numbers in your plan: the deductible, the coinsurance or copay rate, and the out-of-pocket maximum.
Here’s how it works in practice. Say your plan has a $2,000 deductible and 20% coinsurance, and your insurer’s negotiated rate for the surgery is $10,000. You pay the first $2,000 (your deductible), then 20% of the remaining $8,000 ($1,600), for a total of $3,600. If you’ve already met part of your deductible earlier in the year from other medical expenses, your share drops accordingly. And if your plan’s out-of-pocket maximum is $4,000, you’ll never pay more than that in a single year regardless of what additional rehab or follow-up visits cost.
High-deductible health plans paired with a health savings account (HSA) often mean a larger upfront share. If your deductible is $3,000 or $5,000, you could owe most of that before coinsurance kicks in. On the other hand, plans with lower deductibles and fixed copays for surgery (sometimes a flat $250 to $500 per procedure) can bring the total well under $2,000.
Graft Type Affects the Total
Your surgeon will reconstruct the torn ligament using either tissue from your own body (an autograft, typically harvested from the patellar tendon or hamstring) or donor tissue from a tissue bank (an allograft). The choice affects both recovery and cost. A study published in the American Journal of Sports Medicine found the mean hospital cost was $4,072 for autograft and $5,195 for allograft, a difference of about $1,123. That gap comes from the processing and procurement fee for donor tissue.
Whether that cost difference passes through to you depends on how your insurance handles it. If you’ve already met your deductible, the difference in your coinsurance share is modest. If you haven’t, the higher total cost of an allograft means a slightly larger bill. Your surgeon typically recommends one graft type over the other based on your age, activity level, and anatomy, so cost alone shouldn’t drive the decision.
Hidden Costs to Watch For
The surgical bill is the largest single expense, but it’s not the only one. A pre-surgery MRI typically costs $500 to $1,500 before insurance. Physical therapy afterward is essential and usually runs two to three sessions per week for three to six months. Each session may carry a $30 to $75 copay depending on your plan, which adds up to $700 to $2,500 over the course of rehab. A knee brace, crutches, and follow-up office visits add smaller amounts.
One cost that used to catch patients off guard was surprise billing from out-of-network anesthesiologists or surgical assistants who happened to be working at your in-network facility. The No Surprises Act, which took effect in 2022, largely eliminates this problem. Under the law, insured patients cannot be billed out-of-network rates for ancillary services like anesthesia, radiology, or assistant surgeons at in-network facilities, including ambulatory surgical centers. You’re protected whether the setting is a hospital or a private surgical center.
How to Estimate Your Specific Cost
The most reliable way to get your number is to call your insurance company before scheduling surgery. Ask for a pre-authorization and a cost estimate based on the specific procedure code your surgeon’s office provides (it’s usually CPT code 29888 for arthroscopic ACL reconstruction). Your insurer can tell you the negotiated rate, how much of your deductible remains, and what your coinsurance share will be.
If you want to reduce your out-of-pocket cost, consider these levers. First, ask your surgeon if the procedure can be done at an ambulatory surgical center rather than a hospital. Facility fees are significantly lower and your coinsurance share drops with them. Second, if your surgery isn’t urgent, scheduling it later in the year after you’ve accumulated other medical expenses toward your deductible can save hundreds or thousands. Third, confirm that every provider involved, including the anesthesiologist and any assistant surgeon, is in your insurance network. Even with No Surprises Act protections, staying in-network simplifies billing and avoids disputes.
If you have a high-deductible plan, check whether your employer offers an HSA or flexible spending account. Both let you pay medical expenses with pre-tax dollars, effectively giving you a 20% to 35% discount depending on your tax bracket. Some surgical centers also offer payment plans that spread your out-of-pocket portion over six to twelve months with no interest.
