“You need surgery for that stone” is not one price. It is three completely different procedures with completely different bills, and most people are told they need surgery before anyone tells them which one.

The three are shockwave lithotripsy (ESWL, billed as CPT 50590), ureteroscopy with stone removal or laser lithotripsy (CPT 52352 and 52353), and percutaneous nephrolithotomy or PCNL (CPT 50080 and 50081). They differ by about four times in price. Layered on top of all three is a ureteral stent, which is billed separately going in and billed again coming out, and which is the single most common reason a kidney stone removal estimate turns out to be low. Every figure below was verified on September 3, 2026.

What Does Kidney Stone Surgery Cost Without Insurance?

Bundled cash prices come from MDsave’s national pages, read September 3, 2026. Hospital cash prices for ureteroscopy come from a JAMA Network Open analysis of price transparency files at 153 academic medical centers, pulled from Turquoise Health on March 24, 2022. Medicare figures come from the CMS Medicare Physician and Other Practitioners and Medicare Outpatient Hospitals datasets for claim year 2024, released in 2026. Drug acquisition cost comes from CMS NADAC effective August 19, 2026.

Lithotripsy, ureteroscopy and PCNL are three different bills

The sources disagree, and the disagreement is the story. For shockwave lithotripsy, Medicare’s average allowed amount on a hospital outpatient claim was $3,250.32 in 2024, MDsave’s bundled cash price ranged $6,605 to $12,292 in September 2026, and hospitals submitted average total charges of $27,395.90 on those same Medicare claims. Those are three real numbers describing the same operation. The chargemaster number is the one nobody actually pays, and the one that shows up on an uninsured patient’s first bill.

For ureteroscopy the two independent sources land close together, which is unusual and reassuring. The JAMA Network Open cash median of $4,784 for CPT 52353 and Medicare’s 2024 average allowed amount of $4,815.56 for the same code are within one percent of each other. Call $4,800 the honest center of gravity for a ureteroscopy with laser lithotripsy, with real prices running from about $3,100 to about $9,800.

The surgeon is not the expensive part

This surprises almost everyone. Medicare’s 2024 national average allowed amounts for the operating urologist were $729.22 for shockwave lithotripsy, $375.99 for ureteroscopy with stone removal, $556.71 for ureteroscopy with laser lithotripsy, and $676.01 for complex PCNL. All four are under $750.

Virtually everything else on a kidney stone surgery bill is the building, the anesthesia, and the disposable equipment. That matters practically, because it tells you where to aim when you negotiate: the facility fee, not the physician fee.

The stent is the line item that breaks estimates

After a ureteroscopy or a lithotripsy, a urologist often leaves a thin flexible tube called a ureteral stent in place, which NIDDK describes as helping urine flow or a stone pass. It is billed separately.

In Medicare’s 2024 physician data, stent placement (CPT 52332) was billed 127,825 times in the facility setting, more often than any of the stone procedures themselves, with an average submitted charge of $1,866.49. On the hospital side, claims that paid for stent placement carried average total submitted charges of $21,906.33 against an average Medicare allowed amount of $3,302.31.

Then it has to come out. Stent removal (CPT 52310) was billed 55,088 times in an office setting, with an average submitted charge of $970.08 and an average Medicare allowed amount of $301.90. If a quote for your stone surgery does not mention the stent or the removal visit, it is not a complete quote.

What Drives the Price

Which kidney stone removal you get. This is the largest factor by far. PCNL bundles cost roughly twice a lithotripsy bundle and three to four times a ureteroscopy. NIDDK notes that PCNL is done in a hospital under anesthesia and may require a hospital stay of several days, while lithotripsy and ureteroscopy are usually same-day.

Where it is done. A hospital outpatient department is the most expensive setting, an ambulatory surgery center is cheaper, and the same CPT codes are used in all of them. Medicare’s 2024 data shows shockwave lithotripsy paying an average of $595.41 to the surgeon in a non-facility setting versus $729.22 in a facility, but the facility fee on top is what actually moves the total.

Anesthesia. All three procedures generally involve anesthesia, and the anesthesiologist bills separately from the surgeon and the facility. It is a third bill and it is rarely in the quote.

Imaging before and after. A stone-protocol CT of the abdomen and pelvis (CPT 74176) carried an average submitted charge of $813.89 in an office in Medicare’s 2024 data, against an average allowed amount of $136.21. Many patients get more than one. Our CT scan cost guide and ultrasound cost guide cover the self-pay prices for both, and ultrasound is often the cheaper follow-up.

How you arrive. Arriving through the emergency department attaches an ER visit bill to the whole episode, plus imaging at ER prices. Arriving through a scheduled urology appointment does not.

Cash Price vs. Insurance

Kidney stone surgery is one of the procedures where paying cash is sometimes, but not usually, the better deal. The JAMA Network Open study of 153 academic hospitals found the posted cash price was the lowest of the four price classes at just 10 percent of hospitals for ureteroscopy with laser lithotripsy and 7 percent for transurethral prostate surgery. The same study found that only 30 percent of those hospitals posted any ureteroscopy price at all.

So the cash price beats insurance at a minority of hospitals, but the minority is not trivial, and you cannot know which kind of hospital you are dealing with without asking for both numbers. Ask for the discounted cash price in writing and compare it against what your plan says you will owe after the deductible.

The catch is the usual one. Cash payments do not count toward your deductible or your out-of-pocket maximum. If a stone episode has already pushed you close to either, running the claim is almost always better. If you are uninsured, the cash price is the only number that matters, and it is negotiable. Run any quote through our fair price checker first.

How to Pay Less

  1. Ask which procedure, in writing, before you price anything. “Kidney stone surgery” spans a four-times price range. Ureteroscopy, shockwave lithotripsy and PCNL are different bills, and the CPT code on the estimate tells you which one you are being quoted.

  2. Ask for a bundled cash price that names the stent. MDsave’s national bundles ran $6,605 to $12,292 for lithotripsy and $12,419 to $21,144 for PCNL on September 3, 2026, against MDsave’s own stated conventional national averages of $16,911 and $32,101. Bundled prices move between reads, so confirm on the day you buy, and confirm whether stent placement and removal are inside the bundle.

  3. Price a surgery center against the hospital. The same procedure codes are billed in both, and the facility fee is where the difference sits. Every hospital must publish a machine-readable file with its discounted cash price; our guide to hospital price transparency explains how to find and read one before you schedule.

  4. Get an itemized bill and check the facility line first. Medicare’s data shows the surgeon’s allowed amount is under $750 for all of these procedures, so a five-figure bill is almost entirely facility and supply charges. Our guide to reading an itemized hospital bill shows what to look for, and our guide to negotiating medical bills covers what to say once you find it.

  5. Apply for charity care before you agree to a payment plan. Nonprofit hospitals are required to have a financial assistance policy, and stone surgery bills routinely qualify. Start with our hospital charity care guide and the charity care checker, and do it before the bill moves to collections rather than after.

  6. Know that not every stone becomes an operation. NIDDK states that small kidney stones may pass without treatment and that a clinician may advise fluids and prescribe pain medicine. If that is the path your urologist recommends, the drug cost is trivial: tamsulosin, the drug most often used to help a stone pass, costs $0.05093 per capsule in CMS acquisition data effective August 19, 2026, or about $1.53 for a 30-day supply. Whether waiting is safe in your case is a question for your urologist, not for a price guide.

Bottom Line

Budget roughly $3,100 to $9,800 for a ureteroscopy, $6,600 to $12,300 for shockwave lithotripsy, and $12,400 to $21,100 for PCNL as a self-pay patient, and add the stent placement and the stent removal visit on top unless a written quote says otherwise.

The first question to ask is which procedure. The second is whether it can be done at a surgery center instead of a hospital. The third is what the stent adds. Those three answers explain most of the difference between a $4,000 bill and a $20,000 one. If a cystoscopy is part of the workup, our cystoscopy cost guide covers that separately, and if you are pricing other urology procedures in the same visit, our UroLift cost guide shows how much the same place-of-service question changes an enlarged-prostate bill.
