Lithotripsy is a non-invasive treatment that uses focused shock waves to break kidney stones into fragments small enough to pass in urine. Extracorporeal shock wave lithotripsy (ESWL) is the most common form and is usually done in under an hour as an outpatient. Kidney stones affect roughly 1 in 11 Americans according to the National Institutes of Health, and many patients who cannot pass a stone on their own are offered lithotripsy as an alternative to ureteroscopy or surgery. In 2026, the cash price depends far more on where the treatment is performed than on the stone itself.
Lithotripsy cost without insurance in 2026 is built from several separate bills: the facility fee, the urologist professional fee, anesthesia or sedation, imaging guidance (fluoroscopy or ultrasound), and any pre-procedure CT scan or follow-up x-ray. A freestanding lithotripsy center or mobile lithotripsy unit often quotes one bundled price, while a hospital outpatient department bills each component at chargemaster rates. Asking for the bundled price in writing is the single most effective way to avoid surprise charges.
The guide covers the 2026 cash price range, what Original Medicare pays, how to request a Good Faith Estimate under the No Surprises Act, self-pay discount options, and common billing errors. Federal protections are explained at CMS No Surprises Act and HealthCare.gov. Lithotripsy is billed under CPT code 50590, which is AMA-licensed, so no public HCPCS Level II code is listed on this page.
Lithotripsy Cost by Site of Service in 2026
The biggest cost driver of Lithotripsy is the site of service: where the procedure is performed. 2026 CMS price transparency data confirms a 2-3x billing differential between independent centers and hospital outpatient departments.
Lithotripsy prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Freestanding lithotripsy center or mobile unit | $1,800 to $4,500 | Facility rate set by Medicare ASC or physician-office rules, plus about $181 professional fee (2026) |
| Ambulatory surgery center (ASC) | $2,500 to $6,500 | ASC facility payment (2026), about 55% to 60% of the hospital OPPS rate |
| Hospital outpatient department | $5,000 to $14,000 | About $3,300 OPPS facility rate (2026, approximate) plus about $181 professional fee |
| Inpatient hospital (during admission) | $9,000 to $25,000 | Bundled in DRG |
Prices are typical 2026 ranges and vary by region, anesthesia type, and whether imaging or stent placement is included. Medicare figures marked approximate should be confirmed in the CMS look-up tools. Ranges reflect FAIR Health Consumer, KFF, and CMS hospital price transparency data.

Why the Same Procedure Is So Much More at a Hospital
The biggest cost driver of lithotripsy is the site of service: where the treatment is performed. 2026 lithotripsy cost at a freestanding center or mobile unit commonly runs $1,800 to $4,500, while the same ESWL session at a hospital outpatient department runs $5,000 to $14,000. The shock wave machine, the urologist, and the stone are identical. Hospitals add provider-based facility fees, higher overhead, and 340B and level-of-care assumptions that raise the billed price.
Hospital cash prices usually start at the chargemaster, the internal list price that almost no insurer pays in full. Commercial insurers negotiate rates far below it, and cash patients can ask for the hospital self-pay discount, often 20 to 60 percent off chargemaster according to hospital financial assistance policies. Hospitals must also post prices online under CMS price transparency rules, which gives patients a baseline for comparison.
Medicare pays a smaller gap between sites than cash markets do. The 2026 hospital OPPS facility rate is approximately $3,300 and the ASC rate is lower, but cash-pay spreads of 2 to 3 times are common. If your urologist operates at both a hospital and a lithotripsy center, scheduling at the center can save several thousand dollars without changing the treatment.
Kidney stone treatment cost by procedure type in 2026
Lithotripsy is one of several ways to treat kidney stones. The 2026 cost without insurance depends on which method your urologist recommends, and ESWL is generally the least expensive because it needs no incision and often no general anesthesia.
Typical cost by variant| Procedure | Typical range without insurance (2026) | Typical setting | Anesthesia |
|---|
| Shock wave lithotripsy (ESWL) | $1,800 to $14,000 | Lithotripsy center or hospital outpatient | Sedation or light anesthesia |
| Ureteroscopy with laser lithotripsy | $6,000 to $20,000 | ASC or hospital outpatient | General anesthesia |
| Percutaneous nephrolithotomy (PCNL) | $15,000 to $40,000 | Hospital, often overnight stay | General anesthesia |
| Ureteral stent add-on | $500 to $3,000 | Same session | Included with procedure |
Ranges are approximate 2026 national cash-price benchmarks. Stones larger than about 2 centimeters or located in the lower pole may call for ureteroscopy or PCNL instead of ESWL.

What Medicare Pays for Lithotripsy
Original Medicare covers medically necessary lithotripsy under Medicare Part B when a physician documents a stone that causes symptoms or blockage. The 2026 Medicare Physician Fee Schedule pays the urologist roughly $181 for CPT 50590 (approximate national rate), and the 2026 hospital outpatient OPPS facility rate is approximately $3,300. After the 2026 Part B deductible of $283, the patient owes 20% coinsurance. Medigap supplement plans typically pay that 20% coinsurance, and Medicare Advantage plans set their own copays, so check the plan Summary of Benefits and prior authorization rules.
Commercial insurance treats lithotripsy as a diagnostic-and-treatment service, not a preventive one. Lithotripsy is not a USPSTF preventive service, so an ACA-compliant plan applies your deductible, copay, and coinsurance. Patients on a high-deductible health plan usually pay the full negotiated rate until the deductible is met, often $1,650 to $3,500 or more in 2026. In-network facilities and urologists cost far less than out-of-network, and many commercial and Medicare Advantage plans require prior authorization. Anesthesia and radiology can bill separately, so confirm each is in network.
The No Surprises Act, effective January 1, 2022, gives every uninsured or self-pay patient the right to a written Good Faith Estimate before a scheduled lithotripsy. If the procedure is scheduled at least 10 business days out, the provider must furnish the Good Faith Estimate at least 3 business days before service. If it is scheduled 3 to 9 business days out, the estimate is due at least 1 business day before service. Federal guidance is at cms.gov/nosurprisesact (https://www.cms.gov/nosurprisesact). Medicare and Medicaid beneficiaries have separate protections.
To request a Good Faith Estimate for lithotripsy in 2026, follow these steps: (1) Call the lithotripsy center, hospital, or urology office and say you are self-pay or uninsured. (2) Ask for a written Good Faith Estimate listing the procedure code, the facility fee, the urologist fee, anesthesia, imaging, and any stent or pathology charges. (3) Give your ZIP code and planned add-ons such as a ureteral stent or stone analysis. (4) Confirm the timing: 3 business days before service if scheduled 10 or more business days out, or 1 business day if scheduled 3 to 9 business days out. (5) Keep the written estimate; if the final bill exceeds it by $400 or more, you can file a patient-provider dispute within 120 days of the bill date.
A Good Faith Estimate for lithotripsy is not a guaranteed final bill. Common reasons actual charges exceed the estimate include a repeat ESWL session when stone fragments remain, conversion to ureteroscopy, ureteral stent placement, longer-than-expected anesthesia time, extra imaging during the same encounter, and stone analysis not in the original estimate. If the final bill exceeds the Good Faith Estimate by $400 or more, the patient has 120 days from the bill date to file at the federal portal (https://www.cms.gov/nosurprisesact/help-resolve-payment-disputes/patient-provider).
What Factors Affect Cost
- Site of service: a freestanding lithotripsy center or ASC costs roughly 30 to 60 percent less than a hospital outpatient department for the same ESWL session in 2026.
- Stone size, location, and number of sessions: large or lower-pole stones may need a second ESWL session or ureteroscopy, which can double the total cost.
- Insurance status: uninsured cash price versus in-network commercial rate versus Medicare. High-deductible plans usually mean paying the full negotiated rate until the deductible is met. Medicare Advantage and commercial plans often require prior authorization.
- Independent center cash bundles: freestanding lithotripsy centers and mobile lithotripsy providers often quote one all-in price that includes the facility, urologist, and basic imaging, typically 30 to 60 percent below the hospital chargemaster cash price. Ask whether anesthesia is included.
- Hospital chargemaster discount ask: most hospitals have a published self-pay or financial assistance policy, often 20 to 60 percent off chargemaster. Some apply it automatically to uninsured patients, others require you to request it before the procedure.
- Sliding-scale FQHCs and charity care: Federally Qualified Health Centers charge by household size and income, and nonprofit hospitals must have charity care policies. Eligibility uses the federal poverty level, so see the CoveredUSA federal poverty level guide. FQHCs usually refer lithotripsy out, but can help with the urology visit and imaging.
- Anesthesia, imaging, and stent charges: sedation, pre-procedure CT or ultrasound, fluoroscopy guidance, and a ureteral stent can each be billed separately. No state-run screening program applies because lithotripsy treats existing stones and is not a screening service.
Common Lithotripsy Billing Errors
Lithotripsy bills combine facility, professional, anesthesia, and imaging components, which creates several predictable errors. Check for these before paying:
- Imaging guidance billed separately when it is already bundled into the ESWL code. Ask for an itemized bill and challenge duplicate fluoroscopy charges.
- Hospital outpatient facility rate billed for a session performed at a mobile lithotripsy unit or affiliated center.
- Anesthesiologist billed out-of-network at an in-network facility. The No Surprises Act may protect insured patients, so do not pay before checking.
- A repeat ESWL session billed as a new procedure outside the global period when it should fall under the same treatment plan.
- Ureteral stent or stone analysis charged at list price when it was never listed on the Good Faith Estimate.
Frequently Asked Questions
How much does lithotripsy cost without insurance in 2026?
Without insurance in 2026, shock wave lithotripsy typically costs about $1,800 to $14,000, with a national median near $5,200. A freestanding lithotripsy center or mobile unit often charges $1,800 to $4,500, while a hospital outpatient department charges $5,000 to $14,000. Separate bills for anesthesia, imaging, a ureteral stent, or stone analysis can add $500 to $3,000. Ask for a bundled cash price in writing before scheduling.
What does Medicare pay for lithotripsy in 2026?
Under Original Medicare in 2026, Medicare Part B pays the urologist roughly $181 under the Physician Fee Schedule and a hospital outpatient facility rate of approximately $3,300 under OPPS. You owe 20% coinsurance after the $283 Part B deductible. Medigap plans typically cover that 20%, while Medicare Advantage plans set their own copays and may require prior authorization. Confirm current rates in the CMS Physician Fee Schedule look-up tool.
How do I request a Good Faith Estimate for lithotripsy?
Call the lithotripsy center, hospital, or urology office, identify yourself as self-pay or uninsured, and ask for a written Good Faith Estimate listing the procedure code, facility fee, urologist fee, anesthesia, imaging, and any stent. Provide your ZIP code and planned add-ons. The estimate is due 3 business days before service if scheduled 10 or more business days out, or 1 business day before if scheduled 3 to 9 business days out. Keep it for any dispute.
What is the No Surprises Act and does it apply to me?
The No Surprises Act, effective January 1, 2022, protects patients from surprise out-of-network bills and gives uninsured and self-pay patients the right to a Good Faith Estimate. It applies to hospitals, ASCs, imaging centers, and physician offices. If your final lithotripsy bill exceeds the Good Faith Estimate by $400 or more, you can file a patient-provider dispute within 120 days. It does not cover Medicare or Medicaid, which have separate protections. See cms.gov/nosurprisesact.
How do I get a written cash-pay quote for lithotripsy?
Call the facility before scheduling and ask, What is your self-pay cash price for shock wave lithotripsy? Ask whether it includes the urologist, anesthesia, fluoroscopy or ultrasound, and a possible stent. Request the quote by email or letter, and request a Good Faith Estimate to make it formal. Get quotes from at least one freestanding lithotripsy center and one hospital, since cash prices can differ by 2 to 3 times.
Can I negotiate a lithotripsy bill after the fact?
Yes. Patients can negotiate after a bill arrives, and offers to pay promptly often earn reductions of 30 to 50 percent. Request an itemized bill, compare it to your Good Faith Estimate, ask for the hospital self-pay or financial assistance discount off chargemaster, and ask for a payment plan. If the bill exceeds the estimate by $400 or more, you can file a patient-provider dispute within 120 days at the federal portal.
What is the difference between hospital and lithotripsy center cost?
The 2026 cash price for lithotripsy at a freestanding center or mobile unit is typically $1,800 to $4,500, versus $5,000 to $14,000 at a hospital outpatient department. The treatment is the same, but hospitals bill provider-based facility fees and chargemaster rates. Medicare pays about $3,300 for the hospital facility fee under the 2026 OPPS. If your urologist works at both sites, ask to schedule at the center.
Will my insurance cover lithotripsy?
Usually yes when it is medically necessary. Lithotripsy is not a USPSTF preventive service, so ACA-compliant plans apply your deductible, copay, and coinsurance. Many commercial and Medicare Advantage plans require prior authorization. Original Medicare covers it under Part B at 20% coinsurance after the $283 deductible in 2026. Confirm that the facility, urologist, and anesthesiologist are all in network.
What is the difference between lithotripsy and ureteroscopy?
Shock wave lithotripsy (ESWL) breaks stones from outside the body with no incision and typically costs $1,800 to $14,000 in 2026. Ureteroscopy passes a scope through the urethra and bladder and breaks the stone with a laser, usually under general anesthesia, costing about $6,000 to $20,000. ESWL suits smaller stones in the kidney or upper ureter, while ureteroscopy is more reliable for larger, harder, or lower-pole stones.
Will I need more than one lithotripsy session?
Sometimes. Roughly 1 in 4 patients needs a repeat ESWL session, depending on stone size and composition. Ask whether a second session is included in the bundled cash price or billed separately, and request that any repeat treatment be listed in the Good Faith Estimate. Unplanned additional sessions are a common reason the final bill exceeds the estimate.
