How Much Does a Kidney Stone Treatment Cost in 2026?
Without insurance, a kidney stone treatment typically costs $2,500 to $15,000. With insurance, most people pay about $500 to $7,500 out of pocket, depending on their plan and where they go.
- Cash-pay bundles for ureteroscopy or lithotripsy run about $6,600-$12,300 at a surgery center, versus $15,000-$45,000+ in hospital chargemaster prices.
- Where you have it done matters most: an ASC or urology office is far cheaper than a hospital for the same procedure.
- Medicare allows roughly $3,000-$4,200 for the main procedure; insured patients typically pay $500-$7,500 out of pocket depending on their deductible.
Kidney Stone Treatment Cost by Where You Go
Cash / self-pay price ranges. Where you have the procedure is usually the biggest factor.
| Where | Cash price |
|---|---|
| Hospital (outpatient surgery or inpatient) | $9,000 to $18,000 |
| Ambulatory surgery center (ASC) | $6,000 to $12,000 |
| Urology office / clinic | $2,000 to $6,000 |
| Emergency room (diagnosis only) | $3,000 to $12,000 |
Lowest price: A cash-pay bundle at an ambulatory surgery center (via MDsave or a direct self-pay quote), or an in-office urology clinic for minor stent/cystoscopy procedures.
What Makes Up the Bill
Total billed before insurance is typically $12,000 to $45,000. It is usually split across:
Medicare-allowed for CPT 52356 (ureteroscopy + laser lithotripsy + stent) runs roughly $3,000-$4,200 total: about $2,520 ASC facility (or ~$3,600+ hospital outpatient) plus a ~$370-$490 urologist fee; ESWL (50590) is similar. Under Original Medicare you pay 20% coinsurance, and the hospital outpatient copay is capped at about $1,676 per service.
With vs. Without Insurance
Without insurance (self-pay)
$2,500 to $15,000
Ask for the cash or prompt-pay price up front. It is often far below the billed amount.
With insurance (out of pocket)
$500 to $7,500
If you are insured and in-network, you pay your plan's contracted rate, not the chargemaster price: your deductible, then coinsurance up to your out-of-pocket maximum (commonly $5,000-$9,450 individual for 2026). A surgical stone case frequently hits that maximum. Out-of-network care (a common surprise with ER radiologists or anesthesiologists) can cost far more, so confirm every provider's network status when possible. This is an estimate, not a quote; verify with your plan and provider.
Prices vary widely by region and facility. Hospital charges for ESWL alone have been documented from about $432 to $49,522 across the country. High-cost metros (Northeast, California) and hospital-based settings run at the top of every range, while ASCs and lower-cost regions can be less than half. Always compare local Good Faith Estimates rather than relying on a national average.
How to Pay Less
Ask for a cash / self-pay bundled price
Pre-negotiated bundles (e.g., MDsave) for lithotripsy or ureteroscopy run about $6,600-$12,300 all-in, versus $15,000-$45,000 chargemaster. Cash rates are often 40-80% off list.
Choose an ASC over a hospital
The same urologist at an ambulatory surgery center usually charges 30-50% less in facility fees. Ask if your case can be scheduled there instead of the hospital.
Get a Good Faith Estimate and compare
Federal law entitles self-pay patients to a written Good Faith Estimate. Prices vary enormously (one study showed ESWL from $432 to $49,522), so shop 2-3 facilities.
Try to pass small stones first
Stones under ~5mm often pass on their own with hydration, pain meds, and tamsulosin, avoiding a procedure entirely. Ask your doctor if watchful waiting is safe.
Review the itemized bill for errors
Kidney-stone claims frequently contain overcharges and duplicate/unbundled line items. Request an itemized bill and dispute anything that looks wrong before paying.
Check hospital charity care, or get the bill reduced
Uninsured or lower income? Many hospitals offer free or discounted care. Use the charity care finder to see if you qualify nearby. Already billed? CareRoute Bill Defense reviews and negotiates it down, with no fee unless we save you money.

Open the cost estimatorFrequently Asked Questions
What is the difference in cost between ureteroscopy and shockwave lithotripsy (ESWL)?
They are similar in price. Cash bundles for both typically run about $6,600-$12,300 at an ASC. Ureteroscopy (with a laser and stent) can bill somewhat higher because of the stent and OR time, while ESWL is non-invasive. Your urologist picks the method based on stone size, location, and composition, not just cost.
Will I need a ureteral stent, and does it cost extra?
Stents are common after ureteroscopy to keep the ureter open while it heals. Placement is usually included in the surgical bundle, but removal (a quick office cystoscopy) may be billed separately, often a few hundred dollars.
How much is just the ER visit for a kidney stone?
An ER visit to diagnose a stone typically runs $3,000-$12,000, driven by the facility fee and a CT scan ($500-$3,000). The ER usually only diagnoses and manages pain; the actual stone treatment is scheduled separately with a urologist.
Does insurance cover kidney stone treatment?
Yes. Kidney stone removal is medically necessary and covered by essentially all plans, including Medicare and Medicaid. Your out-of-pocket depends on your deductible and coinsurance; a surgical case often pushes you to your annual out-of-pocket maximum.
Can I avoid surgery altogether?
Often, yes. Stones smaller than about 5mm pass on their own in most cases with fluids, pain control, and medications like tamsulosin. Surgery is reserved for larger stones, ones causing blockage or infection, or pain that will not resolve.
