How Much Does Endometriosis Surgery Cost in 2026?
Without insurance, endometriosis surgery typically costs $8,000 to $20,000, and more for complex cases, depending on the approach and where it is done. With insurance, most people pay about $2,000 to $7,500 out of pocket.
- The approach drives the price: a diagnostic laparoscopy to confirm endometriosis is usually cheapest, a laparoscopic excision or ablation of lesions costs more, and a complex case with bowel or bladder involvement that needs more than one specialist is the most expensive.
- Excision (cutting the lesions out) is generally more involved and more expensive than ablation (burning the surface), and deep infiltrating disease done by a specialist center sits at the top of the range.
- Billed/chargemaster charges (often $20,000-$45,000+) are far above what insurers, Medicare, or negotiated cash payers actually pay, so never treat the list price as final.
Endometriosis Surgery Cost by Approach
Cash / self-pay price ranges. The approach, the severity of disease, and how many specialists are involved are the biggest factors.
| Approach | Cash price |
|---|---|
| Diagnostic laparoscopy (outpatient) | $5,000 to $15,000 |
| Laparoscopic ablation of lesions (outpatient) | $8,000 to $18,000 |
| Laparoscopic excision of lesions (outpatient) | $12,000 to $25,000 |
| Complex / deep infiltrating case (bowel or bladder) | $25,000 to $50,000+ |
Lowest price: A same-day diagnostic laparoscopy, or a bundled cash-price excision or ablation at an outpatient surgery center. If a hysterectomy is being considered for severe disease, that is a separate, larger decision, not an endometriosis excision.

What Makes Up the Bill
Total billed before insurance is typically $20,000 to $45,000, and higher for complex cases. It is usually split across:
The single biggest lever is the facility fee, which is why an outpatient surgery center is far cheaper than an inpatient hospital stay. A complex case that adds a colorectal or urologic surgeon brings a second surgeon's fee and can require an overnight stay, each night adding roughly $2,000 to $4,000. Removed tissue is almost always sent to pathology, which is billed separately.
With vs. Without Insurance
Without insurance (self-pay)
$8,000 to $20,000
Ask for the cash or prompt-pay price up front, and ask specifically whether an outpatient laparoscopic excision or ablation fits your case. It is often far below the billed amount. Complex deep-infiltrating cases run higher.
With insurance (out of pocket)
$2,000 to $7,500
With commercial insurance, an in-network, medically necessary endometriosis surgery leaves you owing your deductible plus coinsurance up to your annual out-of-pocket maximum, commonly $2,000-$7,500 total (the average reported out-of-pocket is around $5,000). Confirm the surgeon, facility, AND anesthesiologist are all in-network to avoid balance/surprise bills, and get prior authorization. Medicare beneficiaries owe about 20% coinsurance after the Part B deductible for outpatient cases unless a Medigap plan covers it.
Prices vary widely by region and by provider. Within a single metro, hospital-reported cash prices for the same endometriosis surgery code can differ by several times over, so shopping 3-4 local facilities and asking each for an all-in price matters more than your region alone.
How to Pay Less
Ask whether it can be done in one outpatient operation
A diagnostic laparoscopy and the excision or ablation can often be combined into a single same-day procedure, so you pay one facility and anesthesia fee instead of two. Ask your surgeon whether your imaging already supports treating at the same time, and what approach fits the location and depth of your lesions.
Choose an outpatient surgery center when eligible
An ambulatory surgery center carries a much lower facility fee than a hospital. For a same-day laparoscopic excision or ablation that does not involve the bowel or bladder, it is usually the lowest-cost venue.
Request an all-in bundled cash price in writing
Uninsured patients are billed the full chargemaster rate, often 2-3x the negotiated rate. Ask for a single bundled price that includes the surgeon, anesthesia, facility, and pathology so there are no surprise add-ons. Hospitals commonly cut 30-60% for cash paid upfront.
Compare facilities using price-transparency files
Federal rules require hospitals to post machine-readable cash prices. Reported prices for the same endometriosis surgery code range widely, so shopping 3-4 local facilities can save thousands.
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.
Frequently Asked Questions
Does insurance cover endometriosis surgery?
Yes, when it is medically necessary (for example, chronic pelvic pain, heavy bleeding, lesions found on imaging, or endometriosis affecting fertility), surgery is covered by essentially all commercial plans, Medicare, and Medicaid. This includes diagnostic laparoscopy and laparoscopic excision or ablation of lesions. Your out-of-pocket is your deductible plus coinsurance, capped by your plan's annual out-of-pocket maximum, typically $2,000 to $7,500. Get prior authorization first.
What is the cheapest way to treat endometriosis surgically?
A same-day outpatient laparoscopy, where the surgeon confirms the diagnosis and treats the lesions in the same operation, is usually the least expensive path because it needs no inpatient stay and no second procedure. Combining the diagnostic and treatment steps avoids paying twice for the facility and anesthesia. The right approach depends on the location and depth of your lesions, not on cost alone.
Why does excision cost more than ablation?
Excision cuts the lesions out, including deeper disease, and takes more operating time and skill, so it is often done by a specialist and bills higher than ablation, which burns the surface of the lesions. Many surgeons favor excision for deep or extensive disease because it can be more thorough. Ask your surgeon which approach fits your case and request the cash or expected out-of-pocket price for each.
Why is the billed amount so much higher than what people actually pay?
The chargemaster (list) price is a starting point almost no one pays. Billed charges for endometriosis surgery commonly run $20,000 to $45,000 or more, but insurers pay negotiated rates and Medicare pays a few thousand dollars for outpatient cases. Cash patients should always negotiate off the billed amount or ask for an all-in bundled price.
How much does Medicare pay for endometriosis excision (CPT 58662)?
Under the 2026 Medicare Physician Fee Schedule, the surgeon's fee is about $647 for a laparoscopic excision or ablation of endometriosis lesions (CPT 58662). The hospital facility fee is billed separately and is larger, so Medicare's total approved amount for an outpatient case is typically a few thousand dollars, with you responsible for about 20% coinsurance after the Part B deductible (a Medigap plan can cover that).
