If you might have appendicitis, do not wait to compare prices. Sudden pain that starts near the navel and shifts to the lower right abdomen, especially with fever, nausea, vomiting, or pain that worsens with movement, needs urgent evaluation. Go to the emergency room or call 911. A ruptured (perforated) appendix is far more dangerous — and far more expensive — than one treated early. The cost information below is to help you manage the bill afterward, not to help you decide whether to seek care.
Appendicitis strikes without warning, and an appendectomy cost reflects the urgency of the situation — most are emergency procedures with little time for price shopping or cost comparison. As of early 2026, without insurance an appendectomy typically costs $10,000 to $35,000, depending on whether it’s performed laparoscopically or as open surgery and whether complications like perforation extend the hospital stay. Even with good insurance, out-of-pocket costs commonly reach $2,000 to $8,000 after deductibles and coinsurance. These are estimates that vary widely by hospital and region, so always verify with your specific facility and plan. Because appendicitis is almost always an emergency, the pricing dynamics differ significantly from elective procedures where patients can plan and compare. Our healthcare costs guide explains how emergency vs. planned surgery pricing works in the US system.
The short version: As of early 2026, an appendectomy runs an estimated $10,000 to $35,000 without insurance and commonly $2,000 to $8,000 out of pocket with insurance, with complicated cases costing much more. Because it is emergency, medically necessary care, it is essentially always covered — so never delay treatment over cost. This article offers general cost information, not medical advice; all prices are estimates that vary by hospital and region, so verify with your facility and plan.
Average Appendectomy Cost
According to Healthcare Bluebook, the fair price for a laparoscopic appendectomy sits in the low-to-mid five figures — a useful benchmark that represents what an informed patient with bargaining power should expect to pay, though it is an estimate rather than a fixed rate. Actual hospital bills vary enormously based on clinical complexity and the facility’s pricing structure. Data from CMS and hospital price transparency disclosures show that appendectomy charges range from roughly $10,000 to $40,000 or more depending on the facility, geographic region, and whether the appendix has perforated before surgery. Since 2021, hospitals have been required to post their standard charges publicly, so it is increasingly possible to look up a specific facility’s posted rates for appendectomy-related codes.
A straightforward laparoscopic appendectomy with a one-night hospital stay falls at the lower end (roughly $10,000 to $18,000). This represents the “best case” scenario: a patient arrives at the ER with classic symptoms, gets diagnosed promptly via CT scan or clinical evaluation, goes to the operating room within hours, has an uncomplicated laparoscopic procedure, and is discharged the next morning.
A complicated case — perforated appendix with peritonitis, conversion from laparoscopic to open surgery, abscess requiring drainage, or a multi-day hospital stay with IV antibiotics — pushes costs to $25,000 to $40,000 or significantly higher. Emergency room fees alone add roughly $1,500 to $5,000 to the bill before the surgery even begins. These ER fees include the facility charge, physician evaluation, IV fluids, pain management, and monitoring — all of which are billed separately from the surgical procedure.
Appendectomy Cost With Insurance vs. Without Insurance
Appendectomy is classified as medically necessary and is an emergency procedure, so insurance coverage is essentially universal. The challenge is managing costs when you’re in an emergency situation and can’t choose your facility, surgeon, or anesthesiologist in advance.
Without Insurance
Uninsured patients face billed charges of roughly $10,000 to $40,000 or more at full chargemaster rates. However, hospitals are generally required to offer financial assistance policies, and most provide self-pay discounts — often in the range of 30% to 60% — for uninsured patients who apply. Nonprofit hospitals receiving federal tax exemptions are required under the Affordable Care Act to maintain financial assistance (charity care) programs with defined eligibility criteria.
After discounts and financial assistance, uninsured patients typically pay somewhere in the range of $5,000 to $20,000 depending on case complexity, though outcomes vary. Payment plans are almost always available for emergency surgery — hospitals understand that patients who need emergency appendectomies couldn’t have planned or budgeted for the expense. Many hospitals offer interest-free payment plans extending 12 to 24 months, and some will negotiate further reductions for patients who can pay a lump sum. Requesting an itemized bill is critical — billing errors are common, and identifying duplicate charges or incorrect codes can reduce the total significantly.
If you are uninsured or self-pay, you also have the right to request a Good Faith Estimate under the No Surprises Act. For a true emergency this often arrives after the fact, but for any planned follow-up care (imaging, a scheduled interval appendectomy, or wound care) you can ask for a written estimate in advance and use it to question a final bill that comes in much higher.
With Insurance
Your out-of-pocket cost depends on your plan’s deductible, coinsurance, and out-of-pocket maximum. For a $20,000 appendectomy, a patient with a $2,000 deductible and 20% coinsurance would owe roughly $5,600 — but if their out-of-pocket maximum is $6,000, costs are capped there. Many patients reach their out-of-pocket maximum with an appendectomy, especially when ER fees, surgeon charges, anesthesiologist charges, hospital stay, pathology, and laboratory fees are combined. Under the Affordable Care Act, most plans have an annual out-of-pocket maximum that caps your total in-network cost-sharing for the year, so it is worth knowing your plan’s number before the bills arrive.
The No Surprises Act (in effect since January 2022) protects patients from out-of-network balance billing for emergency services, which is particularly important for appendectomy since you can’t control which ER you end up at or which surgeons and anesthesiologists are on call. Under this law, you’re generally responsible only for in-network cost-sharing amounts even if the hospital or individual providers (surgeon, anesthesiologist, radiologist, pathologist) are out of your insurance network. This protection is automatic — you don’t need to invoke it, though you should still review your bills to make sure it was applied.
Medicare covers appendectomy under Part A (hospital stay) and Part B (surgeon and anesthesiologist fees). For 2026, the Part A inpatient hospital deductible is $1,736 per benefit period, and Part B carries 20% coinsurance after the annual Part B deductible of $283. With Medigap supplemental coverage, out-of-pocket costs may be minimal. Medicare Advantage plans have varying cost structures but are subject to annual out-of-pocket maximums that cap your total exposure. Always confirm current figures, since Medicare cost-sharing amounts are updated each year.
Laparoscopic vs. Open Appendectomy Costs
Laparoscopic appendectomy has become the standard of care, accounting for roughly 80% to 85% of all appendectomies performed in the US. It uses three to four small incisions (each about 5 to 12 mm), a camera (laparoscope), and specialized instruments to remove the appendix. The procedure typically takes 30 to 60 minutes, and most patients go home within about 24 hours. Estimated total cost: $10,000 to $20,000. Recovery: most patients return to normal activities in 1 to 3 weeks.
Open appendectomy, performed through a single larger incision (about 2 to 4 inches) in the right lower abdomen, is generally reserved for complicated cases: perforated appendix with widespread infection, appendiceal abscess requiring drainage, conversion from a laparoscopic approach (when anatomy is unclear or complications arise during the laparoscopic procedure), or suspected appendiceal tumor requiring wider excision. Hospital stays are longer (about 2 to 5 days), recovery is slower (4 to 6 weeks for full activity), and the estimated total cost is higher: $15,000 to $35,000 or more.
The surgeon determines which approach to use based on clinical findings — patients don’t typically have a choice. However, hospitals with more experienced laparoscopic surgeons tend to have lower conversion-to-open rates, which can indirectly affect your cost. If you’re in a non-emergency situation (rare, but possible with early appendicitis identified incidentally), choosing a hospital with strong minimally invasive surgery capabilities can make a difference.
What Makes an Appendectomy More Expensive?
Perforation is the single biggest cost multiplier. A perforated appendix with peritonitis (infection spreading beyond the appendix into the abdominal cavity) may require open surgery, peritoneal washout (irrigating the abdominal cavity), drainage procedures, IV antibiotics for several days, and a hospital stay of 3 to 7 days or longer. The total bill can double or triple compared to an uncomplicated case — reaching an estimated $30,000 to $60,000 before insurance.
According to research published in the Annals of Surgery and other surgical literature, perforation occurs in roughly 20% to 30% of appendicitis cases, with higher rates in young children, adults over 65, and patients who delay seeking care. This is the strongest argument against “waiting to see if it gets better” — every hour of delay can increase perforation risk, and perforation dramatically increases both medical risk and financial cost.
Hospital location and type matter, though emergency situations limit your ability to choose. Appendectomies at large academic medical centers and urban teaching hospitals generally cost more than at community hospitals. ER fees vary dramatically — from around $1,500 at a community ER to $5,000 or more at a major trauma center. Pre-operative imaging (a CT scan or ultrasound) adds roughly $300 to $2,000 depending on the facility and imaging protocol. Post-operative complications — wound infection, abscess formation, ileus (temporary bowel dysfunction), or readmission — each add substantial cost.
How to Manage Appendectomy Costs
Unlike elective procedures, you can’t shop around for an appendectomy or schedule it at the most cost-effective facility. But there are meaningful steps to manage costs both during and after the event.
Review your hospital bill carefully once you receive it. Billing errors are common, so request an itemized bill (not just a summary) and look for duplicate charges, incorrect procedure codes, charges for services you didn’t receive, and charges for supplies that were opened but not used. If you find discrepancies, contact the hospital billing department to dispute them, in writing when possible.
Compare charges against fair-price benchmarks on Healthcare Bluebook, the hospital’s own posted price transparency file, or Medicare’s published payment rates. If your bill seems significantly inflated beyond these benchmarks, negotiate with the hospital’s billing department. For insured patients, your insurance company has already negotiated rates — but verify that those negotiated rates were applied correctly to your bill and that any No Surprises Act protections were honored.
Uninsured patients should immediately ask about financial assistance programs and charity care. Many hospitals will reduce bills substantially — often 40% to 70% — for patients who qualify based on income. The application process requires documentation (tax returns, pay stubs, bank statements) but is usually straightforward. Don’t ignore the bill or assume it’s non-negotiable — hospitals expect uninsured patients to negotiate and have systems in place to accommodate reduced payments. A nonprofit patient advocate or medical billing advocate can help with larger or disputed bills.
If you have a high-deductible health plan and the appendectomy hits early in the year (before you’ve met your deductible), your out-of-pocket costs may be substantial. The silver lining: you’ve likely met your deductible and possibly your out-of-pocket maximum for the remainder of the calendar year, making any additional in-network care significantly cheaper. If it is medically appropriate, that can be a sensible time to schedule other care your doctor has recommended — for example a colonoscopy or an MRI — within the same calendar year while you’ve already met your cost-sharing obligations.
Frequently Asked Questions
Does insurance cover an appendectomy?
Yes. Appendectomy is a medically necessary emergency procedure covered by health insurance plans, Medicare, and Medicaid. You’re responsible for your plan’s cost-sharing (deductible, copays, coinsurance) up to your out-of-pocket maximum. The No Surprises Act protects you from out-of-network balance billing for emergency services, regardless of which hospital or providers treat you.
How much does an appendectomy cost with Medicare?
Under Original Medicare in 2026, you pay the Part A hospital deductible of $1,736 for the inpatient stay (per benefit period). Part B covers the surgeon and anesthesiologist at 80%, with you owing 20% coinsurance after the Part B deductible of $283. With Medigap supplemental coverage (especially Plan G), out-of-pocket costs may be very low. Medicare Advantage plans have varying copays and out-of-pocket maximums that cap your total appendectomy cost. Confirm current amounts, as they change annually.
Can appendicitis be treated without surgery?
In select cases of uncomplicated appendicitis (no perforation, no abscess, no fecalith), antibiotics alone may be effective. Research published in the New England Journal of Medicine has shown antibiotic-only treatment can resolve a majority of uncomplicated cases in the short term. However, a meaningful share of antibiotic-treated patients ultimately need surgery within a few years due to recurrence. Many US surgeons still recommend appendectomy as the definitive treatment because it eliminates the risk of recurrence and perforation. This is a decision to make with your surgeon based on your specific case.
How long is the hospital stay for an appendectomy?
Uncomplicated laparoscopic appendectomy typically requires a one-night hospital stay, with some patients discharged the same day at facilities with outpatient appendectomy protocols. Complicated cases (perforation, abscess, peritonitis) may require 3 to 7 days of hospitalization for IV antibiotics, wound management, and monitoring. Each additional hospital day can add roughly $2,000 to $5,000 to the total bill.
Should I delay surgery to save money?
No. Delaying treatment for suspected appendicitis increases the risk of perforation, which is more dangerous and far more expensive to treat. If you have symptoms of appendicitis, seek emergency care promptly. Cost management comes after the emergency, through the steps outlined above.
The Bottom Line
As of early 2026, an appendectomy costs an estimated $10,000 to $35,000 depending on complexity and hospital, but as an emergency procedure, you can’t control the timing, facility, or providers — and you should never delay care over cost. Focus on what you can control: review your bill line by line for errors, negotiate if you’re uninsured, apply for financial assistance if you qualify, use the No Surprises Act and Good Faith Estimate protections, and leverage the fact that a large hospital bill likely satisfies your annual deductible. If you’re experiencing symptoms of appendicitis, go to the ER — a perforated appendix is far more expensive (and far more dangerous) to treat than an uncomplicated one caught early.
