Appendectomy is the surgical removal of the appendix, performed emergently or urgently in roughly 300,000 cases per year in the United States. Laparoscopic appendectomy (minimally invasive, three small incisions) now accounts for approximately 90 percent of all cases and typically results in a one-night hospital stay. Open appendectomy (a single larger incision) is reserved for complex presentations, prior abdominal surgery, or cases where the laparoscopic approach is not feasible. Both approaches carry similar total costs for uncomplicated appendicitis. The procedure is coded as CPT 44970 for laparoscopic and CPT 44950 for open; these are AMA-licensed CPT codes with no public-domain HCPCS Level II equivalent.
The cost of an appendectomy without insurance in 2026 spans a very wide range because the total bill typically includes multiple separate charges: the emergency room visit and evaluation, the facility fee for the operating room, the surgeon's professional fee, the anesthesiologist's fee, pathology for the removed specimen, and the inpatient room-and-board charge if the patient stays overnight. Each of these components can arrive as a separate bill from a separate provider. Patients who identify as self-pay or uninsured before or after the procedure have specific rights under federal law including the right to a written itemized bill and, for scheduled procedures, a written Good Faith Estimate. Patients can also negotiate bills after the fact, with hospitals routinely offering 30 to 50 percent reductions for prompt cash payment.
This guide covers what an appendectomy costs without insurance in 2026, what Medicare pays under both Part A (hospital) and Part B (surgeon), how the laparoscopic versus open versus complicated (perforated) distinction drives cost, and how to request a Good Faith Estimate or negotiate a hospital bill. The 2026 Medicare Part A and Part B deductibles and premium amounts are published by CMS at cms.gov, and the No Surprises Act consumer guidance is available at healthcare.gov.
Appendectomy Cost by Site of Service in 2026
The biggest cost driver of Appendectomy 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.
Appendectomy prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Inpatient hospital (standard admission, laparoscopic) | $9,000 to $22,000 | $1,736 Part A deductible (beneficiary share, days 1 to 60) |
| Ambulatory surgery center (ASC, elective uncomplicated laparoscopic) | $7,500 to $14,000 | ASC facility rate (approx. $2,800 to $4,200 for facility component) |
| Inpatient hospital (perforated appendix, complex or open surgery) | $20,000 to $60,000 | $1,736 Part A deductible; coinsurance begins day 61 |
| Emergency room evaluation only (pre-surgical workup, not operated) | $1,500 to $5,000 | Part B: 20% coinsurance after $283 deductible |
2026 Medicare rates reflect the Part A inpatient deductible of $1,736 for days 1 to 60 per benefit period (CMS 2026). ASC facility rates are estimated from CMS 2026 ASC Payment System addenda. Without-insurance cash price ranges reflect FAIR Health Consumer, CMS Hospital Price Transparency data, and KFF Health System Tracker analysis for 2025 to 2026. Surgeon professional fee (approx. $950 under 2026 PFS) is billed separately on top of facility rates.

Why the Same Procedure Is So Much More at a Hospital
The 2026 appendectomy cost chart shows a substantial range across settings. Hospital inpatient billing for appendectomy includes the facility fee (operating room, nursing, equipment), room-and-board, anesthesia, and pathology, all rolled into a single DRG-based payment under Medicare but billed as separate line items to uninsured patients. Ambulatory surgery centers are only feasible for elective or interval appendectomies, where the acute phase has resolved and the surgeon schedules the procedure in advance. Most emergency appendectomies go directly to the hospital operating room, bypassing the ASC option entirely. For those cases, the chargemaster facility fee from a hospital outpatient or inpatient department is typically 2 to 3 times higher than an ASC for comparable surgical complexity.
Hospital billing for emergency surgery also reflects the emergency department evaluation charge, which is separate from the surgical facility fee. Patients frequently receive three to five separate bills: one from the hospital (facility), one from the surgeon, one from the anesthesiologist, one from the pathologist (appendix specimen), and sometimes one from the radiologist (CT scan used to confirm diagnosis). Uninsured patients can request an itemized statement of all charges and, for any scheduled or elective component, a written Good Faith Estimate. For bills already received, hospitals are legally required to provide a plain-language explanation of charges and must maintain a charity care policy for patients meeting income thresholds.
For patients who had emergency surgery without any advance scheduling, the Good Faith Estimate requirement under the No Surprises Act does not apply to the emergency encounter itself. However, any follow-up care, drain placements, or additional scheduled procedures after the initial emergency encounter are subject to GFE requirements. Patients in this situation should ask the hospital's financial counselor about charity care eligibility, self-pay discounts, and interest-free payment plans before the first bill becomes a collection issue.
Appendectomy Cost by Procedure Type and Complexity in 2026
The biggest cost determinant for an appendectomy in 2026 is not where you live but rather what happens to the appendix before surgery. An uncomplicated laparoscopic appendectomy for a simple, non-perforated appendix is a one-night stay and a $15,000 average total bill. A perforated appendix requiring open surgery, IV antibiotics, and a 5 to 10-day admission can cost $30,000 to $60,000 or more. The table below captures the primary cost scenarios patients encounter in 2026.
Typical cost by variant| Procedure Type | Typical Setting | Cash Price Range (2026) | Avg Hospital Stay |
|---|
| Laparoscopic, uncomplicated | Hospital inpatient (1 night) or ASC | $9,000 to $22,000 | 1 night |
| Open appendectomy, uncomplicated | Hospital inpatient | $12,000 to $28,000 | 2 to 3 nights |
| Perforated appendix, laparoscopic or open | Hospital inpatient | $25,000 to $60,000+ | 5 to 10 nights |
| Elective/interval appendectomy (planned in advance) | ASC or hospital outpatient | $7,500 to $14,000 | Outpatient or 1 night |
Price ranges reflect total all-in cash costs including ER evaluation, facility, surgeon, anesthesia, and pathology, sourced from FAIR Health Consumer and CMS Hospital Price Transparency data for 2025 to 2026. Actual costs vary by geographic region (Northeast and California markets average 15 to 25 percent above national median), hospital type (academic medical center vs. community hospital), and specific complications encountered.

What Medicare Pays for Appendectomy
Medicare covers appendectomy as a medically necessary surgical procedure. For most beneficiaries admitted as hospital inpatients (which is the standard pathway for emergency appendectomy), Original Medicare Part A covers the facility cost under the Inpatient Prospective Payment System (IPPS). The beneficiary pays the 2026 Part A inpatient hospital deductible of $1,736, which covers days 1 through 60 of a single benefit period. There is no per-day coinsurance for days 1 through 60. Medicare pays the hospital a bundled DRG-based amount for uncomplicated appendectomy (DRG 341 to 343, depending on whether complications are present), which covers the operating room, nursing, anesthesia, pathology, and room-and-board as a single bundled facility payment.
The surgeon's professional fee for an appendectomy is billed separately under Medicare Part B, not Part A. Under the 2026 Medicare Physician Fee Schedule, laparoscopic appendectomy (CPT 44970) reimburses approximately $950 for the surgeon's professional component. The beneficiary owes 20 percent coinsurance after meeting the 2026 Part B deductible of $283. Medicare Advantage plans cover appendectomy in the same way as Original Medicare but may have different cost-sharing structures; beneficiaries should review the plan's Summary of Benefits and verify that the hospital and surgeon are in-network before any planned procedure. Medigap supplemental policies cover the Part A deductible and most or all of the Part B coinsurance, reducing out-of-pocket exposure to near zero for most appendectomy cases.
Commercial insurance (ACA-compliant plan, employer plan, or marketplace plan) covers appendectomy as a medically necessary surgical procedure subject to the plan's deductible, coinsurance, and out-of-pocket maximum. Most commercial plans have in-network deductibles of $1,000 to $3,000 for an individual and an out-of-pocket maximum of $4,000 to $9,450 (the 2026 ACA out-of-pocket cap for self-only coverage is $9,200). High-deductible health plan (HDHP) members who have not yet met their deductible will owe the full deductible amount first, which can mean $1,500 to $3,000 due before insurance begins covering anything. Prior authorization is typically not required for emergency appendectomy, but any follow-up procedures or elective interval appendectomy may require prior authorization under commercial and Medicare Advantage plans. For out-of-network providers, the No Surprises Act limits balance billing to in-network cost-sharing amounts for emergency services, so an unplanned emergency appendectomy at an out-of-network facility does not expose the patient to unlimited balance bills.
The No Surprises Act, which took effect January 1, 2022, provides two distinct layers of protection for appendectomy patients. First, for emergency services: providers cannot charge out-of-network patients more than in-network cost-sharing amounts, and balance billing above the in-network rate is prohibited for emergency surgery, including emergency appendectomy. Second, for any scheduled or elective appendectomy (such as an interval appendectomy planned days or weeks after an initial conservative antibiotic treatment): self-pay and uninsured patients are entitled to a written Good Faith Estimate at least 3 business days before the scheduled service, provided the appointment is scheduled at least 10 business days out, or at least 1 business day before service if scheduled 3 to 9 business days out. The federal consumer guidance and dispute portal is at cms.gov/nosurprisesact.
To request a Good Faith Estimate for a scheduled appendectomy or any related follow-up surgical procedure in 2026, patients should follow these steps: (1) Contact the hospital, surgical center, or surgeon's office before the procedure date and identify yourself as self-pay or uninsured. (2) Ask for a written Good Faith Estimate that includes the facility fee, surgeon fee, anesthesiologist fee, expected pathology charge, and any anticipated imaging or lab fees, with the specific CPT or procedure codes listed. (3) Provide your ZIP code and note any expected add-ons such as drain placement, wound irrigation, or extended recovery room time. (4) Confirm the timing: the GFE must arrive at least 3 business days before a service scheduled 10 or more business days out, or at least 1 business day before a service scheduled 3 to 9 business days out. (5) Keep the written GFE. If the final bill exceeds the GFE by $400 or more, you have the right to file a patient-provider dispute resolution (PPDR) claim within 120 days of the bill date through the federal portal at cms.gov/nosurprisesact.
A Good Faith Estimate for a scheduled appendectomy or related surgical procedure is not a guaranteed final bill. Common reasons the actual charges exceed the estimate include: conversion from laparoscopic to open surgery during the procedure, unexpected findings requiring additional operative steps (abscess drainage, bowel resection), longer-than-anticipated anesthesia time billed at a per-minute rate, recovery room or ICU time beyond the standard estimate, the anesthesiologist being a different provider than initially planned, and individual polyp or specimen handling charges not included in the surgical 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 a patient-provider dispute resolution claim at the federal portal at cms.gov/nosurprisesact.
What Factors Affect Cost
- Laparoscopic vs. open vs. perforated appendix: uncomplicated laparoscopic averages $15,000 total in 2026; a perforated appendix requiring extended hospitalization can reach $60,000 or more.
- Site of service: ambulatory surgery centers for elective interval appendectomies bill facility fees approximately 30 to 50 percent below hospital outpatient rates for comparable complexity. Emergency presentations have no site-of-service choice.
- Independent cash-pay bundles at surgical centers: some ambulatory surgery centers and surgical hospitals publish flat-rate self-pay bundles for elective laparoscopic appendectomy of $7,500 to $12,000 inclusive of surgeon, anesthesia, and facility. Always ask for the written bundled cash price before scheduling.
- Hospital chargemaster discount ask: most hospitals publish a self-pay discount policy of 20 to 60 percent off the chargemaster rate. Some hospitals apply this discount automatically when the patient identifies as uninsured; others require an explicit written request. For a $25,000 chargemaster appendectomy bill, a 40 percent self-pay discount reduces the balance to $15,000 before any further negotiation.
- Sliding-scale Federally Qualified Health Centers (FQHCs): FQHCs provide primary care and preventive services on a sliding-scale fee basis tied to household income and Federal Poverty Level thresholds. Appendectomy surgery itself is not performed at FQHCs (they do not have operating rooms), but pre-operative evaluation and post-operative follow-up can be handled at FQHC rates. If income qualifies, linking the patient to a Medicaid enrollment path through an FQHC navigator may cover the appendectomy retroactively in Medicaid expansion states.
- Anesthesia billing model: anesthesiologists bill separately from the surgeon and facility. An anesthesiologist who is out-of-network from the hospital can trigger a large surprise bill on emergency cases. The No Surprises Act bars out-of-network balance billing for emergency services starting January 2022, capping the patient's share at in-network cost-sharing levels. Verify that the anesthesiologist is in-network for any planned surgery.
- Post-operative imaging and drain management: patients with complicated appendicitis may require follow-up CT scans, drain tube management, or interventional radiology procedures after the initial surgery, each of which generates an additional bill. These follow-up services are typically scheduled in advance and are subject to the Good Faith Estimate requirement under the No Surprises Act.
- Prior authorization for elective procedures: commercial insurers and Medicare Advantage plans typically do not require prior authorization for emergency appendectomy because it is an acute condition. However, an interval or elective appendectomy scheduled days or weeks later may require pre-authorization. Failure to obtain prior auth before an elective appendectomy can result in the full cost being shifted to the patient as an out-of-pocket expense.
Common Appendectomy Billing Errors
Appendectomy bills are among the most complex in U.S. emergency surgery because multiple providers bill separately, the procedure frequently has unexpected complications, and uninsured patients often do not know which charges to dispute. Check for these billing errors before paying any appendectomy bill in 2026:
- Duplicate facility charges from both the emergency department and the inpatient surgical admission. The ER visit and the surgical admission should be two separate claims, but some hospitals erroneously bill both a full ER facility fee and a full inpatient facility fee covering overlapping hours.
- Anesthesiologist billed at out-of-network rates when the hospital is in-network. Under the No Surprises Act, the patient's cost-sharing cannot exceed in-network levels for emergency surgery anesthesia. If you received a balance bill from an out-of-network anesthesiologist for emergency appendectomy, dispute it citing the No Surprises Act.
- Pathology charge billed as a full complex specimen analysis when a routine gross and microscopic examination was appropriate for a non-perforated appendix.
- Hospital chargemaster rate applied without offering the published self-pay or uninsured discount. Ask the billing department explicitly: 'What is the self-pay discount rate, and does it apply to my account?'
- CT scan for diagnostic workup billed separately at the full radiologist professional fee when the CT interpretation was already bundled in the emergency department evaluation and management charge.
- Inpatient DRG billing for a patient who was only held for observation status, not formally admitted. Observation status is billed under Part B, not Part A, which means the patient owes the Part B deductible and 20 percent coinsurance, not the Part A deductible, and SNF coverage does not follow. Request confirmation of your admission status in writing.
Frequently Asked Questions
How much does an appendectomy cost without insurance in 2026?
Without insurance in 2026, an appendectomy typically costs $7,500 to $35,000 depending on whether the procedure is laparoscopic or open and whether the appendix has ruptured. The national average for an uncomplicated laparoscopic procedure, including the ER visit, facility, surgeon, anesthesia, and pathology, is approximately $15,000. A perforated appendix requiring multiple days in the hospital can reach $30,000 to $60,000. Most hospitals offer a self-pay discount of 20 to 50 percent off the chargemaster rate if you identify as uninsured or request it in writing.
What does Medicare pay for an appendectomy in 2026?
Medicare covers appendectomy under two separate parts. Part A covers the hospital facility and inpatient stay. The Medicare beneficiary pays the 2026 Part A deductible of $1,736, which covers days 1 through 60 of the hospital admission. Medicare then pays the rest of the DRG-based facility amount directly to the hospital. Part B covers the surgeon's professional fee separately; under the 2026 Medicare Physician Fee Schedule, laparoscopic appendectomy reimburses approximately $950 for the surgeon, and the beneficiary owes 20 percent coinsurance after the 2026 Part B deductible of $283. Medigap plans typically cover both the Part A deductible and the Part B coinsurance, reducing total out-of-pocket to near zero.
How do I request a Good Faith Estimate for a scheduled appendectomy?
For any scheduled appendectomy or planned follow-up surgical procedure, self-pay and uninsured patients have the right to a written Good Faith Estimate under the No Surprises Act. Call the hospital or surgical center before the procedure date and identify yourself as self-pay or uninsured. Ask for a written Good Faith Estimate that itemizes the facility fee, surgeon fee, anesthesiologist fee, and pathology charge with procedure codes. If the appointment is 10 or more business days out, the estimate must arrive at least 3 business days before service. If scheduled 3 to 9 business days out, the estimate must arrive at least 1 business day before. Keep the estimate: if the final bill exceeds it by $400 or more, you can file a dispute within 120 days at cms.gov/nosurprisesact.
Does the No Surprises Act apply to emergency appendectomy?
The No Surprises Act provides two protections relevant to emergency appendectomy. First, for the emergency encounter itself, providers at out-of-network facilities cannot charge you more than in-network cost-sharing amounts, and balance billing above the in-network rate is prohibited. This means that even if you arrived at an out-of-network hospital by ambulance, your share of the appendectomy cost is capped at what you would owe in-network. Second, the advance Good Faith Estimate requirement does not apply to true emergency services because there is no opportunity to schedule them in advance. However, any planned follow-up procedures after the emergency admission are subject to the GFE requirement. The CMS consumer portal is at cms.gov/nosurprisesact.
How do I get a written cash-pay quote for an appendectomy?
For a planned or elective appendectomy, call the surgical center or hospital's financial counseling or patient access department and ask for the bundled self-pay or cash-pay price. A good question to ask is: 'What is the all-in cash price for a laparoscopic appendectomy including the facility fee, anesthesia, and surgeon fee?' Get the quote in writing as a Good Faith Estimate. Some ambulatory surgery centers publish flat-rate self-pay bundles of $7,500 to $12,000 for elective laparoscopic appendectomy. Hospital rates for the same procedure are typically 30 to 70 percent higher than ASC cash rates. Compare the written cash price to your insurance's negotiated rate before deciding which to use.
Can I negotiate an appendectomy bill after the fact?
Yes. Even after receiving a hospital bill for an appendectomy, you have strong negotiating leverage. Hospitals routinely reduce bills by 30 to 50 percent for patients who offer prompt cash payment on the outstanding balance. Start by requesting an itemized statement of all charges and checking for billing errors (duplicate charges, incorrect observation vs. admission status, out-of-network anesthesia that should be capped under the No Surprises Act). Ask the hospital's financial counselor about charity care eligibility, which covers patients below 200 to 400 percent of the Federal Poverty Level at many hospitals. If the bill exceeds your Good Faith Estimate by $400 or more, you can file a patient-provider dispute resolution claim at cms.gov/nosurprisesact within 120 days of the bill date.
What is the difference between hospital and ASC appendectomy cost in 2026?
For the small share of appendectomies that can be performed at an ambulatory surgery center (ASC), the cost difference in 2026 is substantial. An elective laparoscopic appendectomy at an ASC typically costs $7,500 to $14,000 all-in, compared to $9,000 to $22,000 at a hospital inpatient setting for a comparable uncomplicated case. The ASC saving comes from lower facility overhead and a more streamlined surgical model. The catch is that most appendectomies are emergencies presenting through the ER, which routes patients directly to hospital admission with no ASC option. Interval or elective appendectomies (planned days to weeks after initial antibiotic treatment) are the cases where an ASC setting is feasible and worth comparing.
Will my insurance cover an appendectomy in 2026?
Yes, appendectomy is covered as a medically necessary surgical procedure by virtually all commercial health insurance plans, ACA-compliant marketplace plans, and Medicare. The patient's share depends on the plan's deductible, coinsurance, and out-of-pocket maximum. On a typical employer plan with a $1,500 deductible and 20 percent coinsurance up to an $8,000 out-of-pocket maximum, the patient would pay roughly $1,500 to $3,000 for an uncomplicated laparoscopic appendectomy. High-deductible health plan members may owe the full deductible ($1,500 to $3,500 for self-only coverage in 2026) before insurance begins covering costs. Emergency appendectomy does not require prior authorization under most plans.
What is the difference between a laparoscopic and open appendectomy in terms of cost?
Laparoscopic appendectomy (CPT 44970) uses three small incisions and a camera, typically results in a one-night hospital stay, and averages $9,000 to $22,000 total without insurance in 2026. Open appendectomy (CPT 44950) uses a single larger incision and is typically reserved for perforated appendix, obesity, or prior abdominal surgery; it usually requires a two to three-night stay and costs $12,000 to $28,000. The laparoscopic approach is the standard choice because it reduces recovery time and post-surgical complications, which lowers the total episode cost even if operating room time is slightly longer. Both are covered equally by Medicare and commercial insurance as medically necessary surgical procedures.
What happens to my appendectomy bill if I was taken to an out-of-network hospital?
Under the No Surprises Act, if you received emergency care at an out-of-network hospital for appendectomy, the hospital and all providers who treated you there can only charge you the in-network cost-sharing amount for your plan (deductible plus coinsurance up to your out-of-pocket max), not the full out-of-network rate. Balance billing above the in-network cost-sharing level is prohibited for emergency services. If you received a bill charging more than your in-network cost-sharing would require, contact your insurance plan and cite the No Surprises Act. If you are uninsured, the hospital's self-pay discount policy and charity care program apply. For any insured or uninsured dispute, the federal portal at cms.gov/nosurprisesact provides consumer guidance and a dispute resolution mechanism.
