An upper endoscopy, formally called esophagogastroduodenoscopy or EGD, is a procedure in which a gastroenterologist passes a thin, flexible camera through the mouth to examine the esophagus, stomach, and first portion of the small intestine (the duodenum). Doctors order it to investigate persistent heartburn that does not respond to medication, difficulty swallowing, unexplained weight loss, suspected ulcers, possible celiac disease, or upper GI bleeding. About 7 million upper endoscopies are performed in the United States each year.
Upper endoscopy is not a USPSTF preventive service for the general population. Unlike colorectal cancer screening colonoscopy, there is no USPSTF Grade A or B recommendation for routine EGD screening in asymptomatic adults. That means ACA plans are not required to cover it at zero cost-sharing as a preventive benefit. Coverage and patient cost-sharing are determined by each plan and depend on the specific diagnostic indication your physician documents. For a lower GI scope, compare the colonoscopy cost guide.
This guide covers what an upper endoscopy costs without insurance in 2026, what Medicare pays, why the same EGD costs more than twice as much at a hospital than at an ASC, and how to avoid the anesthesia surprise-billing trap that catches patients off guard after the procedure. Patients who cannot afford the deductible on their current plan can check Medicaid income limits to see if they qualify for near-zero cost coverage.
Upper Endoscopy Cost by Site of Service in 2026
The biggest cost driver of Upper Endoscopy 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.
Upper Endoscopy prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Ambulatory surgery center (ASC) | $1,200 to $2,500 | $420 facility + ~$111 physician |
| Hospital outpatient department | $2,500 to $5,500 | $650 to $950 facility + ~$111 physician |
| GI office-based endoscopy suite | $1,400 to $2,800 | ~$322 (non-facility PFS rate, no separate facility fee) |
| Inpatient hospital (during admission) | $3,500 to $8,000+ | Bundled in DRG |
2026 Medicare facility rates: ASC ~$420 (ASC payment system), Hospital OPPS ~$650-$950, based on CMS 2026 OPPS/ASC final rule. Physician professional fee billed separately (~$111 facility PFS rate, ~$322 non-facility PFS rate). Without-insurance ranges reflect CMS Hospital Price Transparency data and FAIR Health Consumer. Anesthesia is always billed separately.

Why the Same Procedure Is So Much More at a Hospital
When an upper endoscopy is performed at an ambulatory surgery center (ASC), Medicare pays the facility using the ASC payment system, approximately $420 for a diagnostic EGD in 2026. When the same procedure is done at a hospital outpatient department, Medicare pays the hospital under the Outpatient Prospective Payment System (OPPS), typically $650 to $950 for a diagnostic EGD. In both cases, the gastroenterologist bills separately under the Physician Fee Schedule (approximately $111 in a facility setting). The procedure itself is identical. Only the billing system and overhead allocation differ.
The site-of-service gap is amplified in cash-pay markets. An ASC that might bill Medicare $420 for the facility component can offer a self-pay patient a bundled all-in price of $1,200 to $1,800 including sedation. A hospital outpatient department that bills Medicare $800 in facility fees may charge a cash-pay patient $3,500 to $5,500 for the same scope. The difference exceeds $2,000 for procedures that typically take 10 to 20 minutes.
The practical takeaway: if your gastroenterologist has privileges at both an ASC and a hospital outpatient department, ask to schedule at the ASC. You will likely save $1,500 to $3,000. Before scheduling, ask: Is this an ASC or a hospital outpatient department? Is the anesthesiologist in-network? Will pathology be billed separately and, if so, which lab?
Upper Endoscopy Cost by Indication and Complexity
A diagnostic EGD to evaluate heartburn or nausea is the simplest and least expensive version. If the gastroenterologist performs a biopsy, removes a polyp, dilates a stricture, or treats a bleeding vessel during the same session, a more complex billing code applies and the cost increases. These codes are additive: when a biopsy is taken during a diagnostic EGD, only the biopsy code (which includes the EGD) is billed, not both.
Typical cost by variant| Procedure Type | What It Involves | Cash Range (ASC) | Cash Range (Hospital) |
|---|
| Diagnostic EGD (no intervention) | Visual inspection only | $1,200 to $2,000 | $2,500 to $4,500 |
| EGD with biopsy | Tissue sample taken for pathology | $1,400 to $2,400 | $2,800 to $5,000 |
| EGD with dilation (stricture) | Balloon or bougie dilation of narrowed area | $1,600 to $2,800 | $3,000 to $5,500 |
| Surveillance EGD for Barrett's esophagus | Mapping biopsies for Barrett's surveillance | $1,500 to $2,600 | $2,800 to $5,500 |
Pathology fees for biopsies are billed separately by the interpreting pathologist and can add $150 to $600. A surveillance EGD for Barrett's esophagus is a distinct indication from diagnostic EGD and carries its own coverage rules under some insurance plans.

What Medicare Pays for Upper Endoscopy
Medicare Part B covers upper endoscopy when a physician orders it for a medically necessary diagnostic indication such as persistent acid reflux that does not respond to proton pump inhibitors, dysphagia, unexplained iron-deficiency anemia, suspected peptic ulcer, or surveillance of known Barrett's esophagus. Coverage requires a documented clinical indication in the medical record. Your cost-sharing in 2026: 20% coinsurance after the Part B annual deductible of $283. The 2026 Part B monthly premium is $202.90. If you have a Medigap (Medicare Supplement) plan, it typically covers the 20% coinsurance.
In 2026, Medicare pays the gastroenterologist approximately $111 under the Physician Fee Schedule (facility setting rate) or approximately $322 in a non-facility office-based setting. The facility payment is separate: approximately $420 at an ASC or $650 to $950 at a hospital outpatient department. If a biopsy is performed, the pathologist bills separately under the PFS and Medicare applies the same 20% coinsurance to that charge as well. Medicare Advantage plans cover upper endoscopy for diagnostic indications, typically with prior authorization and copays of $75 to $300 per plan.
Your right to a Good Faith Estimate (GFE): Under the No Surprises Act, if you schedule an upper endoscopy and you are uninsured or paying out-of-pocket, the provider must give you a written GFE within 3 business days of scheduling. The GFE must separately itemize the gastroenterologist fee, facility fee, anesthesia fee, and any expected pathology charges. Request it in writing before your procedure date. If the provider refuses, that is a No Surprises Act violation you can report to CMS.
If your final bill exceeds the GFE amount by more than $400, you have 120 calendar days from receipt of the bill to initiate a Patient-Provider Dispute Resolution (PPDR) case through CMS. The PPDR process caps your liability at or near the GFE amount while the dispute is resolved. You do not need to pay the disputed amount while the case is open. For surprise bills from out-of-network providers at in-network facilities (the anesthesia trap described below), the No Surprises Act caps your cost at in-network cost-sharing.
What Factors Affect Cost
- Site of service: the single biggest cost driver. An ASC charges $1,200 to $2,500 for the same EGD a hospital outpatient department bills at $2,500 to $5,500.
- Whether a biopsy, dilation, or other intervention is performed during the same session. A biopsy adds a more complex code and typically $200 to $600 more in total cost.
- Anesthesia: propofol sedation administered by an anesthesiologist or CRNA is billed separately from the facility and gastroenterologist. This adds $300 to $800 and is the most common source of unexpected out-of-network charges. If the anesthesiologist is not in your plan's network but the facility is, the No Surprises Act limits your cost to in-network rates, but you must verify beforehand and dispute if billed improperly.
- Pathology: if biopsies are taken, the tissue is sent to a pathologist who bills independently. Pathology fees add $150 to $600 and may come from an out-of-network lab even when the gastroenterologist and facility are in-network.
- Self-pay vs. insured: many ASCs and GI practices offer bundled cash-pay rates of $1,200 to $1,800 that include facility, physician, and anesthesia. Always ask for the self-pay rate before the procedure. Hospitals may offer self-pay discounts of 20 to 50% off the chargemaster price, but you have to ask specifically.
- Geographic region: upper endoscopy costs vary significantly by market. Urban major-metro markets (New York, San Francisco, Los Angeles) can run 50 to 100% higher than rural markets. FAIR Health Consumer data shows a state-level range of $2,190 in Mississippi to $4,140 in Hawaii for the cash-pay price.
- Deductible status: if you have insurance and have not yet met your annual deductible, an upper endoscopy may cost you the full negotiated rate out-of-pocket, not just a copay.
- Barrett's esophagus surveillance vs. diagnostic EGD: surveillance EGDs for known Barrett's esophagus involve four-quadrant biopsy mapping every 1 to 2 centimeters, taking more time and requiring more pathology processing than a standard diagnostic EGD. Coverage and cost-sharing may differ by plan.
Common Upper Endoscopy Billing Errors
Upper endoscopy bills have several recurring error patterns. If your bill is higher than expected, check for these before paying:
- Anesthesiologist billed out-of-network at an in-network facility. This is the most common EGD surprise bill. The gastroenterologist and ASC may be in-network but the anesthesiologist contracted separately is not. Under the No Surprises Act, your liability is capped at your in-network cost-sharing. Dispute any balance bill exceeding that amount through your insurer's No Surprises Act process.
- Both the diagnostic EGD code and the biopsy code billed for the same session. When a biopsy is taken, only the biopsy code (which includes the endoscopy) should be billed. Billing both is improper unbundling and should be disputed.
- Hospital outpatient facility rate billed for a procedure performed at an affiliated ASC or GI center. If the procedure was performed at a location that is not the hospital's main campus but the bill uses hospital outpatient codes, the cost may be 2x what it should be. Verify the actual site address against the billing address.
- Pathology billed from an out-of-network lab. Tissue biopsies taken during the EGD are processed by a pathologist who may not be in your plan's network. Ask in advance which pathology lab will process your samples and whether that lab is in-network.
- Duplicate charge for the sedation drug (propofol) when anesthesia services are already billed. Some facilities bill propofol as a pharmacy line item in addition to the anesthesia professional fee. Only one of these should appear.
- Wrong procedure complexity code. If a diagnostic EGD (visual only) was performed but the bill shows a biopsy or intervention code, your cost-sharing increases unnecessarily. Compare what your doctor documented in the procedure report against the billing codes on the Explanation of Benefits.
Frequently Asked Questions
How much does an upper endoscopy (EGD) cost without insurance in 2026?
Without insurance in 2026, an upper endoscopy (EGD) costs $1,200 to $5,500. The national average is approximately $2,100. At an ambulatory surgery center the range is $1,200 to $2,500; at a hospital outpatient department the range is $2,500 to $5,500. Anesthesia and any biopsy pathology fees are billed separately and add $450 to $1,400 more.
What is an EGD and how is it different from an upper endoscopy?
EGD and upper endoscopy refer to the same procedure. EGD stands for esophagogastroduodenoscopy, the full medical term. Upper endoscopy is the common name. During the procedure, a gastroenterologist passes a thin flexible camera through your mouth to examine the esophagus, stomach, and duodenum (first section of the small intestine). The 15-to-20-minute procedure is performed under moderate sedation, typically with propofol.
Is upper endoscopy covered as a preventive service under the ACA?
No. Upper endoscopy is not a USPSTF preventive service for the general population. The ACA's zero-cost-sharing preventive benefit applies only to procedures with a USPSTF Grade A or B recommendation. There is no such USPSTF recommendation for routine EGD screening in asymptomatic adults. Your plan may still cover a diagnostic EGD, but it will apply your deductible and coinsurance rather than covering it at 100%.
How much does Medicare pay for an upper endoscopy in 2026?
In 2026, Medicare pays the gastroenterologist approximately $111 under the Physician Fee Schedule (facility setting) plus approximately $420 to the ASC or $650 to $950 to the hospital outpatient department. Your share as a Medicare patient: 20% coinsurance after meeting the 2026 Part B deductible of $283. If you have a Medigap plan it typically covers the 20%. Anesthesia is billed separately and subject to the same 20% coinsurance.
Why is upper endoscopy so much cheaper at an ASC than at a hospital?
The procedure is identical at both sites. The difference is in hospital overhead and billing structure. Hospital outpatient departments carry costs for emergency rooms, surgical suites, and general facility overhead, all of which are allocated into every bill. Ambulatory surgery centers specialize in outpatient procedures and operate with far lower overhead. In 2026, Medicare pays ASC facilities $420 versus $650 to $950 at hospital outpatient departments for the same EGD. Cash-pay prices follow a similar 2-to-3x ratio.
What is the anesthesia surprise-billing trap for upper endoscopy?
Moderate sedation with propofol for an upper endoscopy is administered by an anesthesiologist or CRNA who often bills independently from the facility and gastroenterologist. Even at an in-network facility with an in-network gastroenterologist, the anesthesia provider may be out-of-network, generating a surprise balance bill of $300 to $800. Under the No Surprises Act, if you are at an in-network facility and did not affirmatively choose an out-of-network anesthesiologist, your liability is capped at in-network cost-sharing. Dispute any balance bill above that amount through your insurer's No Surprises Act process.
What is the difference between a diagnostic EGD and surveillance endoscopy for Barrett's esophagus?
A diagnostic upper endoscopy evaluates a new symptom, such as heartburn, difficulty swallowing, or weight loss. A surveillance EGD for Barrett's esophagus is a follow-up procedure for a patient with previously diagnosed Barrett's, performed every 3 to 5 years (more frequently for high-grade dysplasia) to monitor for progression to esophageal cancer. Surveillance EGDs typically involve four-quadrant biopsies every 1 to 2 centimeters and take longer than a standard diagnostic EGD. Coverage and cost-sharing rules vary by insurer for the two indications.
How do I get a Good Faith Estimate before an upper endoscopy?
Under the No Surprises Act, if you are uninsured or self-pay, your provider must give you a written Good Faith Estimate (GFE) within 3 business days of scheduling. The GFE must separately list the gastroenterologist fee, facility fee, anesthesia fee, and expected pathology charges. Request it in writing when you call to schedule. If the total bill exceeds the GFE by more than $400, you have 120 days from receipt of the bill to open a dispute through CMS's Patient-Provider Dispute Resolution process.
Is upper endoscopy cheaper than a colonoscopy?
Generally yes, though both are performed by a gastroenterologist under sedation. An upper endoscopy typically costs $1,200 to $5,500 without insurance in 2026 versus $1,250 to $4,800 for a colonoscopy. The ranges overlap, but the upper range for colonoscopy is generally lower because colonoscopy has HCPCS codes enabling Medicare screening coverage, while upper endoscopy does not. ASC prices for both procedures are substantially lower than hospital outpatient prices. When both an upper endoscopy and colonoscopy are performed on the same day (a combined upper and lower GI evaluation), one procedure may be subject to a multiple-procedure reduction.
What self-pay options exist for upper endoscopy?
Several options exist. Many ASCs and GI practices offer bundled self-pay packages covering facility, physician, and anesthesia for $1,200 to $1,800 all-in. Ask the scheduling coordinator specifically for the self-pay or cash-pay rate. Programs like ColonoscopyAssist offer fixed rates around $1,275 for uninsured patients at participating centers. Some hospital systems offer charity care or financial assistance programs if your income is below a threshold. For Medicare patients, the 2026 Part B coinsurance of 20% after the $283 deductible applies to whatever the Medicare-approved amount is.
