Endoscopy describes any medical procedure that uses a thin, flexible camera to look inside the body without major surgery. In gastroenterology, the term covers four distinct procedures with different prices and Medicare coverage rules. Upper endoscopy, also called EGD, examines the esophagus, stomach, and duodenum through the mouth. Colonoscopy examines the full colon through the rectum. Flexible sigmoidoscopy examines only the lower colon and rectum, usually without sedation. Capsule endoscopy uses a swallowed pill-sized camera to image the small intestine. Roughly 7 million upper endoscopies and 15 million colonoscopies are performed in the United States each year.
The single biggest cost driver on an endoscopy bill is not the site of service, it is which procedure is performed and why. A screening colonoscopy or flexible sigmoidoscopy for an asymptomatic adult age 45 or older is covered at 100% under ACA-compliant plans and Original Medicare: no deductible, no copay, no coinsurance. An upper endoscopy or capsule endoscopy ordered for symptoms such as heartburn, bleeding, or weight loss almost always triggers your deductible and coinsurance, since there is no USPSTF preventive-care recommendation for those procedures in asymptomatic adults.
CoveredUSA's guide covers what an endoscopy costs without insurance in 2026 across all four common types, what Medicare pays for each, the Good Faith Estimate and No Surprises Act rights every self-pay patient has, and the billing errors that most often inflate an endoscopy bill. For a detailed breakdown of the two most common types, see the dedicated guides to upper endoscopy (EGD) cost and colonoscopy cost.
Endoscopy Cost by Site of Service in 2026
The biggest cost driver of 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.
Endoscopy prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Ambulatory surgery center (ASC) | $1,200 to $3,200 | $420 to $680 depending on procedure type |
| Hospital outpatient department | $2,500 to $7,500 | $650 to $1,260 depending on procedure type |
| GI office-based endoscopy suite | $500 to $3,000 | $53 to $322 non-facility PFS rate, varies by procedure |
| Inpatient hospital (during admission) | $3,500 to $8,000+ | Bundled in DRG |
2026 Medicare rates reflect the Physician Fee Schedule, ASC payment system, and Hospital OPPS for common diagnostic endoscopy codes and HCPCS G0104. Without-insurance ranges span all four endoscopy types and reflect CMS Hospital Price Transparency data and FAIR Health Consumer. Physician professional fees are billed separately from facility fees at ASC and hospital outpatient sites.

Why the Same Procedure Is So Much More at a Hospital
2026 endoscopy cost data from CMS Hospital Price Transparency and FAIR Health Consumer confirms a 2x to 3x billing differential between independent sites and hospital outpatient departments, and this holds across every endoscopy type. A screening flexible sigmoidoscopy performed in a physician's office with no sedation might cost $500 to $1,500 total. The same scope performed at a hospital outpatient department, even without sedation, is frequently billed at $1,500 to $3,000 because the hospital adds a facility fee on top of the physician fee.
Ambulatory surgery centers exist to perform endoscopic procedures at lower overhead than a hospital. Only the facility billing code changes; the physician, sedation, and equipment are identical. Under the 2026 Medicare Physician Fee Schedule and ASC payment system, an ASC facility fee for a typical diagnostic endoscopy runs $420 to $680, versus $650 to $1,260 under the Hospital OPPS, almost double for identical care. Ask your gastroenterologist whether they have privileges at an ASC as well as a hospital, and request the ASC. You will typically save $1,300 to $3,000 with no difference in safety.
Endoscopy Cost by Type in 2026
Endoscopy is not one procedure, it is a category. Each type below examines a different part of the digestive tract, uses different sedation, and carries different insurance coverage rules. Knowing which type your doctor ordered, and why, is the fastest way to estimate your real out-of-pocket cost.
Typical cost by variant| Type | What It Examines | Cash Price Range 2026 | ACA/Medicare Coverage |
|---|
| Upper endoscopy (EGD) | Esophagus, stomach, duodenum | $1,200 to $5,500 | Not a USPSTF preventive service; deductible and coinsurance apply |
| Colonoscopy | Full colon and rectum | $1,250 to $4,800 | Screening: $0 on ACA plans and Medicare; diagnostic has cost-sharing |
| Flexible sigmoidoscopy | Lower colon and rectum only | $500 to $1,500 | Screening: $0 on ACA plans and Medicare (HCPCS G0104) |
| Capsule endoscopy | Small intestine (swallowed camera) | $900 to $3,500 | Not a preventive service; typically requires prior authorization |
| Combined upper and lower endoscopy (same day) | Both EGD and colonoscopy in one session | $2,500 to $7,500 | Coverage follows the diagnostic or screening status of each component |
When two endoscopic procedures are performed in the same session, such as a combined upper and lower evaluation, a multiple-procedure payment reduction typically applies to the second procedure under Medicare and most commercial fee schedules. Capsule endoscopy Medicare payment is billed under a separate technical and professional interpretation component and often requires prior authorization on Medicare Advantage and commercial plans.

What Medicare Pays for Endoscopy
Original Medicare Part B covers endoscopic procedures differently depending on why they are ordered. Screening colonoscopy (HCPCS G0105 or G0121) and screening flexible sigmoidoscopy (HCPCS G0104) are covered at 100% with no Part B deductible, no coinsurance, and no age cap, for as long as a physician recommends screening. Upper endoscopy, capsule endoscopy, and diagnostic colonoscopy or sigmoidoscopy ordered for symptoms carry the standard 20% coinsurance after the 2026 Part B deductible of $283. Medicare Advantage plans must cover the same services but often add prior authorization, especially for capsule endoscopy. A Medigap policy typically pays the 20% coinsurance.
In 2026, the Medicare Physician Fee Schedule pays the gastroenterologist approximately $111 for a facility-based upper endoscopy, approximately $400 for a colonoscopy, and approximately $53 to $215 for a flexible sigmoidoscopy depending on setting. Facility payments are separate: an ASC typically receives $420 to $680 and a hospital outpatient department typically receives $650 to $1,260 for the same procedure. If a biopsy is taken, the pathologist bills separately and Medicare applies the same 20% coinsurance to that charge.
Commercial insurance and ACA-compliant plans handle endoscopy cost-sharing on the same screening-versus-diagnostic distinction as Medicare. On a high-deductible health plan (HDHP), a diagnostic upper endoscopy or capsule endoscopy applies to your full deductible before coinsurance kicks in, which can mean paying the full negotiated rate early in the plan year. Capsule endoscopy in particular often needs prior authorization on commercial and Medicare Advantage plans. In-network copay tiers for a specialist procedure like endoscopy commonly run $75 to $500.
The No Surprises Act, effective January 2022, gives every self-pay and uninsured patient the right to a written Good Faith Estimate before any scheduled endoscopy. For a procedure scheduled at least 10 business days out, the provider must furnish the Good Faith Estimate at least 3 business days before the service date. For an appointment scheduled 3 to 9 business days out, the estimate arrives at least 1 business day before service. The federal starting point for consumer guidance is cms.gov/nosurprisesact.
To request a Good Faith Estimate for an endoscopy in 2026, call the facility, identify yourself as self-pay or uninsured, and ask for a written estimate itemizing the physician fee, facility fee, and any anesthesia or pathology charges. Confirm the 3-business-day or 1-business-day timing rule based on your appointment date and keep the document. A final bill that exceeds the estimate by $400 or more can be disputed within 120 days at cms.gov/nosurprisesact.
A Good Faith Estimate for an endoscopy is not a guaranteed final bill. Common reasons the actual charge runs higher include a polyp or lesion found and removed, an unexpected biopsy sent to pathology, sedation running longer than expected, an additional procedure added during the same encounter, or supplies not in the original quote. Dispute any overage of $400 or more within 120 days at cms.gov/nosurprisesact.
What Factors Affect Cost
- Which type of endoscopy is performed: upper endoscopy, colonoscopy, flexible sigmoidoscopy, and capsule endoscopy have different price ranges and different Medicare coverage rules.
- Screening versus diagnostic billing classification, especially for colonoscopy and flexible sigmoidoscopy, which can shift the patient cost from $0 to over $1,500 for the identical procedure.
- Site of service (ASC vs hospital outpatient department vs office-based suite); hospital sites bill roughly 2x to 3x more for identical care under Medicare and cash-pay rates alike.
- Sedation type: monitored anesthesia care with propofol, billed separately by an anesthesiologist or CRNA, adds $300 to $800 and is the most common source of a surprise endoscopy bill. Flexible sigmoidoscopy usually needs no sedation at all.
- Independent ASC and GI practice cash bundles: many ambulatory surgery centers offer an all-inclusive self-pay rate covering the facility, physician, and anesthesia, typically 30 to 60 percent below the hospital chargemaster cash price.
- Hospital chargemaster discount ask: most hospitals publish a self-pay discount policy off the chargemaster, often 20 to 60 percent, but some apply it automatically and others require the patient to ask explicitly at scheduling.
- Sliding-scale FQHCs: federally qualified health centers offer endoscopy referrals or in-house screening with sliding-scale fees by household size and income, down to $0 for households under 100% of the federal poverty level.
- Prior authorization: capsule endoscopy and, less often, colonoscopy require prior authorization on many Medicare Advantage and commercial plans, and a denied authorization can shift the full cost to the patient if the procedure proceeds anyway.
Common Endoscopy Billing Errors
Endoscopy bills carry several recurring error patterns across all four procedure types. Check for these before paying:
- Screening colonoscopy or flexible sigmoidoscopy billed as diagnostic because intake paperwork mentioned a symptom. If you scheduled it as routine screening, push back and confirm modifier 33 or PT was applied.
- Anesthesiologist billed out-of-network when the facility and gastroenterologist are in-network. Under the No Surprises Act, your liability is capped at your in-network cost-sharing; dispute any balance bill above that amount.
- Both the diagnostic endoscopy code and the biopsy or polypectomy code billed for the same session. When tissue is removed, only the biopsy or polypectomy code, which already includes the base endoscopy, should be billed.
- Hospital outpatient facility rate billed for a procedure actually performed at an affiliated ASC or off-campus GI center. Compare the site address on your bill against where the procedure actually took place.
- Capsule endoscopy device cost billed separately as durable medical equipment when it should be bundled into the global procedure fee. Ask for an itemized bill and confirm the device charge is not duplicated.
Frequently Asked Questions
How much does an endoscopy cost without insurance in 2026?
Endoscopy pricing depends entirely on which type you need. Without insurance in 2026, flexible sigmoidoscopy costs $500 to $1,500, upper endoscopy (EGD) costs $1,200 to $5,500, colonoscopy costs $1,250 to $4,800, and capsule endoscopy costs $900 to $3,500. A combined upper and lower endoscopy on the same day can run $2,500 to $7,500. Site of service matters as much as procedure type: an ambulatory surgery center typically charges half to a third of what a hospital outpatient department charges for the identical scope.
What does Medicare pay for an endoscopy in 2026?
Original Medicare pays the gastroenterologist under the 2026 Physician Fee Schedule: approximately $111 for a facility-based upper endoscopy, approximately $400 for a colonoscopy, and $53 to $215 for a flexible sigmoidoscopy. The facility receives a separate payment of $420 to $680 at an ASC or $650 to $1,260 at a hospital outpatient department. Screening colonoscopy and screening flexible sigmoidoscopy are covered at 100% with no deductible or coinsurance. Diagnostic endoscopy of any type carries the standard 20% coinsurance after the 2026 Part B deductible of $283.
How do I request a Good Faith Estimate for an endoscopy?
Call the facility, say you are self-pay or uninsured, and ask for a written Good Faith Estimate itemizing the physician fee, facility fee, anesthesia fee, and any expected pathology charges. Under the No Surprises Act, the estimate must arrive at least 3 business days before your procedure if scheduled 10 or more business days out, or at least 1 business day before service if scheduled 3 to 9 business days out. Keep the estimate; you can dispute a final bill that exceeds it by $400 or more.
What is the No Surprises Act and does it apply to me?
The No Surprises Act, effective January 2022, protects self-pay and uninsured patients with the right to a written Good Faith Estimate before scheduled care, and protects insured patients from most surprise out-of-network bills from providers like anesthesiologists at in-network facilities. It applies to nearly every hospital, ASC, and physician office, though not to Medicare or Medicaid, which have their own protections. If your endoscopy bill exceeds the Good Faith Estimate by $400 or more, or you get an unexpected out-of-network bill, you can dispute it through CMS.
How do I get a written cash-pay quote for an endoscopy?
Call the scheduling office directly and ask specifically for the self-pay or cash-pay price, not just the standard chargemaster rate. Many ASCs and independent GI practices publish bundled cash rates of $1,200 to $2,500 that include the facility, physician, and anesthesia. Ask the quote to be put in writing as a Good Faith Estimate under the No Surprises Act, and confirm whether pathology and anesthesia are included or billed separately.
Can I negotiate an endoscopy bill after the fact?
Yes. Even after receiving a bill, call the billing office and ask for the self-pay or prompt-pay discount rate, which is often 20 to 60 percent off the chargemaster price. Offer to pay a lump sum immediately in exchange for a further reduction. If the final bill exceeds a Good Faith Estimate you received before the procedure by $400 or more, you have 120 days from the bill date to file a formal patient-provider dispute resolution claim at cms.gov/nosurprisesact instead of negotiating informally.
What's the difference between hospital and ASC/office endoscopy cost?
The procedure itself is identical: same gastroenterologist, same equipment, same sedation. Only the facility billing code differs. An ambulatory surgery center or office-based suite bills a lower facility fee because it carries lower overhead than a hospital, which allocates emergency-room and surgical-suite costs across every bill. Under 2026 Medicare rates, an ASC facility fee runs $420 to $680 versus $650 to $1,260 at a hospital outpatient department for the same procedure. Cash-pay prices follow a similar 2x to 3x ratio.
Is endoscopy covered by ACA preventive care?
Partially. Screening colonoscopy and screening flexible sigmoidoscopy carry a USPSTF Grade A recommendation for average-risk adults age 45 and older, so ACA-compliant plans must cover them at 100% with no cost-sharing. Upper endoscopy (EGD) and capsule endoscopy have no USPSTF preventive recommendation for asymptomatic adults, so they are covered like any other diagnostic service, subject to your plan's deductible and coinsurance.
What's the difference between an upper endoscopy and a colonoscopy?
An upper endoscopy (EGD) examines the esophagus, stomach, and duodenum through the mouth, typically ordered for heartburn, difficulty swallowing, or suspected ulcers. A colonoscopy examines the entire colon through the rectum, typically ordered as colorectal cancer screening or to investigate bleeding, anemia, or a change in bowel habits. Both are usually performed by a gastroenterologist under sedation and can be scheduled the same day, but colonoscopy has dedicated screening HCPCS codes (G0105, G0121) that make it eligible for 100% coverage; upper endoscopy does not.
What is capsule endoscopy and how much does it cost?
Capsule endoscopy uses a pill-sized camera that the patient swallows, which photographs the small intestine, an area that a standard upper endoscopy or colonoscopy cannot reach, as it travels through the digestive tract over about 8 hours. Without insurance in 2026, capsule endoscopy typically costs $900 to $3,500, including the device, the physician's interpretation, and a follow-up visit to review images. It is not a preventive service and often requires prior authorization on Medicare Advantage and commercial plans because of its cost relative to other diagnostic options.
