Colorectal cancer is the third most common cancer in the United States, yet roughly one in three eligible adults still skip their recommended screening. Understanding the colonoscopy cost before you schedule the procedure can remove one of the biggest barriers to getting screened. Prices swing wildly depending on your insurance status, the facility you choose, and where you live. This guide breaks down exactly what you can expect to pay in 2026.
Average Colonoscopy Cost in 2026
The cost of a colonoscopy in the United States typically ranges from $1,250 to $4,800 without insurance, according to data from the Centers for Medicare and Medicaid Services (CMS). That figure covers the facility fee, the physician fee, anesthesia, and pathology if biopsies are taken. However, the national average hovers around $2,750 for an outpatient diagnostic colonoscopy performed at an ambulatory surgery center.
Several variables push that number higher or lower. A screening colonoscopy — one performed on a patient with no symptoms and no prior findings — is generally less expensive than a diagnostic colonoscopy ordered because of symptoms like rectal bleeding or a family history of polyps. Geographic location matters too: patients in metropolitan areas on the East and West Coasts often pay 30 to 50 percent more than those in the Midwest or South.
Colonoscopy Cost With Insurance
Under the Affordable Care Act, most private insurance plans must cover a screening colonoscopy at no out-of-pocket cost for adults aged 45 and older. That means zero copay, zero deductible, and zero coinsurance — as long as the procedure is classified as preventive. Medicare Part B also covers screening colonoscopies every 10 years for average-risk beneficiaries, or every two years for those at high risk, with no cost-sharing requirement.
The catch is what happens during the procedure. If a polyp is found and removed, some insurers have historically reclassified the visit from “screening” to “diagnostic,” triggering cost-sharing. Federal rules have been tightening this loophole, but you should still confirm your plan’s policy before the procedure. When a colonoscopy is coded as diagnostic, insured patients typically pay between $200 and $1,500 out of pocket, depending on their deductible and coinsurance rate.
Always call your insurer ahead of time and get pre-authorization in writing. Ask specifically whether polyp removal during a screening colonoscopy will change your cost-sharing responsibility.
Colonoscopy Cost Without Insurance
Uninsured patients face the steepest prices because they are billed at the facility’s chargemaster rate — the list price before any negotiated discounts. Without insurance, the colonoscopy cost can range from $1,250 at a standalone ambulatory surgery center to $4,800 or more at a hospital outpatient department. The breakdown generally looks like this:
- Facility fee: $800 – $3,200
- Physician (gastroenterologist) fee: $250 – $800
- Anesthesia fee: $200 – $600
- Pathology (if biopsies taken): $100 – $400
You may also incur costs for the pre-procedure consultation and the bowel prep kit, which runs $20 to $75 at most pharmacies. Some facilities bundle these into a single cash-pay price, while others bill each component separately — so always ask for an itemized estimate.
Factors That Affect Colonoscopy Pricing
Facility type is the single biggest cost driver. Hospital outpatient departments charge, on average, 60 to 80 percent more than freestanding ambulatory surgery centers for the same procedure, according to a CMS payment comparison. The clinical outcome is essentially the same in both settings for routine colonoscopies, so choosing an ambulatory center is one of the easiest ways to lower your bill.
Anesthesia type also plays a role. Moderate (conscious) sedation administered by the gastroenterologist costs less than monitored anesthesia care (MAC) provided by a separate anesthesiologist. MAC has become the standard at many facilities because patients prefer being fully asleep, but it adds $200 to $600 to the total bill.
Finally, your geographic region matters. Prices in New York City, San Francisco, and Boston consistently rank among the highest in the country. Rural areas in the South and Midwest often have the lowest costs. If you live near a state border, it may be worth comparing prices in both states.
How to Save Money on a Colonoscopy
Price transparency is your most powerful tool. Under federal rules that took effect in 2021 and have been strengthened since, hospitals must publish machine-readable files of their negotiated rates. Use those files — or consumer-friendly tools built on them — to compare colonoscopy prices at facilities in your area. You can also check the Medicare Procedure Price Lookup Tool for a baseline reference.
If you are uninsured, ask about the facility’s self-pay or cash-pay discount. Many ambulatory surgery centers offer bundled pricing between $1,250 and $2,000 for cash patients, which can be significantly lower than the unbundled chargemaster rate. Transparent pricing platforms like Sesame and MDsave list colonoscopy packages you can purchase upfront.
Other strategies that work:
- Negotiate before the procedure. Call the billing department and ask for their best cash price. Offer to pay in full on the day of service in exchange for a discount.
- Use an HSA or FSA. If you have a health savings account or flexible spending account, the entire colonoscopy cost is an eligible expense.
- Look into free screening programs. Organizations like the American Cancer Society maintain lists of low-cost and free colorectal cancer screening programs by state.
- Ask about payment plans. Most facilities offer interest-free payment plans that spread the cost over 6 to 12 months.

Screening Colonoscopy vs. Diagnostic Colonoscopy: Cost Differences
The distinction between screening and diagnostic is not just clinical — it directly affects your wallet. A screening colonoscopy is performed on an asymptomatic patient as part of routine colorectal cancer prevention. Under ACA rules, it must be covered without cost-sharing by most health plans. A diagnostic colonoscopy, on the other hand, is ordered because you are experiencing symptoms (bleeding, unexplained weight loss, chronic diarrhea) or have abnormal findings from another test.
Diagnostic colonoscopies are subject to your plan’s normal cost-sharing rules — deductible, copay, and coinsurance all apply. This means the same physical procedure, performed by the same doctor in the same room, can cost you $0 or $1,500 depending on how it is coded. If your doctor orders a colonoscopy, ask whether it will be classified as screening or diagnostic and what that means for your expected out-of-pocket amount.
What Medicare and Medicaid Cover
Medicare Part B covers screening colonoscopies every 10 years for beneficiaries at average risk and every two years for those at high risk. There is no deductible or coinsurance for the screening itself, though you may owe 20 percent of the Medicare-approved amount if a polyp is removed — a gap that Congress has been working to close. According to Medicare.gov, the Medicare-approved amount for a screening colonoscopy ranges from roughly $500 to $1,200 depending on facility type and region.
Medicaid coverage varies by state. Most state Medicaid programs cover screening colonoscopies for beneficiaries over 45, but some require prior authorization or limit the approved facilities. Check your state Medicaid website or call your managed care plan for specifics.
If you are comparing CT scan costs as an alternative screening method, keep in mind that CT colonography (virtual colonoscopy) is not yet universally covered by Medicare or private insurance for routine screening purposes.
Frequently Asked Questions
How much does a colonoscopy cost at an ambulatory surgery center vs. a hospital?
An ambulatory surgery center typically charges $1,250 to $2,500 for a colonoscopy, while a hospital outpatient department may charge $2,500 to $4,800 for the same procedure. The clinical quality is comparable for routine colonoscopies, making surgery centers the more cost-effective option for most patients.
Will I owe anything if a polyp is found during a screening colonoscopy?
Federal rules increasingly protect patients from surprise cost-sharing when polyps are removed during a screening colonoscopy. However, some plans may still reclassify the procedure as diagnostic. Contact your insurer before your appointment to confirm their policy in writing.
Is a colonoscopy cheaper with a payment plan?
A payment plan does not reduce the total colonoscopy cost, but it makes the expense more manageable by spreading it over several months. Many facilities offer zero-interest payment plans. Some also offer a discount of 10 to 20 percent if you pay the full amount upfront in cash.
How often should I get a colonoscopy?
The American Cancer Society recommends that adults at average risk begin screening at age 45 and repeat every 10 years if results are normal. Those with a family history of colorectal cancer or polyps may need screening more frequently — sometimes every 3 to 5 years. Your gastroenterologist will recommend a schedule based on your individual risk factors.
Are there cheaper alternatives to a colonoscopy?
Stool-based tests like FIT (fecal immunochemical test) and Cologuard cost between $25 and $650 and can be done at home. They are less invasive but also less accurate for detecting polyps. If a stool test comes back positive, you will still need a follow-up colonoscopy. For many patients, starting with a stool test is a reasonable first step, particularly when cost is a concern.
The Bottom Line
The colonoscopy cost ranges from $0 for an insured screening to nearly $5,000 for an uninsured diagnostic procedure at a hospital. Your best strategies for lowering the price include choosing an ambulatory surgery center, confirming your insurance classification before the appointment, and negotiating a cash-pay rate if you are uninsured. Colorectal cancer is highly preventable when caught early — do not let cost uncertainty keep you from scheduling this important screening.
