How Much Does a Colonoscopy Cost? (2026 Guide to Prices, Insurance, and Out-of-Pocket Costs)

What a colonoscopy costs depends mostly on two things: whether it's a screening or a diagnostic procedure, and whether you have health insurance. Under the Affordable Care Act, a routine screening colonoscopy is usually fully covered with an in-network provider. Without insurance, the hospital facility fee alone has a median self-pay price of about $1,746, with most hospitals charging between about $630 and $3,940, according to Self Pay Rates, which compiles prices from 1,439 U.S. hospitals. The physician, anesthesia, and any pathology services are usually billed separately.

Colonoscopy Cost at a Glance

• Screening colonoscopy with insurance: usually $0 in-network, including when a polyp is removed during the screening
• Diagnostic colonoscopy with insurance: your deductible, copay, and coinsurance apply
• Uninsured patients: a median of about $1,746 for the hospital facility fee alone, plus separate bills for the gastroenterologist, anesthesia, and pathology
• Medicare: a screening colonoscopy is covered; if a polyp is removed, you pay 15% of the Medicare-approved amount for the doctor's services and a 15% coinsurance for the facility

Cost should not delay a screening that could prevent colon cancer. Finding and removing precancerous polyps during a colonoscopy is one of the most effective ways to prevent the disease. The rest of this guide breaks down each part of colonoscopy pricing so you can plan, budget, and avoid surprise bills.

What Is a Colonoscopy?

A colonoscopy is a medical procedure in which a doctor guides a flexible tube with a camera (a colonoscope) through the rectum and the entire colon. The camera lets the physician look for colon polyps, bleeding, inflammation, and other problems. If the doctor finds a polyp or suspicious tissue, instruments passed through the scope can remove it or take a biopsy during the same procedure.

The U.S. Preventive Services Task Force recommends colorectal cancer screening for adults at average risk starting at age 45. A colonoscopy is one of several screening options and, if the results are normal, is typically repeated every 10 years. People with a family history of colorectal cancer or a personal history of polyps may need to start earlier and have more frequent screenings, based on their healthcare provider's advice.

A diagnostic colonoscopy is ordered to investigate symptoms, for example if you notice blood in your stool, have unexplained weight loss, or have iron-deficiency anemia, or to follow up on known disease.

Screening vs. Diagnostic Colonoscopy: Why It Changes What You Pay

Whether a colonoscopy is billed as screening or diagnostic determines your cost-sharing.

• Screening colonoscopy. For adults ages 45 to 75, colorectal cancer screening is one of the preventive services that plans following the Affordable Care Act must cover without a copay or coinsurance when you use an in-network provider.
• Diagnostic colonoscopy. When the procedure is done because of symptoms or to monitor a known condition, standard cost-sharing applies: your deductible, copays, and coinsurance.
• Polyp removal during a screening. Federal guidance says that when an in-network provider removes a polyp during a preventive colonoscopy, the insurance plan should still cover it as preventive care without cost-sharing (U.S. Department of Labor, ACA FAQs Part 68).
• Follow-up after a positive stool test. Plans must also cover a follow-up colonoscopy after a positive stool-based screening test without cost-sharing (ACA FAQs Part 51).

Billing still matters. If a screening is coded as diagnostic by mistake, your insurance company may apply cost-sharing. Confirm with your plan before the appointment how it handles polyp removal, and check your explanation of benefits afterward.

How Much Does a Colonoscopy Cost Without Insurance?

Uninsured patients usually receive several separate bills:

• Facility fee for the hospital outpatient department or ambulatory surgery center
• Physician fee for the gastroenterologist who performs the procedure
• Anesthesia fee, if an anesthesiologist or nurse anesthetist provides sedation
• Pathology services, if tissue is removed and sent to a lab

At hospitals, the facility fee for a diagnostic colonoscopy (CPT code 45378) has a median self-pay price of about $1,746, with most hospitals charging between about $630 and $3,940, according to Self Pay Rates. State medians range widely, from about $471 in Puerto Rico to about $3,968 in Georgia. If the doctor takes a biopsy or removes a polyp, the procedure is billed under a different code and costs more, plus pathology charges.

Independent ambulatory surgery centers often cost less than hospital outpatient departments, and some publish bundled self-pay prices that include the facility, doctor, and sedation. Ask every provider for a written, all-inclusive quote that says whether anesthesia and pathology are included, and ask about cash discounts for paying in advance.

If you're uninsured or paying yourself, the No Surprises Act gives you the right to a good faith estimate before scheduled care. Community health centers and nonprofit hospitals with financial assistance programs may offer lower-cost options, and some hospitals and health departments occasionally hold free colonoscopies or low-cost screening events for eligible uninsured patients.

Colonoscopy Prices by Setting and Location

Where you have the procedure is one of the biggest price drivers. Hospital outpatient departments usually charge higher facility fees than independent ambulatory surgery centers, and prices vary by state and even within the same city, because network contracts and local competition differ.

Compare quotes from at least two or three providers, and ask whether each quote includes the doctor, facility, anesthesia, and pathology. Your insurer's cost estimator and hospital price transparency tools can be good starting points.

How Health Insurance Affects the Cost of a Colonoscopy

What you pay with insurance depends on your plan type, how much of your deductible remains, and whether every provider involved is in-network.

For a screening colonoscopy that's billed correctly and done in-network, insurance coverage under the Affordable Care Act generally means no cost-sharing for adults 45 to 75.

For a diagnostic colonoscopy, normal cost-sharing applies. Until you meet your deductible, you may owe the full negotiated price. After that, you pay coinsurance until you reach your out-of-pocket maximum.

Medicare covers screening colonoscopies once every 120 months for people at average risk (or 48 months after a previous flexible sigmoidoscopy) and once every 24 months for people at high risk. You pay nothing for the screening if your provider accepts assignment. If a polyp is removed, you pay 15% of the Medicare-approved amount for the doctor's services and a 15% coinsurance in a hospital outpatient setting or surgery center, according to Medicare.gov.

Call your insurance company with the procedure and diagnosis codes from your doctor's office to get a personalized estimate.

What's Included in the Cost of a Colonoscopy (and Additional Costs)

A single colonoscopy can produce several bills from different providers:

• Gastroenterologist's fee for performing the procedure
• Facility fee for the endoscopy suite or operating room
• Anesthesia, if you have deep sedation from an anesthesiologist or nurse anesthetist rather than moderate sedation given by the GI team
• Pathology for any polyps or biopsies
• Pre-procedure visits, in person or by telehealth
• Bowel prep medication, which depends on your prescription coverage

Some surgery centers offer bundled prices that combine the facility, doctor, and sedation. Others bill each item separately, which makes the final total harder to predict.

A commonly missed additional cost is a separate bill from an out-of-network anesthesiologist or pathology lab at an in-network facility. Ask in advance which providers will be involved and whether they're in your network.

Understanding Out-of-Pocket Costs: Deductibles, Copays, and Coinsurance

Four terms control what patients pay for a diagnostic colonoscopy: the deductible, copay, coinsurance, and out-of-pocket maximum.

For example, imagine two people on the same plan with a $2,000 deductible. One has a diagnostic colonoscopy in January before any other medical bills, so they pay the full negotiated price, say $1,800. The other has the same procedure in November after already meeting the deductible, so they pay only their coinsurance share, for example 20%, or $360.

Out-of-network care can mean higher coinsurance, a separate out-of-network deductible, and bills from providers without contracted rates. Review your plan's summary of benefits and coverage for its preventive colonoscopy rules.

Ways to Manage the Cost

• Ask for self-pay prices. Many hospitals and GI practices offer cash discounts. Get them in writing before the procedure.
• Compare settings. Independent endoscopy centers are often less expensive than hospital outpatient departments.
• Apply for financial assistance. Nonprofit hospitals are required to have financial assistance policies. If your income qualifies, the hospital may reduce or cover your bill.
• Ask about payment plans. Many providers will spread a balance over several months.
• Plan around your deductible. If you've already met your deductible this year, a diagnostic colonoscopy may cost less now than in January.

Whether you can pay with an HSA or FSA depends on your plan, and IRS Publication 502 describes which medical expenses qualify. Our guide to HSAs and FSAs explains how the two accounts work.

What Happens During a Colonoscopy, and How It Affects Cost

1. Check-in: You change into a gown and have an IV placed, and a nurse reviews your medical history and insurance information.
2. Sedation: The GI team gives moderate sedation, or an anesthesiologist or nurse anesthetist gives deep sedation. Deep sedation adds a separate professional fee.
3. The exam: The doctor examines the entire colon, which usually takes 30 to 60 minutes.
4. Polyp removal or biopsy: Removing polyps or taking biopsies can add procedure time and pathology fees, and changes the billing code.
5. Recovery area: You rest until the sedation wears off and need someone to drive you home.

Completing the bowel prep fully lowers the chance of an incomplete exam that would need to be repeated and paid for again. If your doctor mentions a virtual colonoscopy (CT colonography), keep in mind that an abnormal result usually leads to a standard colonoscopy, which has its own cost.

Billing Pitfalls and How to Avoid Them

Common billing problems include:

• A screening colonoscopy coded as diagnostic by mistake
• Polyp removal being treated as diagnostic when it should be covered as preventive
• An out-of-network anesthesiologist or pathology lab at an in-network facility
• Separate charges for pre-procedure visits or bowel prep that you weren't expecting

Before the procedure:

1. Ask your healthcare provider's office for the procedure and diagnosis codes.
2. Call your insurer to confirm coverage, including what happens if a polyp is removed.
3. Confirm that the facility, GI doctor, anesthesia group, and pathology lab are all in-network.

After the procedure, compare your explanation of benefits with your bills. If a screening was billed as diagnostic, call your insurer and the provider's billing office, and keep notes of every call. You have the right to request an itemized bill.

Planning Your First Colonoscopy

Most adults at average risk should start colorectal cancer screening at 45. People with a strong family history, certain genetic conditions, or inflammatory bowel disease may need to start earlier and screen more often.

To budget for your first colonoscopy:

• Get cost estimates from every provider involved: the facility, the doctor, the anesthesia group, and the pathology lab.
• Check whether your plan covers the bowel prep medication.
• Arrange a ride home and time off work.

Knowing the cost ahead of time makes it easier to schedule a screening on time, and getting screened is far less expensive than treating colon cancer found at a later stage.
