How Much Does a Colonoscopy Cost? (With & Without Insurance)

What does a colonoscopy cost without insurance?

Self-pay prices for a colonoscopy vary considerably across care settings:

• Ambulatory surgery center (ASC) or endoscopy center: generally $1,500–$3,000 all-in, including sedation. ASCs are accredited outpatient facilities that perform colonoscopies routinely and are clinically equivalent to hospitals for routine screening 3Ref 3National Institute of Diabetes and Digestive and Kidney Diseases (2024).Colonoscopy.Colonoscopy procedure overview, preparation, and age 45 screening recommendation from official NIDDK patient resource.
• Hospital outpatient department: typically $2,500–$4,500 or more. Hospitals add a facility fee that drives the total price up significantly.
• Gastroenterologist fee: usually $300–$700, billed separately from the facility.
• Anesthesia: $300–$600, billed by the anesthesiologist or CRNA.
• Pathology: if polyps are removed, tissue analysis adds $200–$600 per specimen.

Asking the facility for an all-inclusive self-pay estimate — covering physician, facility, anesthesia, and pathology — before booking prevents billing surprises. Many facilities offer a cash-pay discount for uninsured patients who ask.

Does insurance cover a colonoscopy?

Preventive screening colonoscopy: Under the Affordable Care Act (ACA), non-grandfathered health plans must cover USPSTF A- and B-grade preventive services at zero cost-sharing. The USPSTF assigns a Grade B recommendation to colorectal cancer screening starting at age 45 for average-risk adults 2Ref 2US Preventive Services Task Force (2021).Screening for Colorectal Cancer: US Preventive Services Task Force Recommendation Statement.Grade B recommendation for colorectal cancer screening starting at age 45; ACA requires coverage of USPSTF A/B preventive services at zero cost-sharing. This means a screening colonoscopy ordered as a preventive service must be covered at 100% with no deductible or copay on qualifying plans.

Important caveat — the polyp reclassification problem: Some insurance plans reclassify a screening colonoscopy as diagnostic or therapeutic when polyps are found and removed, triggering cost-sharing. Under CMS rules, plans may not impose cost-sharing for polyp removal during a preventive screening colonoscopy, but many consumers are still billed. Always confirm your plan's specific policy on polyp removal before the procedure.

Diagnostic colonoscopy (ordered for symptoms such as bleeding, pain, or a change in bowel habits): this is not classified as preventive and is subject to your normal deductible and cost-sharing.

Medicare: Medicare Part B covers screening colonoscopies for most beneficiaries at 100% (no deductible) on the established frequency — every 10 years for average-risk and every 2 years for high-risk individuals. If a polyp is removed, a 15% coinsurance of the Medicare-approved amount may apply.

Key questions to ask your insurer before scheduling: - Is this colonoscopy being billed as preventive or diagnostic? - Does polyp removal during a preventive colonoscopy change my cost-sharing? - Are the gastroenterologist, the facility, and the anesthesiologist all in-network?

At what age should I get a colonoscopy?

The ACG's 2021 colorectal cancer screening guideline and the 2021 USPSTF recommendation both support colorectal cancer screening starting at age 45 for average-risk adults 1Ref 1Shaukat A, Kahi CJ, Burke CA, Rabeneck L, Sauer BG, Rex DK (2021).ACG Clinical Guidelines: Colorectal Cancer Screening 2021.Colonoscopy as a first-tier screening option; FIT as an alternative; screening recommended starting at age 45 for average-risk adults2Ref 2US Preventive Services Task Force (2021).Screening for Colorectal Cancer: US Preventive Services Task Force Recommendation Statement.Grade B recommendation for colorectal cancer screening starting at age 45; ACA requires coverage of USPSTF A/B preventive services at zero cost-sharing. Earlier or more frequent screening is recommended for people with:

• A personal or family history of colorectal cancer or advanced polyps
• Inflammatory bowel disease (Crohn's disease or ulcerative colitis)
• Certain hereditary syndromes (Lynch syndrome, familial adenomatous polyposis)

Your primary care provider or gastroenterologist can assess your personal risk and advise on the right starting age and interval.

How can I reduce what I pay?

• Choose an ASC over a hospital: for a scheduled elective colonoscopy, an accredited ambulatory surgery center is clinically equivalent and often $1,000–$2,000 less expensive than a hospital outpatient department 3Ref 3National Institute of Diabetes and Digestive and Kidney Diseases (2024).Colonoscopy.Colonoscopy procedure overview, preparation, and age 45 screening recommendation from official NIDDK patient resource.
• Confirm everything is in-network: the gastroenterologist, facility, and anesthesiologist can each be billed separately — any one being out-of-network can create a large unexpected charge.
• Ask about the cash-pay rate: if you are uninsured, always ask for the self-pay discount; most facilities have one.
• Use your HSA or FSA: colonoscopies are a qualified medical expense payable with pre-tax dollars.
• Check state screening programs: for low-income uninsured adults, many states run colorectal cancer screening programs that cover the procedure at no cost. Ask your primary care provider or local health department.
• Consider non-colonoscopy screening alternatives: stool-based tests (FIT annually or stool DNA test every 1–3 years) are lower-cost options for average-risk screening. A positive stool-based result still requires a follow-up colonoscopy 1Ref 1Shaukat A, Kahi CJ, Burke CA, Rabeneck L, Sauer BG, Rex DK (2021).ACG Clinical Guidelines: Colorectal Cancer Screening 2021.Colonoscopy as a first-tier screening option; FIT as an alternative; screening recommended starting at age 45 for average-risk adults2Ref 2US Preventive Services Task Force (2021).Screening for Colorectal Cancer: US Preventive Services Task Force Recommendation Statement.Grade B recommendation for colorectal cancer screening starting at age 45; ACA requires coverage of USPSTF A/B preventive services at zero cost-sharing.

Who performs a colonoscopy?

A gastroenterologist performs colonoscopies. If you do not have one, your primary care provider can give a referral. Gale can help you identify a GI specialist and understand what to expect when you call to schedule.
