Colonoscopy Cost Without Insurance: Free Options for Black Adults

A colonoscopy generates four separate bills (doctor, facility, anesthesia, and pathology if a polyp comes out), which is why nobody can quote you one national price. What the federal government does publish is revealing: in 2024 Medicare claims data, physicians billed an average of $1,419 for the colonoscopy procedure fee alone (code 45378), and Medicare approved $242 of it. That gap is the whole game for anyone paying cash. Below: the verifiable numbers and six routes to cheaper screening.

The U.S. Preventive Services Task Force recommends colorectal cancer screening for all adults 45 to 75. Its 2021 recommendation grades ages 45 to 49 a B and 50 to 75 an A, and those grades trigger free preventive coverage under federal law. The American Cancer Society agrees: people at average risk start regular screening at 45.

For Black adults, 45 is not a birthday to let slide. Colorectal cancer is the third most common cancer and the third leading cause of cancer death in Black men and women, per the American Cancer Society's 2025 report. Federal SEER data for 2019 to 2023 puts new diagnoses at 50.1 per 100,000 Black men and 37.1 per 100,000 Black women per year, with death rates of 20.5 and 13.2. Screening exists because polyps can be found and removed before they ever become cancer. Yet only about 64% of Black adults 45 and older are up to date, which leaves more than one in three overdue. Cost is the reason this guide can fix. Our guide to colon cancer screening for Black adults compares every test.

No agency publishes an official national price for a colonoscopy without insurance, and any site quoting a single average is guessing. Three benchmarks you can verify yourself:

• The Medicare rate. In CMS's 2024 claims data, the average Medicare-approved amount for the physician fee for a diagnostic colonoscopy (code 45378) in a hospital or surgery-center setting was $242, while the average charge physicians submitted was $1,419. That is the doctor's fee alone: the facility, the anesthesia clinician, and the pathology lab each bill separately.
• Hospital cash prices. Every U.S. hospital must post its standard charges online, including the discounted cash price it accepts from self-pay patients, and CMS names colonoscopy as a shoppable service hospitals must display. Search the hospital's name plus "price transparency".
• The setting discount. Medicare's 2025 base payment rate for ambulatory surgical centers is 62% of the rate for hospital outpatient departments. A freestanding endoscopy or surgery center is structurally the cheaper building. Start your cash-price calls there, then compare settings with Medicare's Procedure Price Lookup tool.

The $1,419 submitted charge above is a list price, and uninsured patients are the only people routinely billed list. Ask for the cash price and an itemized estimate in writing before the procedure; the disclosure rules exist so you can.

1. Private insurance, including every Marketplace plan: $0 in network. Federal law requires most private plans to cover colorectal cancer screening for adults 45 to 75 with no copay, coinsurance, or deductible at an in-network provider; HealthCare.gov lists the benefit by name. Federal guidance extends the $0 to everything integral to a screening colonoscopy: the pre-procedure consult, bowel prep drugs, anesthesia, polyp removal, and pathology on any polyp removed.

2. The follow-up colonoscopy after a positive stool test: also $0. Few people know this loophole got closed. For plan years beginning on or after May 31, 2022, federal guidance (FAQs About Affordable Care Act Implementation Part 51, Q7) requires plans to cover a colonoscopy after a positive stool-based test or CT colonography with no cost sharing, because the follow-up is "an integral part of the preventive screening without which the screening would not be complete." If a bill arrives anyway, appeal and cite that FAQ by name.

3. Medicare: $0 screening, on a schedule. Part B covers a screening colonoscopy at no cost when your provider accepts assignment: every 120 months at average risk, every 24 months at high risk, with no minimum age. A follow-up colonoscopy after a positive stool or blood-based screening test is also covered as a screening. The caveat: if a polyp is found and removed, Medicare charges 15% coinsurance for the provider's services, plus 15% to the facility. The Part B deductible does not apply.

4. Medicaid covers screening. Which tests and how often can vary by state, so call the member services number on your card and ask what is covered and where. Since 2022, CMS has graded state Medicaid programs on the share of enrolled adults up to date with colorectal cancer screening.

5. No insurance: start at a community health center. Federally funded health centers adjust fees to your income and family size and serve everyone, including patients who cannot pay. They are the cheapest legitimate front door: a low-cost visit, a stool test, and a referral if the result requires a colonoscopy. Find one near you through findahealthcenter.hrsa.gov or our clinic directory, and see our guide to community health centers for how the sliding scale works.

6. CDC-funded screening programs. The CDC's Colorectal Cancer Control Program funds 38 grantees, including 21 states and several tribal organizations, working through clinics that serve people behind on screening. Ask your health center or state health department whether it participates and what no-cost screening it offers.

Across all six routes, stool-based tests are the legitimate cheap first step. The USPSTF lists an annual FIT (fecal immunochemical test) and a stool DNA test every 1 to 3 years as recommended strategies alongside the 10-year colonoscopy, and Medicare covers the stool DNA test (sold as Cologuard) every 3 years at $0 for average-risk adults 45 to 85. A positive stool test means you still need the colonoscopy; the coverage fix in route 2 exists so that next step does not cost you either.

The word "screening" is doing legal work on your bill. A colonoscopy ordered because you have symptoms is diagnostic from the start, and the $0 preventive rules never attach to it. A screening colonoscopy that finds a polyp must still be billed as preventive under private insurance, with polyp removal and pathology riding along at $0. Even so, before you book, ask the scheduler, the gastroenterology office, and the facility the same question: "Will this be billed as a preventive screening, and will it stay preventive if you remove a polyp?" Then confirm the anesthesia clinician and pathology lab are in network. Five minutes of phone calls beats months of appeals.

Insured: call your plan, confirm the preventive screening benefit for adults 45 and up, book with an in-network gastroenterologist, and ask the billing question above. Uninsured: call a community health center for a FIT test and a sliding-scale visit, and ask about CDC-funded screening in your area. Either way, find a Black gastroenterologist or primary care clinician in our directory. Bring one question to the visit: "Which screening test can I actually complete this year, given my coverage?" The best test is the one that gets done.
