If you have insurance or Medicare, a routine screening colonoscopy often costs you nothing at the time of service. If you pay cash, published Houston prices for a colonoscopy start around $1,150 for an all-in bundle and climb well past that when each provider bills separately.
That gap is why colon cancer screening cost in Houston is hard to pin down. The same procedure can produce four separate bills, and the test you choose, your plan type and whether a polyp gets removed all change what you owe.
This guide breaks down each fee, compares stool tests with colonoscopy, and shows you what to ask before you book so you get a written number instead of a surprise.
Colon cancer screening costs at a glance
Most adults at average risk should start screening at 45, according to the U.S. Preventive Services Task Force. Here is how the main cost scenarios compare.
| Your situation | What you will likely pay |
|---|---|
| Private insurance, in-network, routine screening | Often $0 for the screening itself; ask about polyp removal, pathology and anesthesia |
| Traditional Medicare, provider accepts assignment | $0 for the screening; 15% coinsurance in 2026 if a polyp is removed |
| Self-pay, bundled colonoscopy price | About $1,150 for one advertised Houston bundle that includes physician, facility, anesthesia and pathology |
| Self-pay, billed separately | Varies widely; one Houston price index shows a $1,594 median |
| Self-pay, at-home stool DNA test | $790 manufacturer self-pay price for Cologuard Plus |
Treat these as starting points. Only your plan and your provider can give you a final figure.
Screening test cost comparison
Colorectal cancer screening comes in two broad forms: at-home stool tests and visual exams like colonoscopy. A stool test costs less up front. A colonoscopy costs more but lasts longer and lets the doctor remove polyps on the spot.
| Test | How often (average risk) | Published self-pay price | Follow-up needed if positive |
|---|---|---|---|
| FIT (fecal immunochemical test) | Every year | Ask the lab or office; usually the lowest-cost option | Yes, a colonoscopy |
| Stool DNA-FIT (Cologuard Plus) | Every 1 to 3 years | $790 self-pay (manufacturer) | Yes, a colonoscopy |
| Colonoscopy | Every 10 years | About $1,150 bundled in Houston; more when billed separately | Polyps are usually removed during the same exam |
Why the cheaper test is not always cheaper
A positive stool test means you still need a colonoscopy. If you pay cash, you would pay for both. A stool test also repeats every one to three years, while a normal colonoscopy usually holds for ten.
Insured patients have better protection here than they did a few years ago. Federal rules now treat the follow-up colonoscopy after a positive stool test as part of the screening (more on that below).
Which test is right for you
The best test is the one you will complete. Dr. Maher can help you weigh your risk, your health history and your budget. You can read more about the options on our colon cancer screening page.
Physician, facility, anesthesia and pathology fees
A colonoscopy bill is rarely one line. Up to four parties can charge for the same visit. Knowing each one helps you ask the right questions.
Physician fee
This pays the gastroenterologist who performs the exam. At our practice, Dr. James Maher personally performs every colonoscopy. The physician fee rises if he takes a biopsy or removes a polyp, because those are billed as separate procedure codes.
Facility fee
This covers the room, equipment, nurses and recovery area. It is usually the largest part of the bill. Hospital outpatient departments tend to charge more than ambulatory surgery centers or office-based settings for the same procedure.
Anesthesia or sedation fee
If an anesthesiologist or nurse anesthetist manages your sedation, expect a separate bill from that provider. Ask who provides sedation and whether that provider is in your network.
Pathology fee
Any tissue or polyp removed goes to a lab, and the pathologist bills separately. A screening with no polyps may have no pathology charge. A screening with three polyps may have three specimens to read.
Costs people forget
- Bowel prep medicine, which federal rules do not require plans to cover at no cost
- A pre-procedure office visit, if your health history requires one
- Follow-up visits or imaging if results need more work
Eligible patients can skip the pre-procedure visit through our Direct Access Colonoscopy program.
Insurance coverage and patient costs
Insurance coverage for a preventive colonoscopy is strong, but it has edges. Most surprise bills come from one of four situations: an out-of-network provider, a grandfathered plan, a polyp removal under Medicare, or a visit coded as diagnostic instead of preventive.
Private insurance under the Affordable Care Act
Most non-grandfathered plans must cover screenings that the USPSTF grades A or B without a copay, coinsurance or deductible when you use in-network providers. In 2015, federal officials clarified that plans cannot charge patients for anesthesia during a screening colonoscopy (KFF Health News).
Removing a polyp during a screening colonoscopy counts as part of the screening, so plans cannot add cost sharing for it (U.S. Department of Labor FAQ Part XII, February 20, 2013).
Federal guidance issued January 10, 2022 also says plans may not charge cost sharing for a colonoscopy that follows a positive stool test. That rule applies to plan years starting on or after May 31, 2022 (U.S. Department of Labor FAQ Part 51).
Medicare
If your provider accepts assignment, Medicare Part B pays the full cost of a screening colonoscopy once every 10 years for average-risk patients, or every 24 months for high-risk patients (Medicare.gov). A follow-up colonoscopy after a positive Medicare-covered stool test also counts as screening.
The catch is polyp removal. If the doctor removes a polyp or takes a biopsy, you pay 15% of the Medicare-approved amount for the doctor and 15% for the facility. The Part B deductible does not apply. That coinsurance drops to 10% from 2027 through 2029 and goes away in 2030, as the Texas Medical Association explains.
Texas law
Texas requires state-regulated health plans to cover colorectal cancer screening for adults 45 and older at normal risk, including a follow-up colonoscopy when initial results are abnormal (Texas Insurance Code Chapter 1363). Many large employers self-fund their plans, and those plans follow federal rules instead of state mandates. Your HR or benefits team can tell you which kind you have.
When a screening becomes diagnostic
If you have symptoms like bleeding, a change in bowel habits or abdominal pain, your colonoscopy is usually billed as diagnostic. Diagnostic exams fall under your regular deductible and coinsurance. A personal history of polyps can also change how the visit is coded. Ask before you book.
Houston prices and national benchmarks
Published Houston colonoscopy prices vary more than tenfold. The spread comes from what each price includes and whether it is a list charge or an amount someone actually pays.
| Source (accessed October 15, 2026) | Price | What it covers |
|---|---|---|
| National self-pay booking service, Houston listing | $1,150 | Physician, facility, anesthesia, polyp removal and pathology; excludes bowel prep (about $30) and sometimes the consult |
| Houston colonoscopy price index, 129 providers | $1,594 median; listed ranges from $700 to $15,700 | Not stated; mixes facility-reported prices and plan fee schedules |
| Texas statewide cash price estimate | $1,199 average | Excludes anesthesia and physician fees |
| Cologuard Plus manufacturer self-pay price | $790 | The test kit and lab analysis |
Total charges versus what you pay
A hospital’s list price, often called the chargemaster rate, is the opening number before any discount. Insurers negotiate lower rates, and your share comes out of that negotiated amount. A cash patient may receive a third number altogether. When you compare prices, make sure you compare the same kind of number.
Why national averages get left out here
We could not verify a current national average for screening colonoscopy against a primary government source, so this guide does not quote one. Medicare’s Procedure Price Lookup lets you check national averages for specific procedure codes yourself.
Why an itemized estimate matters in Houston
Houston’s median household income was $64,813 in 2024 dollars, and 19.9% of residents lived in poverty, according to Census Bureau estimates for 2020 to 2024. Household budgets vary widely across ZIP codes. A $500 difference matters to a lot of families, so a written, itemized estimate is worth the phone call.
Common screening cost questions
What is the self-pay price for a screening colonoscopy at a Houston clinic?
Advertised all-in cash bundles in Houston start around $1,150 and include the physician, facility, anesthesia and pathology. Prices billed separately often run higher. Ask any clinic for a written quote that names every fee included.
How does screening colonoscopy clinic pricing for self-pay patients work?
Some clinics offer one bundled price for the whole visit. Others quote only the physician fee and leave the facility, anesthesia and lab to bill you on their own. Ask whether the price covers biopsies and polyp removal, since those add cost when billed separately.
Does a preventive colonoscopy cost more if polyps are found?
With most private plans, no. Federal guidance treats polyp removal during a screening as part of the screening. With traditional Medicare, yes: in 2026 you pay 15% of the approved amount for the doctor and the facility. Cash patients should confirm that polypectomy and pathology are part of the quoted price.
Is a colonoscopy after a positive Cologuard or FIT test free?
For most private plans with plan years starting on or after May 31, 2022, and for Medicare, the follow-up colonoscopy counts as screening with no cost sharing. Medicare’s polyp-removal coinsurance can still apply. Confirm with your plan first.
Can I use my HSA or FSA?
Yes. Colonoscopy and stool tests are qualified medical expenses, and you can pay for them with HSA or FSA funds.
Requesting a colon screening estimate
A good estimate takes two phone calls: one to your insurance company and one to our office. Have your insurance card ready.
- Call the member services number on your card. Ask whether a screening colonoscopy is covered as preventive care with no cost sharing.
- Ask about these procedure codes: 45378 (diagnostic colonoscopy), G0121 (Medicare screening, average risk), 45380 (colonoscopy with biopsy), 45385 (polyp removal by snare) and 88305 (pathology).
- Ask whether polyp removal, pathology and anesthesia carry cost sharing on your plan.
- Ask whether your plan needs a referral or prior authorization.
- Call our office at 281-945-5190. Our staff will verify your benefits before you are scheduled.
- Ask for a written estimate that lists the physician, facility, anesthesia and pathology fees separately.
If you will pay cash, ask the same questions and request a written self-pay quote. Then review our colonoscopy preparation guide so you know what to buy and when to start.
