Colon polyp removal during a routine screening colonoscopy is free under most insurance plans, with no copay or deductible. When insurance doesn’t cover the procedure, or when the colonoscopy is diagnostic rather than preventive, the total bill typically ranges from $1,200 to over $16,000 depending on your location, facility type, and how many polyps are removed. Nasal and uterine polyp removal carry their own price ranges, often higher than a standard colonoscopy polypectomy.
Colon Polyp Removal: What You’ll Pay
The statewide average total charge for a colonoscopy with polyp removal in New Hampshire, one of the few states that publishes transparent pricing, is $8,313 before any discounts. The actual amount patients pay after uninsured discounts ranges from about $1,200 at the lowest-cost facilities to over $16,400 at the most expensive. These numbers reflect the full procedure: facility fee, physician fee, anesthesia, and pathology.
That wide range isn’t unusual. Where you have the procedure done is one of the biggest cost drivers. Hospital outpatient departments charge significantly more than ambulatory surgery centers (ASCs) or office-based settings. A Blue Cross Blue Shield analysis found that hospital outpatient prices for common procedures were sometimes five times higher than the same procedure at an ASC. If you’re paying out of pocket, calling both types of facilities for quotes can save thousands of dollars.
When Insurance Covers It Completely
Under the Affordable Care Act, screening colonoscopies recommended by the U.S. Preventive Services Task Force are classified as preventive care. That means most private insurance plans must cover them with zero cost-sharing: no copay, no coinsurance, no deductible. The key detail many people don’t realize is that polyp removal during a screening colonoscopy is also fully covered. Federal guidance from the Centers for Medicare & Medicaid Services explicitly states that polyp removal is “an integral part of a colonoscopy,” so insurers cannot charge you extra when a polyp is found and removed during what was scheduled as a screening.
This protection applies to the standard screening schedule: starting at age 45 for average-risk adults, repeated every 10 years. Medicare also covers screening colonoscopies, though beneficiaries on Original Medicare may still owe a percentage of the anesthesia fee in some situations.
The coverage changes if the colonoscopy is classified as diagnostic. If you’re having the procedure because of symptoms like bleeding, changes in bowel habits, or a follow-up to a previous finding, your plan may apply your deductible and coinsurance. The same procedure can cost you nothing or several thousand dollars depending on how it’s coded.
The Hidden Bills: Anesthesia, Pathology, and Lab Fees
Even when you expect coverage, surprise charges can appear from providers who bill separately. A typical colonoscopy with polypectomy generates at least three separate bills: the gastroenterologist’s professional fee, the facility fee, and the anesthesia fee. Anesthesia for a lower intestinal endoscopy is billed under its own code and can add $500 to $1,500 or more depending on the duration and your location.
After a polyp is removed, it goes to a pathology lab to be examined under a microscope for precancerous or cancerous cells. Pathology processing fees vary widely. Academic medical centers may charge $18 to $35 per slide for tissue processing and staining, but the total pathology bill you see will include the pathologist’s professional interpretation fee on top of lab costs. Expect the pathology portion to add $100 to $500 to the total, though it can run higher at hospital-based labs. If your screening colonoscopy is covered preventively, these associated pathology charges should also be covered, but it’s worth confirming with your insurer beforehand.
Nasal Polyp Removal Costs
Surgical removal of nasal polyps through endoscopic sinus surgery is a significantly more expensive procedure. Published studies report typical costs between $8,000 and $13,000, though a large database analysis of real-world claims found the average total medical cost was closer to $14,700. Patients who experienced complications saw costs climb to roughly $23,600.
Nasal polyp surgery is almost always classified as medically necessary rather than elective, so insurance typically covers a substantial portion. Your out-of-pocket share depends on your deductible and coinsurance. For someone with a $2,000 deductible and 20% coinsurance on a $14,700 procedure, the personal cost would be around $4,500. Some insurers require you to try steroid nasal sprays or oral steroids before approving surgery, so the path to coverage may involve documenting that conservative treatments failed.
Uterine Polyp Removal Costs
Uterine polyps are removed through hysteroscopy, a procedure where a small camera is inserted through the cervix. The cost depends heavily on whether the procedure happens in a doctor’s office or an operating room. Office-based hysteroscopy costs roughly $1,356 total, since it eliminates anesthesia and hospital facility fees. The same procedure in an operating room jumps to about $4,946 per patient, with the difference driven almost entirely by the anesthesia fee (around $1,190) and the hospital facility fee (around $2,400).
Not every patient is a candidate for office-based removal. About 42% of patients who start with an office hysteroscopy end up needing the operating room procedure anyway, which means paying for both. Even accounting for that, the office-first approach saves an average of about $1,500 per patient compared to sending everyone directly to the operating room. If your gynecologist offers in-office hysteroscopy and your polyp is small, it’s worth asking whether that’s an option.
How to Reduce Your Cost
If you’re uninsured or facing a high deductible, a few strategies can meaningfully lower the bill. Choosing an ambulatory surgery center over a hospital outpatient department is the single biggest lever, potentially cutting the facility fee by half or more. Many facilities offer cash-pay or prompt-pay discounts of 20% to 40% for uninsured patients if you ask before the procedure.
For colon polyps specifically, make sure your colonoscopy is scheduled and coded as a screening rather than diagnostic whenever clinically appropriate. If your doctor orders it as a screening but the facility recodes it after finding polyps, you have grounds to appeal that with your insurer under ACA rules. Keep a copy of the original order.
Ask in advance whether all providers involved, including the anesthesiologist and pathology lab, are in your insurance network. Out-of-network anesthesiologists have historically been one of the most common sources of surprise medical bills, though the No Surprises Act now limits what you can be billed for out-of-network emergency and ancillary services at in-network facilities.
