In the U.S., polyp removal surgery ranges from about $1,500 to $15,000+, depending on type, setting, and insurance.
Price depends on three levers: the kind of polyp, where it’s done (hospital outpatient department vs. ambulatory surgery center vs. office), and how your insurance classifies the visit. This guide breaks down typical cash prices, what insurance pays, and the line items that appear on a bill. You’ll also see smart ways to lower costs without cutting care.
What Drives The Cost Of Removing Polyps
“Polyp removal” isn’t a single operation. A small growth in the colon is usually removed during a colonoscopy with a snare. A fleshy lesion inside the uterus is often taken out with a hysteroscope. Tissue growths in the nose are handled with endoscopic sinus surgery. Each route uses different rooms, tools, time, and staff—so prices vary widely.
Setting And Equipment
Hospital outpatient departments tend to bill the highest facility fees. Ambulatory surgery centers (ASCs) are usually lower. In-office procedures can be far cheaper because there’s no operating-room or recovery-room charge. Add specialized tools—snares, scopes, microdebriders—and the total climbs.
Insurance Labeling
Insurers sort procedures as preventive, diagnostic, or therapeutic. For colorectal screening, a colonoscopy that starts preventive can switch to diagnostic the moment a polyp is removed. That switch changes what you pay (more on this below, with rules that affect your bill today and in the next few years).
Size, Number, And Location
Multiple or hard-to-reach lesions take longer and may require advanced techniques or extra instruments. More time and tools usually mean higher facility and anesthesia fees.
Typical Prices By Procedure Type (Quick Scan)
The ranges below reflect common cash prices from public rate tools and price-transparent centers. Local markets vary, so use these as orientation, not a quote.
| Polyp Type | Common Procedure | Typical Cash Price Range (USD) |
|---|---|---|
| Colon/Rectum | Colonoscopy with polypectomy | $1,400–$4,800+ (state averages and market quotes) |
| Nasal/Sinus | Endoscopic sinus surgery (polyp removal) | $8,000–$13,000+ (broader cases can exceed this) |
| Uterus (Intrauterine) | Hysteroscopic polypectomy | $4,000–$7,000+ (office vs. ASC vs. hospital changes this) |
| Cervix | In-office cervical polypectomy | $200–$600 (simple cases in clinic) |
Close Variation: What Does Polyp Removal Surgery Cost, Really?
Let’s break down real-world totals by the common categories, then show how insurance shifts the final bill.
Colon: Polyp Removal During A Colonoscopy
For people paying cash, statewide averages for the polypectomy portion cluster around the low-thousands, while the all-in colonoscopy total (visit, facility, anesthesia, pathology) can land anywhere from roughly $1,500 to nearly $5,000 or more depending on the market and venue. Hospital outpatient departments tend to sit at the higher end; ASCs are often lower.
How Coverage Changes Your Share
Screening colonoscopies are usually fully covered. If a lesion is removed, some plans reclassify the event as diagnostic, which triggers coinsurance. Medicare lays out a schedule that reduces the coinsurance for polyp removal during a screening visit: 15% for 2023–2026, 10% for 2027–2029, and $0 starting in 2030. See the official policy details on Medicare colonoscopy coverage and CMS’ phased coinsurance reduction (PDF). Linking your pre-op paperwork to this rule helps avoid surprises if your screening converts to removal mid-procedure.
Nasal: Endoscopic Sinus Surgery For Polyps
When polyps fill sinus passages or resist sprays, surgeons use endoscopic tools to open drainage pathways and remove diseased tissue. Published data place typical episodes in the high four to low five figures. The range is broad because some cases need several sinus areas opened, image-guidance, or revision work. Post-op debridements and medications add to total spend.
Uterus: Hysteroscopic Polyp Removal
Intrauterine lesions are commonly handled via hysteroscopy—often as an outpatient event. All-in cash bundles from transparent centers and marketplace quotes often fall between the mid-four and low-five figures, with the low end representing streamlined office or ASC cases and the higher end reflecting hospital pricing or add-on procedures (e.g., simultaneous fibroid resection).
Cervix: In-Office Removal
Many cervical lesions are removed in clinic with local measures. Bills here look nothing like an OR case: a brief visit, a small pathology fee, and minimal supplies. That difference in site of care is why the low hundreds is possible.
What’s On The Bill (And Why)
Even simple cases produce several separate lines. Understanding each one helps you ask the right questions and compare apples to apples when shopping.
| Bill Component | What It Covers | Typical Range |
|---|---|---|
| Facility Fee | OR/procedure room, nursing, equipment, recovery | Hundreds to several thousand; hospitals usually higher than ASCs |
| Physician Fee | Surgeon’s professional service (removal technique and complexity) | Low hundreds to a few thousand, code-dependent |
| Anesthesia | CRNA/MD time and drugs (MAC, general, or none) | ~$200–$1,000+ based on time and setting |
| Pathology | Lab processing and pathologist’s review of the specimen | ~$100–$300+ depending on tissue type and number of samples |
| Imaging/Guidance | Image-guided tools in sinus cases; sometimes separate | Varies widely; ask if billed by the facility |
Insurance Rules That Change The Final Number
Screening That Becomes Removal
For colorectal screening, many plans pay the full visit when nothing is found. When tissue is removed, your plan may treat it as diagnostic. With Medicare, the coinsurance tied to that switch is shrinking on a national schedule set by CMS, with a full waiver beginning in 2030. If you’re not on Medicare, ask your plan how it treats removal during a screening visit and whether coinsurance kicks in that day.
Deductibles, Coinsurance, And Networks
If you haven’t met your deductible, facility and professional fees can hit your wallet before coinsurance even applies. A single out-of-network provider (anesthesia, pathology, facility) can turn a reasonable estimate into a sting. Confirm every party is in-network, not just the surgeon.
Prior Authorization And Coding
Some plans want prior authorization for sinus or uterine cases. If a pre-authorization was given for one code but the operative note supports a different code, your claim might be reworked at a higher or lower rate. Ask the office which CPT codes they expect to use and what could change once they’re in the room.
Ways To Lower The Cost Without Cutting Care
Pick The Right Site Of Care
When clinically appropriate, an ASC or office can save thousands compared with a hospital outpatient department. Ask your surgeon if your case qualifies for a lower-cost site and whether the plan allows it.
Request A Single, Written Estimate
Ask for a bundled quote that names the facility, surgeon, anesthesia, and pathology. A one-pager with CPT codes and an itemized list makes it easy to compare. If your plan offers a price-match or shopping incentive, send that document.
Ask About In-Office Options
Some uterine or cervical cases can be handled in clinic with oral meds and local measures. If you’re a fit for an in-office approach, the savings can be large and recovery is often quicker.
Use Official Rules To Your Advantage
For colorectal screening, point the billing team to the federal rule that phases down coinsurance when tissue is removed during a screening visit. The current details live on the Medicare colonoscopy coverage page and in CMS’ policy update (PDF). Getting the correct modifier on the claim keeps your out-of-pocket aligned with the law as that coinsurance drops over time.
Realistic Scenarios And What You’d Pay
Screening Colonoscopy That Finds A Small Lesion
You booked a routine screening with an in-network gastroenterologist at an ASC. A small lesion is removed with a snare. If you’re on Medicare today, the coinsurance portion tied to the removal is 15%; it drops to 10% in 2027 and goes to zero in 2030. Commercial plans vary; many treat this as diagnostic the moment removal occurs, so deductibles and coinsurance could apply even at an ASC.
Chronic Sinus Polyps With Multiple Blocked Areas
You’ve tried steroid sprays and rinses without relief. Endoscopic surgery opens the blocked sinus pathways and clears diseased tissue. Because this uses operating-room time, specialized instruments, and post-op visits, totals usually land in the five-figure zone. Picking an ASC, confirming in-network anesthesia, and clarifying whether image-guidance carries a separate fee are the biggest levers.
Intrauterine Lesion Found On Ultrasound
Your gynecologist offers removal with a hysteroscope. If the plan allows an ASC or office setting, that choice can keep the bill near the lower end of the typical range. If you’re paying cash, ask for a bundled rate that includes the scope, anesthesia plan, and pathology.
How To Get A Solid Estimate
- Ask for CPT codes the team expects to use. Common examples: colon snare removal (e.g., endoscopic polypectomy codes), sinus surgery codes for each sinus opened, and hysteroscopic removal codes for uterine tissue.
- Confirm place of service. The same CPT code costs more at a hospital outpatient department than at an ASC or office.
- Get all four players in writing: facility, surgeon, anesthesia, pathology. Verify network status for each.
- If you’re screening for colorectal cancer, point billing to the current Medicare framework that reduces coinsurance when removal happens during a screening visit.
- Use a few local quotes. Many centers post self-pay bundles; send the lowest credible quote to your preferred site and ask if they can match it.
When To Choose A Higher-Cost Setting
Cost isn’t the only variable. Certain medical histories, bleeding risks, difficult anatomy, or the need for advanced equipment make hospitals the safer choice. That trade-off is worth it. Ask your surgeon to explain the benefits of a higher-acuity setting if they recommend one.
Takeaways You Can Act On Today
- For colorectal screening, know that coinsurance tied to removal during a screening visit is shrinking on a federal schedule and will be $0 in 2030. That one detail can change your out-of-pocket.
- The site of care matters. If appropriate, an ASC or office can trim thousands without changing the clinical plan.
- Pathology, anesthesia, and facility fees are the swing items. Get them listed before the day of care.
- Real, written estimates with CPT codes make comparison shopping straightforward and keep billing aligned with what was promised.
