What the whole procedure costs
The rate above is the physician’s fee on its own. The facility bills separately, and for most procedures the facility is the larger half of the bill. These are 2026 national Medicare amounts.
Choosing a surgery centre over a hospital saves about $566 on the Medicare allowed amount for colonoscopy with polyp removal. Ask whether your procedure can be done at an ambulatory surgery centre.
This is Medicare's separate payment to the facility on top of the physician's fee. Medicare allowed amounts are not what an uninsured patient is charged, and not a quote. Private plans typically allow more.

What these numbers are
Every figure on this page is a 2026 Medicare allowed amount: the physician line comes from the Physician Fee Schedule adjusted by geographic practice-cost indices, and the facility totals come from the CMS hospital outpatient (OPPS) and ambulatory surgery centre rates. None of them is a hospital chargemaster price, your insurer's contracted rate, or a quote. Anesthesia, pathology, imaging reads and follow-up care are billed under their own codes when they apply, and an inpatient stay is paid a different way again. In Washington the office and hospital physician lines for this CPT differ by $315.28.

Colonoscopy With Polyp Removal and how Washington is priced
Washington divides into a Seattle-area locality and a rest-of-state locality, so Puget Sound's biggest market carries higher geographic adjustments than Spokane, the Tri-Cities, or the coast. The Seattle locality reflects some of the highest wages in the western United States, while everywhere else in the state shares one lower-cost set of factors. An identical procedure is therefore approved at more in Seattle than in Spokane, a two-tier pattern much like Oregon's. Rest-of-state Washington still prices respectably against national averages.
Seattle is the referral capital of the Pacific Northwest, with academic medicine that serves not just Washington but Alaska, Montana, Idaho, and Wyoming through long-standing regional arrangements. Spokane anchors the Inland Northwest, drawing patients from northern Idaho and beyond, while the Olympic Peninsula and southwest coast are comparatively underserved. Rapid consolidation has concentrated much of the state's care into a few large systems.
This procedure: This colonoscopy code means the physician found one or more polyps and removed them using a snare, a thin wire loop that lassoes the polyp and cuts it free, often with cauterizing current. Snare removal is the standard technique for larger polyps and is the step that gives colonoscopy its cancer-preventing power, since removing precancerous polyps stops them from progressing. The patient experience is unchanged from any colonoscopy: prep, IV sedation, a 20 to 45 minute procedure, and same-day discharge.

What Affects the Cost
- –Every removed polyp goes to pathology in its own container, and each container is a separate lab charge.
- –The physician fee for snare polypectomy is the highest of the common colonoscopy codes, above both biopsy (45380) and diagnostic (45378).
- –Facility setting remains the biggest overall cost lever, with hospitals charging far more than endoscopy centers.
- –Separately billed anesthesia adds its own professional fee.
- –Large or complex polyps may require advanced removal techniques or clips to close the site, which can add device and procedure charges.
- –Finding polyps shortens your recommended interval to the next colonoscopy, pulling that future cost closer.
Questions to Ask Before Booking
- 1.If polyps are removed during my screening, will the procedure still be billed with the preventive modifier at no cost share to me?
- 2.What will the pathology lab charge per polyp, and is that lab in network?
- 3.For Medicare: what percentage coinsurance applies to polyp removal during a screening this year?
- 4.If you find a large polyp needing a special technique or clips, how does the cost change?
- 5.How soon will I need my next colonoscopy if polyps are found, and will that one count as screening or surveillance for coverage?
