Important: These are cost estimates only — not a quote and not medical advice.
The prices on this page are self-pay rates, drawn from federal Transparency in Coverage machine-readable files (CPT 45385 — Colonoscopy with removal of polyps by snare). They represent what a patient might pay without insurance.
Your actual cost depends on: your specific insurance plan, your remaining deductible, your coinsurance percentage, whether you have met your out-of-pocket maximum, whether the facility and provider are both in-network, and any separate anesthesia or implant fees billed independently.
This page does not constitute medical advice. Whether you need this procedure, and which approach is right for you, is a decision to make with a licensed healthcare provider.

How to read this data
Negotiated Rate
The discounted price an insurer has agreed to pay a specific provider. Most insured patients' bills are calculated from this number, not the higher list price hospitals publish separately.
P5, Median, P95
P5 is the rate at the 5th percentile (low end), Median is the middle value, and P95 is the 95th percentile (high end). This range shows how much the same visit can vary between providers.
What this does not tell you
These rates do not tell you what you personally will pay out of pocket. That depends on your specific plan, how much of your deductible you have already met, your coinsurance rate, and whether the provider is in your network. Call your insurer's member line to get your exact estimate.
Why Colonoscopy Polyp Removal Visit Costs Vary Across Washington
Washington's healthcare costs run approximately 10% above national averages, driven by the state's concentration of major medical centers and higher labor costs in metropolitan areas. The geographic spread from dense urban centers like Seattle-Tacoma to remote rural counties creates dramatic cost variations for specialized procedures.
Urban vs. Rural Provider Availability
Seattle and Spokane metropolitan areas host the majority of Washington's gastroenterology specialists, creating higher competition and varied pricing within these markets. Rural counties often require patients to travel significant distances, though some smaller cities offer competitive rates due to lower overhead expenses.
Facility Type and Overhead Costs
Major health systems like UW Medicine, MultiCare, and Providence typically charge higher rates for hospital-based procedures compared to independent ambulatory surgery centers throughout Washington. These systems often provide more complex care capabilities but pass along higher facility fees to patients and insurers.
Insurance Market Competition in Washington
Washington's four major insurers - Premera, Regence, Kaiser, and UnitedHealthcare - maintain relatively competitive markets that help moderate negotiated rates for specialist procedures. The state's active insurance commissioner and rate review process provides additional oversight that can influence pricing trends across the market.
Physician Supply and Demand in Washington
With 4,541 active providers offering colonoscopy services, Washington maintains adequate specialist availability relative to its population, particularly in urban corridors. This healthy supply helps moderate pricing pressure and reduces wait times, though rural areas may still experience access challenges requiring longer travel distances.
