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 45380 — Colonoscopy with biopsy). 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 with Biopsy Visit Costs Vary Across Washington
Healthcare costs in Washington run approximately 10% above national averages, driven by the state's high cost of living, particularly in the Seattle metropolitan area. The concentration of major health systems and academic medical centers in urban areas creates pricing disparities between metropolitan and rural regions.
Urban vs. Rural Provider Availability
The Seattle-Tacoma-Bellevue metro area contains the majority of Washington's gastroenterology specialists, while rural areas east of the Cascades have limited access to colonoscopy services. This geographic concentration forces rural patients to travel for care, often to higher-cost urban facilities.
Facility Type and Overhead Costs
Hospital-owned outpatient clinics typically charge 20-40% more than independent gastroenterology centers due to facility fees and administrative overhead. Major health systems like UW Medicine, Swedish, and Virginia Mason dominate the Seattle market, while smaller independent practices are more common in secondary cities.
Insurance Market Competition in Washington
Strong competition among Premera, Regence, Kaiser, and UnitedHealthcare has helped moderate rate increases compared to less competitive markets. However, Kaiser's integrated model and narrow network approach can limit provider choice while potentially reducing costs for members.
Physician Supply and Demand in Washington
With over 4,600 providers offering colonoscopy with biopsy services statewide, Washington has relatively good specialist availability compared to national averages. This adequate supply helps moderate pricing pressure, though wait times for routine procedures can still extend several weeks in popular practice locations.
