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 45378 — Diagnostic colonoscopy, flexible). 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 Visit Costs Vary Across Washington
Washington's healthcare costs run approximately 10% above national averages, reflecting the state's high cost of living in metropolitan areas and the concentration of academic medical centers. The Cascade Mountains create a natural divide between the densely served Puget Sound region and more sparsely populated eastern counties, leading to significant access and pricing disparities.
Urban vs. Rural Provider Availability
Seattle-Tacoma metro area contains the majority of Washington's specialists, while rural counties east of the Cascades often require patients to travel hours for specialized care. This geographic concentration drives up costs in urban areas due to high overhead while creating access challenges and potentially higher travel costs for rural patients.
Facility Type and Overhead Costs
Hospital-based outpatient clinics affiliated with major systems like UW Medicine, MultiCare, and Providence typically charge facility fees that can double the cost of routine visits compared to independent practices. Academic medical centers command premium pricing due to their teaching hospital status and research activities, while community-based practices often offer more competitive rates.
Insurance Market Competition in Washington
Washington's insurance market shows moderate competition with Premera Blue Cross, Regence BlueShield, Kaiser Permanente, and UnitedHealthcare holding significant market share. This competitive environment helps keep negotiated rates reasonable, though consolidation among health systems has given large providers more leverage in contract negotiations with insurers.
Physician Supply and Demand in Washington
With over 5,500 active Colonoscopy providers serving the state's 7.7 million residents, Washington shows adequate specialist availability in urban areas but significant shortages in rural regions. This supply imbalance contributes to longer wait times and potentially higher costs in underserved areas, particularly in counties with fewer than 50,000 residents.
