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 Illinois
Illinois healthcare costs run approximately 10% above national averages, driven by the concentration of high-cost academic medical centers in Chicago and limited rural provider options. The state's economy supports higher physician salaries while regulatory requirements add administrative overhead that gets passed to patients.
Urban vs. Rural Provider Availability
The Chicago metropolitan area contains roughly 70% of Illinois gastroenterologists, creating significant access challenges for residents in southern and central Illinois counties. Rural patients often face 100+ mile drives to reach subspecialty care, sometimes opting for higher-cost emergency department visits when complications arise. This geographic maldistribution allows urban providers to command premium pricing while rural facilities struggle with volume.
Facility Type and Overhead Costs
Major health systems like Northwestern Medicine, Rush University Medical Center, and University of Chicago Medicine dominate the Illinois market with hospital-based practices that typically charge facility fees. Independent gastroenterology groups offer more competitive pricing but may have limited locations outside major metropolitan areas. Academic medical centers command the highest rates due to teaching hospital overhead and research missions.
Insurance Market Competition in Illinois
Blue Cross Blue Shield of Illinois maintains the largest market share, followed by UnitedHealthcare and Aetna, creating moderate competition that helps contain some cost growth. The state's insurance market is relatively concentrated compared to neighboring states, giving major insurers significant negotiating leverage with provider networks. Employer-sponsored plans dominate coverage, with limited individual market options in many counties outside Chicago.
Physician Supply and Demand in Illinois
With 5,408 active providers offering colonoscopy services, Illinois has adequate specialist supply in urban areas but significant shortages in rural regions. The concentration of providers in Chicago and surrounding suburbs creates competitive pricing in those markets while allowing rural practitioners to charge premium rates. Wait times for non-urgent procedures average 2-4 weeks in Chicago but can extend to 6-8 weeks in underserved rural areas.
