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 California
California's healthcare costs run approximately 18% above the national average, driven by the state's high cost of living, stringent regulatory environment, and concentration of premium healthcare facilities in major metropolitan areas. The state's diverse geography creates significant cost variations between coastal urban centers and inland rural communities.
Urban vs. Rural Provider Availability
The San Francisco Bay Area and greater Los Angeles region concentrate the majority of California's gastroenterology specialists, creating premium pricing in these markets while rural areas like the Central Valley and far northern counties face provider shortages. Patients in underserved regions often travel significant distances for specialized procedures, adding transportation costs to their total healthcare expense. This supply-demand imbalance contributes to the wide cost variations seen across the state.
Facility Type and Overhead Costs
California's major health systems including Kaiser Permanente, Sutter Health, and Cedars-Sinai operate extensive networks of hospital-based outpatient centers that typically charge higher facility fees than independent practices. Academic medical centers like UCSF and UCLA command premium rates due to their research missions and complex case mix. Independent ambulatory surgery centers often provide the most cost-effective option for routine procedures.
Insurance Market Competition in California
The dominance of Anthem Blue Cross, Kaiser Permanente, and UnitedHealthcare creates a moderately competitive but consolidated market where negotiated rates vary significantly by insurer and region. Kaiser's integrated delivery model often results in different pricing structures compared to traditional fee-for-service arrangements. Regional insurers like Blue Shield of California and Health Net add competitive pressure in select markets.
Physician Supply and Demand in California
With over 9,290 providers offering Colonoscopy Polyp Removal procedures, California maintains a relatively robust supply of qualified specialists, though distribution favors urban coastal areas over inland regions. This supply level generally supports reasonable access and competitive pricing in major metropolitan areas. Wait times tend to be shorter in areas with higher provider density, while rural regions may experience longer scheduling delays that can affect both cost and care coordination.
