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 California
California's healthcare costs run approximately 18% above national averages, driven by the state's high cost of living, strict regulatory environment, and concentrated urban markets. The state's vast geography creates stark disparities between resource-rich metropolitan areas and underserved rural regions stretching from the Central Valley to the far north.
Urban vs. Rural Provider Availability
Metropolitan areas like Los Angeles, San Francisco, and San Diego feature dense concentrations of gastroenterologists, while rural counties in the Central Valley and northern California face significant specialist shortages. Patients in remote areas often travel 100+ miles to reach qualified providers, creating additional costs for lodging and time off work. Telemedicine consultation helps bridge some gaps, though the procedures themselves require in-person visits.
Facility Type and Overhead Costs
Large health systems like Kaiser Permanente, Sutter Health, and Dignity Health dominate California's market, operating both hospitals and outpatient centers with varying cost structures. Independent ambulatory surgery centers typically offer lower facility fees than hospital outpatient departments, though availability varies by region. California's high real estate costs, strict seismic requirements, and regulatory compliance significantly impact facility overhead expenses.
Insurance Market Competition in California
Anthem, Kaiser, and UHC control substantial market share across California, though regional variations exist with Health Net stronger in Southern California and Blue Shield more prevalent in Northern regions. Kaiser's integrated model creates different pricing dynamics compared to traditional insurers, while consolidated markets in some counties limit competitive pressure on negotiated rates. California's state exchange adds complexity with numerous plan options and narrow networks.
Physician Supply and Demand in California
With over 12,000 providers performing colonoscopies statewide, California maintains adequate overall supply, though distribution heavily favors coastal urban areas over inland regions. The state's aging population and expanded insurance coverage through Medicaid increase demand for screening procedures, potentially creating scheduling delays in high-demand markets. Physician practice costs including malpractice insurance, real estate, and regulatory compliance contribute to higher procedure fees compared to other states.
