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.

Where this data comes from & what CPT 45378 covers

Data source: Cost figures are derived from UnitedHealthcare Transparency in Coverage machine-readable files for CPT code 45378 (Diagnostic colonoscopy, flexible), as mandated by the CMS Price Transparency Rule.

What CPT 45378 covers: the provider's professional fee for colonoscopy. It does not include facility/hospital fees, anesthesia, pre-operative imaging, post-operative care, or any add-on codes billed separately.

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.
