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.

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.
