How to use these numbers: Published hospital rates are estimates of what care costs under federal Hospital Price Transparency rules (45 CFR § 180.50), not binding quotes. Always confirm the exact CPT code (45378) and whether facility + professional (radiologist/pathologist/anesthesia) fees are billed separately.
