Following Nolte v. Cedars-Sinai Medical Center (2015) 236 Cal.App.4th 1401, this decision holds that it is not an unfair or unlawful business practice for a hospital not to affirmatively disclose, prior to treatment, that it will charge an emergency room charge to patients using the emergency room.  Extensive state and federal statutes and regulations require specific sorts of disclosures of hospital charges, but not this one which is antithetical to federal law which requires emergency rooms to treat anyone who shows up demanding treatment–and not to discourage those patients by threatening high charges for their care.  Because there is no duty to disclose the charge, plaintiff also could not establish that the hospital violated the CLRA, Civ. Code 1770(a)(5) or (a)(14).
