Mount Sinai curbs new patient appointments for select public-insurance plans

Mount Sinai Health System temporarily stopped accepting new patients enrolled in certain government-subsidized plans (Medicaid, Child Health Plus, and Fidelis/EmblemHealth plans, including Fidelis plans via the ACA marketplace or Medicare Advantage) effective Aug. 1; the cutoff applied to anyone not seen by Mount Sinai since July 31, 2025, with exceptions for transplant, obstetrics and pediatrics. After inquiries from POLITICO, the hospital removed the notice from its site, saying the policy affects only new patients and reflects routine plan reviews and capacity. Insurers and patients have expressed concern about access to care amid the confusion.
