The Mount Sinai Health System has enacted a policy that stops new appointments for patients on certain government-subsidized insurance plans. This change, which took effect August 1, targets individuals enrolled in Medicaid, Child Health Plus, or Essential Plans via EmblemHealth and Fidelis Care. The restriction also extends to certain Medicare Advantage products.

Internal documentation suggests the hospital system is reviewing its practice panels based on operational priorities. Patients who have not visited a Mount Sinai provider since July 31, 2025, are now classified as new patients under these terms. Exceptions exist for specific cases such as transplant, obstetrics, and pediatric care.

The health system originally posted this policy on its public website but removed the information after inquiries were made regarding the scope of the decision. Spokespeople for the system indicate they are evaluating their participation in specific health plans to ensure long-term sustainability.

This move has created friction for existing patients who rely on these providers. Reports indicate that even long-term patients attempting to book new appointments for specialty services have faced rejection due to these updated insurance criteria. EmblemHealth officials have stated they were unaware of the change prior to the inquiry and are currently in the middle of contract negotiations with the provider.
