Protecting Access and Affordability for Our Members
Mount Sinai Hospitals and Doctors Have Left Our Network.
Here’s What You Need to Know.
UPDATE (March 17, 2026):
Despite our best efforts to keep Mount Sinai doctors and hospitals in our network, Mount Sinai executives refused our offers to do so. Effective March 4, 2026, Mount Sinai hospitals have joined their physicians, specialists, and allied healthcare professionals as out-of-network providers.
Please see below for more detail and continue to check this website for further updates.
Why Can’t Anthem Reach an Agreement with Mount Sinai?
We have already reached agreement on most aspects of a new contract that would return Mount Sinai to our network. Importantly, we have agreed on reasonable price increases that will keep costs as low as possible for patients and their employers. In fact, we had a finalized agreement ready for Mount Sinai’s executives to sign weeks ago.
But Mount Sinai’s executives refused the agreement. Instead, they now insist on removing standard billing protections and network stability for patients. Specifically, Mount Sinai’s administration wants to:
- Submit bills without standard checks to ensure accurate charges;
- Block routine reviews that verify healthcare claims;
- Allow hospital bills without basic care details;
- Permit claims submissions years after care is delivered;
- Require payment even if standard authorization steps were not followed;
- Limit employers’ ability to design affordable health plans for their workers;
- Allow the hospital system to leave the network at any time without warning.
Such provisions are not in place with any other health system in New York because they would remove fundamental accountability in the claims and payment process. Without these long-standing checks in the system, patients and their employers would be exposed to overbilling, unnecessary out of pocket costs, duplicate charges, and sudden disruptions in their care provider networks.
We're Protecting Your Access to Care
- Our network includes every other hospital system in New York, giving you many in-network alternatives. We recommend scheduling or rescheduling elective care at one of our in-network care providers.
- We have extended our Continuity of Care protections so patients in treatment for serious health conditions continue to receive in-network coverage for care at Mount Sinai’s doctors and hospitals. See below for important information in How We're Helping.
- Many physicians who admit patients to Mount Sinai contracted directly with Anthem to avoid patient care disruption. See below in Frequently Asked Questions for a current list or you may contact your doctor’s office to find out if your physician is among them.
- Anthem covers emergency care under your policy benefits at in-network cost shares, no matter where you go.
- We continue working to reach an agreement with Mount Sinai and will continue updating this page.
We're Standing Up for Lower Healthcare Costs and Proper Oversight
New Yorkers already face a healthcare cost crisis. The good news is that we’ve already agreed with Mount Sinai on reasonable price increases that will help keep healthcare costs down. But we won’t agree to contract terms that would severely undercut accountability, transparency, and billing accuracy. Mount Sinai executives are asking to bill patients as they wish without checks to prevent erroneous charges.
Our goal is simple: to lower your healthcare costs.
Direct Contracting for Care Providers
If you’re a Mount Sinai affiliated doctor, specialist, or allied healthcare professional who would like to keep your in-network status with us, we may be able to contract with you directly.
Setting the Record Straight on What Mount Sinai’s Demands Mean for Patients
Mount Sinai has been sharing misleading information about our work to keep them in our network—it’s time to clear things up.
Our Members are Our First Priority – How We’re Helping
Every other hospital system in the Tri-State area participates in our network, which means our members still have many great options for in-network care. Whether it’s a serious medical condition, an elective procedure, or finding a new primary care physician, our member service team is prepared to help you.
- We recently extended protections for patients undergoing treatment at Mount Sinai. Anthem will continue to provide in-network coverage under Continuity of Care guidelines. Examples of conditions that qualify for Continuity of Care include cancer, pregnancy, ongoing treatments for serious and complex conditions, including mental health and substance use disorders, urgent surgeries that are already scheduled, hospitalization, or treatment for terminal illness.
- If you’re not currently in treatment for a serious condition, we recommend scheduling or rescheduling elective care at one of our many high-quality in-network health systems. Every other hospital system in the Tri-State area participates in our network. For help, log in to Anthem.com or the Sydney Health® app or call our member service center.
We have worked closely with our other network partners—especially primary care providers—to ensure access to appointments. Our members still have broad access to high quality care from every other major health system in New York, including:
