A message from Blue Cross Blue Shield of Massachusetts:
Mount Sinai Health has notified us that they plan to leave the Blue Cross Blue Shield network, which would be effective on January 1, 2026 for professional providers, and on March 1, 2026 for facilities due to the NY State Law: 60-Day Cooling-Off period. If this happens, they will be considered out-of-network. We’re actively negotiating with Mount Sinai Health and hope to reach an agreement. If we do, we’ll send you another email to let you know that they will stay in our network.
