Breaking up is hard to do—especially when the split isn’t on your terms. On Jan. 1, 2026, New Yorkers enrolled in Anthem Blue Cross Blue Shield health plans received news that their insurer had broken up with Mount Sinai, one of the largest hospital systems in the US. In an open letter, Anthem said it failed to reach a contract in negotiations with the provider network. As a result, members seeing any of Mount Sinai’s roughly 9,000 doctors no longer have insurance coverage for these providers. Coverage for the health system’s hospitals, outpatient centers, and other facilities is set to end on March 1, though experts say the two sides could still reach an agreement before then, or further down the road. This isn’t the first time Mount Sinai has dropped coverage for patients enrolled in certain health plans, and these occurrences aren’t limited to New York. Eighteen percent of non-federal hospitals across the US fought publicly with an insurance company between June 2021 and May 2025, while 8% of these hospitals went out of network with an insurer, at least temporarily, according to research from Jason Buxbaum, a health policy researcher with Brown University’s School of Health. These disruptions are a reflection of the current healthcare market, industry experts told HR Brew.

Strategic communication is key, though, when workers are affected by such disruptions, they added. For more on what’s driving some providers out of health plan networks, keep reading here.—CV |
