Different proposals -- including one for so-called "baseball arbitration" ? aim to address insurance-payment issues that arise when patients are treated at out-of-network hospitals or even by out-of-network doctors at in-network hospitals. "Baseball arbitration," in which hospitals and insurers would submit offers to an arbitrator, has been proposed as one possible solution. For example, if an out-of-network hospital charged a patient $2,000 for a procedure and the patient's insurer offered $1,000, the arbitrator could choose one price over the other. It's one of a variety of ideas that have emerged as legislators have discussed how to address the sticker shock from New Jersey's high out-of-network medical bills.
