[…] As David pointed out, there’s also likely to be frustration for patients as providers move in and out of networks. This can happen regardless of the size of a network, but if networks are purposely kept small, it’s more likely to happen. Patients tend to be wary of having to find new doctors, and having to do so simply because of network changes isn’t likely to make people happy. Hopefully the idea of narrow provider networks won’t become a widespread trend with employers, medical providers, or health insurance carriers.
