Additionally, a provider shall not amend or renew an existing provider network contract so that the contract as amended or renewed adds or retains an anti-steering, anti-tiering, gag, or most-favored-nation clause.

Any provision in a provider network contract that includes any of the prohibited clauses shall be void and unenforceable. The remaining provisions in the contract shall remain in effect and are enforceable.

A health benefit plan issuer that encourages an enrollee to obtain a health care service from a particular provider or that introduces or modifies a tiered network plan or assigns providers into tiers has a good faith duty to the enrollee or policyholder to engage in conduct for the benefit of the enrollee or policyholder.
