A health benefit plan provider may require that, if coverage is provided through a managed care plan, the benefits mandated under this chapter are covered benefits only if the prosthetic devices or orthotic devices are provided by a vendor or a provider, and related services are rendered by a provider, that contracts with or is designated by the health benefit plan provider. If the health benefit plan provider provides in-network and out-of-network services, the coverage for prosthetic devices or orthotic devices provided through out-of-network services must be comparable to that provided through in-network services.
