A health care plan that provides or that is required by law to provide coverage for emergency services shall provide coverage such that payment under this coverage is not dependent upon whether the services are performed by a plan or non-plan health care provider and without regard to prior authorization. This coverage shall be at the same benefit level as if the services or treatment had been rendered by the health care plan physician licensed to practice medicine in all its branches or health care provider. Prior authorization or approval by the plan shall not be required for emergency services.
