A health maintenance organization, unless licensed as an insurer, shall not use in its name, contracts, or literature any words descriptive of an insurance, casualty, or surety business or deceptively similar to the name or description of any insurance or surety corporation doing business in this state. No health maintenance organization or any person on its behalf shall advertise or merchandise its services in a manner to misrepresent its services or capacity for service, nor shall it engage in misleading, deceptive or unfair practices with respect to advertising or merchandising.
