HMO stands for Health Maintenance Organization. HMO plans must go to network providers to get medical care and services. Members must select a primary care physician within the provided network and require a PCP referral before seeing a specialist. That doesn't mean they can't ever see a doctor who's outside the HMO network. But, unless it's an emergency, the member may have to pay the total cost for their medical care.
