How does a PPO plan work?
As a member of a PPO (Preferred Provider Organization) plan, you'll be encouraged to use the insurance company's network of preferred doctors and hospitals. These healthcare providers have been contracted to provide services to the health insurance plan's members at a discounted rate. You typically won't be required to pick a primary care physician but will be able to see doctors and specialists within the network at your own discretion. You will probably have an annual deductible to pay before the insurance company starts covering your medical bills. You may also have a co-payment for certain services or be required to cover a certain percentage of the total charges for your medical bills. With a PPO plan, services rendered by an out-of-network physician are typically covered at a lower percentage than services rendered by a network physician.
How does an HMO plan work?
Though there are many variations, HMO (Health Maintenance Organizations) plans typically enable members to have lower out-of-pocket healthcare expenses but also offer less flexibility in the choice of physicians or hospital than other health insurance plans. As a member of an HMO, you'll be required to choose a primary care physician (PCP). Your PCP will take care of most of your healthcare needs. Before you can see a specialist, you'll need to obtain a referral from your PCP. With an HMO you'll likely have coverage for a broader range of preventive healthcare services than you would through another type of plan. You may not be required to pay a deductible before coverage starts and your co-payments will likely be minimal. With an HMO plan, you typically won't have to submit any of your own claims to the insurance company. However, keep in mind that you'll likely have no coverage whatsoever for services rendered by non-network providers or for services rendered without a proper referral from your PCP.                                                                                                                                                                                                  What is the difference between in-network and out-of-network providers?
An in-network provider is one contracted with the health insurance company to provide services to plan members for specific pre-negotiated rates. An out-of-network provider is one not contracted with the health insurance plan. Typically, if you visit a physician or other provider within the network, the amount you will be responsible for paying will be less than if you go to an out-of-network provider. Though there are some exceptions, in many cases, the insurance company will either pay less or not pay anything for services you receive from out-of-network providers. As a general rule, PPO and HMO plans make use of provider networks. Indemnity plans typically do not.
