Health Insurance HMO There may be a small co-payment for each office visit, such as $5 for a doctor's visit or $25 for hospital emergency room treatment. Your total medical costs will likely be lower and more predictable in an HMO than with fee-for-service insurance.Because HMOs receive a fixed fee for your covered medical care, it is in their interest to make sure you get basic health care for problems before they become serious. HMOs typically provide preventive care, such as office visits, immunizations, well-baby checkups, mammograms, and physicals. The range of services covered vary in HMOs, so it is important to compare available plans. Some services, such as outpatient mental health care, often are provided only on a limited basis.In some HMOs, doctors are salaried and they all have offices in an HMO building at one or more locations in your community as part of a prepaid group practice. In others, independent groups of doctors contract with the HMO to take care of patients. These are called individual practice associations (IPAs) and they are made up of private physicians in private offices who agree to care for HMO members. You select a doctor from a list of participating physicians that make up the IPA network. If you are thinking of switching into an IPA-type of HMO, ask your doctor if he or she participates in the plan.In almost all HMOs, you either are assigned or you choose one doctor to serve as your primary care doctor. This doctor monitors your health and provides most of your medical care, referring you to specialists and other health care professionals as needed. You usually cannot see a specialist without a referral from your primary care doctor who is expected to manage the care you receive. This is one way that HMOs can limit your choice.Before choosing an HMO, it is a good idea to talk to people you know who are enrolled in it. Ask them how they like the services and care given.Questions to Ask About an HMOAre there many doctors to choose from? Do you select from a list of contract physicians or from the available staff of a group practice? Which doctors are accepting new patients? How hard is it to change doctors if you decide you want someone else? How are referrals to specialists handled?Is it easy to get appointments? How far in advance must routine visits be scheduled? What arrangements does the HMO have for handling emergency care?Does the HMO offer the services I want? What preventive services are provided? Are there limits on medical tests, surgery, mental health care, home care, or other support offered? What if you need a special service not provided by the HMO?What is the service area of the HMO? Where are the facilities located in your community that serve HMO members? How convenient to your home and workplace are the doctors, hospitals, and emergency care centers that make up the HMO network? What happens if you or a family member are out of town and need medical treatment?What will the HMO plan cost? What is the yearly total for monthly fees? In addition, are there copayments for office visits, emergency care, prescribed drugs, or other services? How much?Many people like HMOs because they do not require claim forms for office visits or hospital stays. Instead, members present a card, like a credit card, at the doctor's office or hospital. However, in an HMO you may have to wait longer for an appointment than you would with a fee-for-service plan.
