Health Insurance POS To illustrate this point, this is how these plans typically work. When medical care is needed, the individual plan member essentially has up to two or three choices, depending on the particular health plan. The plan member can choose to go through his or her primary care physician, in which case services will be covered under HMO guidelines (i.e., usually a co-payment will be required). Alternatively, the plan member can access care through a PPO provider and the services will be covered under in-network PPO rules (i.e., usually a co-payment and coinsurance will be required). Lastly, if the plan member chooses to obtain services from a provider outside of the HMO and PPO networks, the services will be reimbursed according to out-of-network rules (i.e., usually a co-payment and higher coinsurance charge will be required). Because people who belong to POS plans are responsible for deciding how to access care within the various options, it is important that they understand the financial implications of these choices.Where Do People Get Health Insurance Coverage? Group InsuranceMost Americans get health insurance through their jobs or are covered because a family member has insurance at work. This is called group insurance. Group insurance is generally the least expensive kind. In many cases, the employer pays part or all of the cost.Some employers offer only one health insurance plan. Some offer a choice of plans: a fee-for-service plan, a health maintenance organization (HMO), or a preferred provider organization (PPO), for example. Employers with 25 or more workers are required by Federal law to offer employees the chance to enroll in an HMO.What happens if you or your family member leaves the job? You will lose your employer- supported group coverage. It may be possible to keep the same policy, but you will have to pay for it yourself. This will certainly cost you more than group coverage for the same, or less, protection.A Federal law makes it possible for most people to continue their group health coverage for a period of time. Called COBRA (for the Consolidated Omnibus Budget Reconciliation Act of 1985), the law requires that if you work for a business of 20 or more employees and leave your job or are laid off, you can continue to get health coverage for at least 18 months. You will be charged a higher premium than when you were working.You also will be able to get insurance under COBRA if your spouse was covered but now you are widowed or divorced. If you were covered under your parents' group plan while you were in school, you also can continue in the plan for up to 18 months under COBRA until you find a job that offers you your own health insurance.Not all employers offer health insurance. You might find this to be the case with your job, especially if you work for a small business or work part-time. If your employer does not offer health insurance, you might be able to get group insurance through membership in a labor union, professional association, club, or other organization. Many organizations offer health insurance plans to members.
