Typically, employer-sponsored plans can include a range of plan options. From health maintenance organizations (HMOs) and preferred provider organizations (PPOs) to plans that provide additional coverage such as dental insurance, life insurance, short-term disability insurance, and long-term disability insurance, employer-sponsored health plans can be comprehensive to meet the insurance needs of employees.
-also referred to as the Allowed Amount, Approved Charge or Maximum Allowable. See also, Usual, Customary and Reasonable Charge. This is the dollar amount typically considered payment-in-full by an insurance company and an associated network of healthcare providers. The Allowable Charge is typically a discounted rate rather than the actual charge. It may be helpful to consider an example: You have just visited your doctor for an earache. The total charge for the visit comes to $100. If the doctor is a member of your health insurance company's network of providers, he or she may be required to accept $80 as payment in full for the visit - this is the Allowable Charge. Your health insurance company will pay all or a portion of the remaining $80, minus any co-payment or deductible that you may owe. The remaining $20 is considered provider write-off. You cannot be billed for this provider write-off. If, however, the doctor you visit is not a network provider then you may be held responsible for everything that your health insurance company will not pay, up to the full charge of $100.
In the United States, Medicare is a federal social insurance program that provides health insurance to people over the age of 65, individuals who become totally and permanently disabled, end stage renal disease (ESRD) patients, and people with ALS. Recent research has found that the health trends of previously uninsured adults, especially those with chronic health problems, improves once they enter the Medicare program. Traditional Medicare requires considerable cost-sharing, but ninety percent of Medicare enrollees have some kind of supplemental insurance—either employer-sponsored or retiree coverage, Medicaid, or a private Medigap plan—that covers some or all of their cost-sharing. With supplemental insurance, Medicare ensures that its enrollees have predictable, affordable health care costs regardless of unforeseen illness or injury.
In addition to medical expense insurance, "health insurance" may also refer to insurance covering disability or long-term nursing or custodial care needs. Different health insurance provides different levels of financial protection and the scope of coverage can vary widely, with more than 40% of insured individuals reporting that their plans do not adequately meet their needs as of 2007.
