Health insurance helps to protect individuals and families against financial loss. Having health insurance also promotes access to regular health care. Most Americans with private health insurance are covered through an employer, or through the employer of a family member. A recent study by the Robert Wood Johnson Foundation found that in 2012, 59.5% of insured Americans had their insurance through an employer. When an employee is terminated, his or her employer-sponsored health insurance usually ends within 30 to 60 days. If that health insurance is family coverage, then a worker’s family members can also become uninsured. Even if the worker finds another job with health benefits, a family can experience long periods of uninsurance, as they wait to qualify for the new benefit. This same problem is also faced by families that experience a reduction in hours in the workplace, the death of a worker, or a divorce. In 1985, Congress passed legislation to provide the unemployed temporary access to their former employer’s health insurance. Under Title X of the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA; P.L. 99-272), an employer with 20 or more employees who provided health insurance benefits must provide qualified employees and their families the option of continuing their coverage under the employer’s group health insurance plan in the case of certain events. The former employee is responsible for paying the entire premium. Employers who fail to provide the continued health insurance option are subject to penalties. This report provides background on COBRA, a brief explanation of the program, its origins, issues, and how the Affordable Care Act might impact COBRA.
