Persistent lack of insurance among many working Americans continued to create pressure for a comprehensive national health insurance system. In the early 1970s, there was fierce debate between two alternative models for universal coverage. Senator Ted Kennedy proposed a universal single-payer system, while President Nixon countered with his own proposal based on mandates and incentives for employers to provide coverage while expanding publicly run coverage for low-wage workers and the unemployed. Compromise was never reached, and Nixon's resignation and a series of economic problems later in the decade diverted Congress's attention away from health reform.
In 2009, the main representative body of British Medical physicians, the British Medical Association, adopted a policy statement expressing concerns about developments in the health insurance market in the UK. In its Annual Representative Meeting which had been agreed earlier by the Consultants Policy Group (i.e. Senior physicians) stating that the BMA was "extremely concerned that the policies of some private healthcare insurance companies are preventing or restricting patients exercising choice about (i) the consultants who treat them; (ii) the hospital at which they are treated; (iii) making top up payments to cover any gap between the funding provided by their insurance company and the cost of their chosen private treatment." It went in to "call on the BMA to publicise these concerns so that patients are fully informed when making choices about private healthcare insurance." The practice of insurance companies deciding which consultant a patient may see as opposed to GPs or patients is referred to as Open Referral. The NHS offers patients a choice of hospitals and consultants and does not charge for its services.
Since 1974, New Zealand has had a system of universal no-fault health insurance for personal injuries through the Accident Compensation Corporation (ACC). The ACC scheme covers most of the costs of related to treatment of injuries acquired in New Zealand (including overseas visitors) regardless of how the injury occurred, and also covers lost income (at 80 percent of the employee's pre-injury income) and costs related to long-term rehabilitation, such as home and vehicle modifications for those seriously injured. Funding from the scheme comes from a combination of levies on employers' payroll (for work injuries), levies on an employee's taxable income (for non-work injuries to salary earners), levies on vehicle licensing fees and petrol (for motor vehicle accidents), and funds from the general taxation pool (for non-work injuries to children, senior citizens, unemployed people, overseas visitors, etc.)
A Health care sharing ministry is an organization that facilitates sharing of health care costs between individual members who have common ethical or religious beliefs. Though a health care sharing ministry is not an insurance company, members are exempted from the individual responsibility requirements of the Patient Protection and Affordable Care Act.
Over time, the operations of many Blue Cross and Blue Shield operations have become more similar to those of commercial health insurance companies. However, some Blue Cross and Blue Shield plans continue to serve as insurers of last resort. Similarly, the benefits offered by Blues plans, commercial insurers, and HMOs are converging in many respects because of market pressures. One example is the convergence of preferred provider organization (PPO) plans offered by Blues and commercial insurers and the point of service plans offered by HMOs. Historically, commercial insurers, Blue Cross and Blue Shield plans, and HMOs might be subject to different regulatory oversight in a state (e.g., the Department of Insurance for insurance companies, versus the Department of Health for HMOs). Today, it is common for commercial insurance companies to have HMOs as subsidiaries, and for HMOs to have insurers as subsidiaries (the state license for an HMO is typically different from that for an insurance company). At one time the distinctions between traditional indemnity insurance, HMOs and PPOs were very clear; today, it can be difficult to distinguish between the products offered by the various types of organization operating in the market.
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.
