## Overview

The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic consisting of 50 states and a federal capital district, Washington, D.C. The 48 contiguous states border Canada to the north and Mexico to the south, with the semi-exclave of Alaska in the northwest and the archipelago of Hawaii in the Pacific Ocean. The United States also asserts sovereignty over five major island territories and various uninhabited islands in Oceania and the Caribbean. It is a megadiverse country, with the world's third-largest land area and third-largest population, exceeding 341 million.

## Healthcare system

Healthcare in the United States is largely provided by private sector healthcare facilities, and paid for by a combination of public programs, county indigent health care programs, private insurance, and out-of-pocket payments. The U.S. is the only developed country without a system of universal healthcare, with around 92% of the population covered under some kind of health insurance for some, or all of the year. The United States spends more on healthcare than any other country, both in absolute terms and as a percentage of GDP; however, this expenditure does not necessarily translate into better overall health outcomes compared to other developed nations. In 2022, the United States spent approximately 17.8% of its Gross Domestic Product (GDP) on healthcare, significantly higher than the average of 11.5% among other high-income countries. Coverage varies across the population with certain groups. This includes the elderly, disabled, and low-income individuals receiving more comprehensive care through government programs such as Medicaid and Medicare.

## Practical info

Healthcare in the United States is largely provided by private-sector facilities and paid for through a combination of public programmes, private insurance and out-of-pocket payments; there is no system of universal healthcare, and more comprehensive cover through government programmes such as Medicare and Medicaid applies to groups including the elderly, disabled and low-income individuals. Costs and payment arrangements should therefore be confirmed with the treating facility, and with an insurer where cover applies, before travel. The UK Foreign Office advises travellers to research their destination and obtain appropriate travel insurance covering their itinerary, planned activities and expenses in an emergency. Care is delivered in English, with Spanish also used in medical settings. The currency is the US dollar, and the unified emergency number for police, ambulance and fire is 911. Visa and entry rules are not documented in this registry's current sources, so travellers should check official US government guidance for their nationality before booking treatment.
