Shorthand for the “Health Insurance Marketplace,” a shopping and enrollment service for medical insurance created by the Affordable Care Act in 2010.
In most states, the federal government runs the Marketplace (sometimes known as the “exchange”). On the web, it’s found at HealthCare.gov. Some states run their own Marketplaces at different websites.
You can shop for and enroll in affordable medical insurance online, by phone, or with in-person help from a trained assister or an agent or broker.
There’s a separate Marketplace — called the Small Business Health Options Program (SHOP) Marketplace — where small businesses with fewer than 50 employees can shop for and buy medical insurance for their employees.
