NAICS Code 621999-19 Description (8-Digit)
Health Maintenance Organizations (HMOs) are a type of managed care organization that provides healthcare coverage to its members through a network of healthcare providers. HMOs are designed to provide cost-effective healthcare services to their members by emphasizing preventive care and early detection of health problems. HMOs typically require members to choose a primary care physician (PCP) who is responsible for coordinating all of their healthcare needs. The PCP serves as a gatekeeper, authorizing referrals to specialists and other healthcare providers as needed. HMOs also typically require members to use healthcare providers within their network in order to receive coverage, although some plans may allow for out-of-network care in certain circumstances.

History
A concise historical narrative of NAICS Code 621999-19 covering global milestones and recent developments within the United States.
- Health Maintenance Organizations (HMOs) originated in the early 20th century in the United States as a way to provide affordable healthcare to workers in specific industries. The first HMO was established in 1929 by the Ross-Loos Medical Group in Los Angeles, California. In the 1970s, the US government passed legislation that encouraged the growth of HMOs as a way to control healthcare costs. This led to a significant increase in the number of HMOs in the US, and by the 1990s, they had become the dominant form of managed care in the country. Today, HMOs are a common form of healthcare delivery in the US, and they have also been adopted in other countries around the world. Recent history of HMOs in the US has been marked by a number of changes and challenges. In the 1990s, HMOs came under criticism for limiting patients' access to care and for providing substandard care in some cases. This led to a backlash against HMOs, and many patients and employers began to seek out other forms of healthcare delivery. In response, HMOs began to change their business models, offering more flexible plans and expanding their networks of providers. Today, HMOs continue to be an important part of the US healthcare system, and they are expected to play a key role in the ongoing efforts to reform the system and improve access to care.
