About
Availity is the largest real-time health information network in the United States, facilitating electronic data interchange between providers and payers across the full revenue cycle. Headquartered in Jacksonville, Florida, Availity was founded in 2001 as a joint venture of major health plans and has since evolved into an independent, payer-neutral network used by more than two million providers and hundreds of health plans and payers. The platform processes billions of transactions annually covering eligibility verification, claim submission, remittance, prior authorization, and clinical document exchange.\n\nAvaility's network model creates substantial value by centralizing connectivity that would otherwise require each provider to maintain separate interfaces with dozens of payers. Providers access Availity through its free web portal or through API integrations embedded in EHR and practice management systems, while payers connect to reach the entire provider community through a single channel. This two-sided network effect has made Availity deeply embedded in the US healthcare payment infrastructure, with a level of reach that competitors find difficult to replicate.\n\nIn recent years Availity has expanded beyond basic clearinghouse functions to offer analytics, payer-specific workflow tools, and an app marketplace where third-party health IT vendors can distribute solutions to the Availity provider network. Its Availity Essentials platform provides a unified access point for administrative tasks across multiple payers, and the company has invested in AI-powered tools for denial prevention and eligibility management to increase the value it delivers to both providers and payer partners.

About
UnitedHealth Group is a Minnetonka, Minnesota-based healthcare and insurance conglomerate — publicly traded on the New York Stock Exchange (NYSE: UNH) as the largest healthcare company in the United States by revenue — reporting $400.3 billion in 2024 revenues and operating through two complementary platforms: UnitedHealthcare (health insurance serving 50+ million people) and Optum (health services including OptumHealth care delivery, OptumRx pharmacy benefit management, and OptumInsight technology and analytics). Employing approximately 400,000 people globally across 500+ locations, UnitedHealth Group has been transformed by a turbulent 2024-2025 period: the Change Healthcare ransomware cyberattack (February 2024) disrupted healthcare payments for 190 million Americans; UnitedHealthcare CEO Brian Thompson was murdered in December 2024 in New York City; and CEO Andrew Witty resigned for personal reasons in May 2025, with founder-era CEO Stephen Hemsley returning to lead the company and the 2025 earnings outlook suspended amid higher-than-expected medical costs.
