What One Call Care Management does
One Call Care Management, headquartered in Jacksonville, Florida, is a technology-enabled care coordination platform serving the U.S. workers' compensation industry. Founded in 1985 and operating as a privately held company with 1,001-5,000 employees, One Call unifies ancillary care services — diagnostics, physical medicine, dental, durable medical equipment and prosthetics, transportation, language services, and home health — into a single platform accessed by payers, third-party administrators, self-insured employers, and provider networks. Its proprietary technology includes OneSight Analytics (provider benchmarking and network management), Gold Standard Review (peer-to-peer clinical oversight), Age of Injury (radiology causality review), RelayRIDES (transportation coordination), and At-Risk predictive analytics; the platform serves more than one million injured workers annually across 4,100+ diagnostic provider locations and supports interpretation in 200+ languages.
The company generates revenue through transaction-based fees on coordinated ancillary services plus recurring subscription fees for analytics and network management, with multi-year enterprise contracts and quote-based pricing. Customers reach the platform via product-specific provider portals (Polaris, Diagnostics Customer Center, OneSight Harbor Health, I-Supplier DME, Relay Solutions), direct sales to payers/TPAs/employers, and physician referrals. In April 2026 One Call completed the acquisition of Data Dimensions, an EDI clearinghouse and technology services provider (formerly a Thompson Street Capital Partners portfolio company), extending the platform into electronic data interchange, Providerflow workflow automation, Digitalization-as-a-Service, and integrated payments — creating end-to-end infrastructure linking intake, clinical coordination, data exchange, and payments.
One Call completed a strategic refinancing in September 2025 led by Apollo with participation from Chatham Asset Management, Blackstone Credit, and KKR, and operates with a C-suite led by CEO Nick Mendez (appointed January 2025), supported by functional chiefs across finance, technology, operations, legal, HR, and commercial functions.
