Ethos acquires Definiti

Ethos has acquired Definiti , a provider of workers’ compensation medical cost containment services, expanding its capabilities in bill review, PPO and ancillary network access, rules-based cost containment technology, and pharmacy benefit management through Definiti Rx.

The deal enhances Ethos’ national bill review offering and broadens its suite of services available to carriers, TPAs, self-insured employers, and public sector clients. Definiti will continue operating under its existing leadership team, while gaining access to Ethos’ broader platform over time.

“Bill review is one of the most important levers our clients have to control medical spend, and Definiti has built a reputation for getting it right,” said Micah Smith, CEO of Ethos. “Their technology, their service ethic, and their long-tenured client relationships are exactly what we look for in a partner. Together, we’re giving carriers, TPAs and self-insured employers a deeper, more connected set of tools to manage workers’ compensation outcomes.” – Micah Smith, CEO of Ethos Risk Services .

The acquisition follows Ethos’ purchases of ForzaCare in 2025 and Claims Eval in 2024, continuing the company’s strategy of building an integrated claims services platform spanning investigations, medical management, utilization review, peer review, case management, independent medical examinations, bill review, and pharmacy services.
