Cohere Health vs ZeOmega (2026)
Cohere Health and ZeOmega provide health plans with authorization and clinical administration software. Cohere combines review automation with optional delegated clinical services. ZeOmega places its Smart UM modules within the broader Jiva platform for care management, benefits, quality and member engagement. Cohere accepts requests through portals, APIs and providers' Epic workflows. Models approve requests meeting criteria and send the rest to clinicians; the company states that AI does not deny care. Plans can use their own reviewers or Cohere's specialty teams. Its Humana case describes a long running deployment and shorter time to service, with company reported results. The thresholds behind automatic approval, and how errors are recovered, go undescribed. ZeOmega's modules cover fax extraction, FHIR authorization exchange, approval likelihood, policy conversion and assisted clinical review. Policy conversion is clinician guided, and reviewers receive highlighted evidence and suggested responses. Configurable logic routes exceptions to staff, with an explicit policy against AI denials. Established Jiva customer accounts describe care coordination but do not validate each newer Smart UM component. Cohere fits plans choosing between operating authorization internally and delegating specialty review. ZeOmega fits organizations adding selected authorization functions to a wider enterprise care platform. Both retain clinical responsibility for exceptions; Cohere emphasizes the review delivery model, while ZeOmega offers modular intake, policy and decision support within configurable health plan workflows.
- The plan wants optional delegated specialty review.
- Authorization software needs access to the vendor's nurses and physicians.
- Provider Epic workflows need a named request submission path.
- A platform, embedded APIs and managed review must be available choices.
- Authorization needs to sit within broader care and benefits operations.
- The plan wants selected intake or review modules independently.
- Medical policies need clinician guided conversion into decision trees.
- Fax extraction and FHIR exchange are specific implementation priorities.

Questions buyers ask
How are Cohere Health and ZeOmega priced and sold?
Cohere sells to health plans in three shapes: a platform the plan's own clinicians run, delegated utilization management run by Cohere's clinicians for named specialties, and APIs embedded into plan systems; payment integrity is sold in house or as a managed audit service. The only economics published are returns, up to 18x for prior authorization and 9x for payment integrity, which say what a plan gets back and not what it pays.
With ZeOmega, the commercial structure is clear; a calculable price is not. Subscription amounts, per-member or usage units, module charges, implementation fees, and minimum commitments only emerge in a sales discussion. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified October 15, 2026. No vendor pays for placement.
How do Cohere Health and ZeOmega handle patient data?
Cohere's AI principles state the AI never uses explicit patient identifiers, such as names or locations, for care recommendations, and its AI Hub describes a minimum necessary approach that reads only the clinical information a decision needs.
For ZeOmega, the enterprise service sets out no patient-data retention, permissions for model training or reuse, or deidentification rules. Detailed hallucination acceptance thresholds and a model safety incident process are also unclear. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified October 15, 2026. No vendor pays for placement.
Which settings and specialties do Cohere Health and ZeOmega cover?
Cohere names delegated programs in musculoskeletal, cardiovascular, gastrointestinal, sleep, diagnostic imaging and sepsis care, and products across utilization management, payment integrity, appeals, care management, claims operations and quality.
In ZeOmega's case, the broader product spans care management, quality, risk adjustment, social needs, and authorization workflows rather than one clinical specialty. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified October 15, 2026. No vendor pays for placement.
What evidence is published for Cohere Health and ZeOmega?
For Cohere Health, the Humana case study (August 2026) reports a partnership since January 2021 across all 50 states and 5.1 million Medicare Advantage and commercial members, with 95 percent provider digital adoption, an 89 percent auto approval rate, time to service five days shorter, 54 percent fewer nurse review hours and 94 percent of providers satisfied.
With ZeOmega, the accessible case describes integration, care management, and compliance workflows, but gives no dated quantitative evaluation, comparator, or measurement method.
