Banjo Health vs Cohere Health (2026)
Two payer side prior authorization platforms, splitting on benefit type and on breadth. Banjo is pharmacy benefit weighted, reading prescriber notes directly and producing an inspectable structured recommendation with the evidence attached rather than a score, backed by HITRUST at the risk based tier. Cohere is the broader clinical intelligence platform, covering utilization management, payment integrity, appeals, care management and policy management for health plans, which suits an organization that wants one consistent model of medical necessity across all of them. The question neither answers, and the one that should decide this, is what proportion of AI recommended denials are overturned on appeal. A platform that is fast and wrong costs more than the staff it replaced, and in this workflow the cost lands on a patient waiting for treatment rather than on the plan.
- It is weighted toward pharmacy benefit rather than medical, which is a genuinely different determination workflow, and it reads prescriber notes directly rather than working from a submitted form alone.
- Its central output is an inspectable structure rather than an opaque score, and every recommendation carries detailed evidence, which is the correct design when the output can result in a denial.
- HITRUST at the risk based two year tier, which incorporates the privacy requirements and is the more demanding assessment rather than the lighter entry level one.
- The platform reaches beyond authorization into payment integrity, appeals, care management and policy management, so one vendor covers the utilization management estate rather than one decision point.
- The clinical intelligence framing is broader and the customer base larger, which matters when a plan wants a single model of medical necessity applied consistently across functions.
- Accreditation matters here in a way it does not elsewhere, and the stronger accredited posture transfers benefit to the plan rather than leaving it exposed.

Each vendor in one paragraph
Written to be quoted whole. Each paragraph opens the AI Health Index profile of the vendor: what the product is, who buys it and what it does.
Prior authorization, appeals and grievances platform for health plans and pharmacy benefit managers, across medical and pharmacy benefits. BanjoPA uses CARE (Computer Assisted Review Engine) to extract information from faxed and digital requests, create the case and match it against the plan's clinical criteria, recommending approve, deny or request more information with evidence and an explanation; a human reviewer confirms or adjusts every recommendation.

Cohere Health sells a clinical intelligence platform, Cohere Unify, to health plans. Its modules cover utilization management, payment integrity, appeals, care management, claims operations and HEDIS quality work. Prior authorization requests arrive through Cohere's portal, its APIs, Availity, NaviNet or a provider's Epic workflow.

Questions buyers ask
How do Banjo Health and Cohere Health work with the EHR?
Banjo says it works with EHRs, eligibility verification tools, claims management systems, ePA vendors and API ready portals, ingests faxed and digital requests, and runs appeals through the same ePA vendor as the original request.
Cohere's platform page also names Availity, NaviNet and Rhyme as routes in, and lists the CMS-0057-F prior authorization APIs (coverage requirements, documentation templates and prior authorization support) built to the HL7 Da Vinci guides. Plans can embed the service in their own systems through Cohere's APIs, and providers can also use its portal. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified August 4, 2026. No vendor pays for placement.
How are Banjo Health and Cohere Health priced and sold?
In Banjo Health's case, enterprise agreements with health plans and pharmacy benefit managers. CMS prior authorization rules are the stated adoption driver, so contracts may be negotiated under a compliance deadline, and the pricing page does not say whether pricing reflects the deadline driven implementation or steady state operation.
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. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified August 4, 2026. No vendor pays for placement.
How do Banjo Health and Cohere Health handle patient data?
Banjo's October 2025 post states its AI is proprietary, designed from the ground up, and not an open source model, giving it control over every layer of the technology stack, so case data is not described as reaching an outside model provider. It also says the AI is constantly learning and adapting, which implies customer determinations improve the models, and nothing says whether that learning stays within one plan's boundary.
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. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified August 4, 2026. No vendor pays for placement.
What evidence is published for Banjo Health and Cohere Health?
Banjo reports 50 percent faster intake to decision, 70 percent less time drafting and updating decision trees and a 33 percent reduction in appeals, with no baseline, period or customer.
Cohere's August 2026 case study reports a partnership since January 2021 covering 5.1 million Medicare Advantage and commercial members in all 50 states. It reports 95 percent of providers submitting digitally, 89 percent of requests approved automatically, time to service five days shorter and 54 percent fewer nurse review hours, with 94 percent of providers satisfied.

Prior authorization is the workflow where an AI output most directly results in care being delayed or denied, and neither vendor publishes a bias evaluation or subgroup performance analysis. Washington's rule states that a carrier is not exempt from prior authorization compliance because it used a third party vendor and requires the program to meet a national accreditation standard, so vendor accreditation transfers benefit and its absence transfers burden; establish which accreditations each vendor holds for the specific program you are buying. Neither publishes pricing. Both should be asked what proportion of AI recommended denials are overturned on appeal, which is the number that reveals whether the model is calibrated or merely fast.
