Alaffia Health vs Cohere Health (2026)
Two payer side platforms built on the same oversight rule, that automation may approve and only a clinician may deny, pointed at different work. Alaffia is built for payment integrity, with agents that read itemized bills and medical records, check each claim against the patient record, clinical criteria and policy, and route cases to reviewers with a rationale and citations, sold as software for the plan's team or as a managed clinical review service. Cohere is built for utilization management at scale, approving prior authorization requests that meet criteria in real time, 85 percent on its home page and 89 percent at Humana, and pending the rest for a clinician, with 17 health plan clients and a Humana relationship running since 2021 across all 50 states. If your failure mode is review of complex or high cost facility claims, start with Alaffia. If it is prior authorization volume across a large membership, start with Cohere.
- Payment integrity is the specialism, covering itemized bill, DRG and complex claims review before and after payment, plus prior authorization and appeals, with every recommendation carrying a clinical rationale and traceable citations.
- Licensed clinicians review every AI recommendation, clear approvals can be automated, and the company states its AI is never used to deny care.
- Plans can buy it as agents for their own team or as a managed service in which Alaffia's clinicians do the reviews, insourced, hybrid or fully outsourced, live in about 30 days.
- Scale is documented with a named customer, as Humana has used the platform since 2021 across all 50 states and 5.1 million members, reporting an 89 percent auto approval rate, 54 percent fewer nurse review hours and 94 percent of providers satisfied.
- Requests arrive through Cohere's portal, its APIs or providers' Epic workflow through Epic's Payer Platform, and plans can run it with their own clinicians or delegate specialty review to Cohere's nurses and physicians.
- HITRUST r2 certification and URAC and NCQA utilization management accreditation are stated, and its privacy policy states business associate status.

Other published head to head assessments involving these vendors or their closest peers.
Both report outcome figures without independent evaluation. Alaffia's 97 percent accuracy, 20 times throughput and $30 million regional case carry no method or named plan, and Cohere's figures come from its own case studies. Both state commitments to fair outcomes without publishing subgroup results, and Cohere's models learn from historical authorization decisions that can carry past patterns forward.
Alaffia shows SOC 2 Type 2 and HITRUST badges without a report, period or level, and publishes no business associate position. Neither publishes a price or fee basis, and fees that scale with savings would pull against an approve only automation design.
