Alaffia Health vs Cohere Health (2026)
Two payer side platforms that both design oversight carefully, pointed at different workflows. Alaffia is the payment integrity specialist: it digitises and cross references claims against the full record and policy, saves a reported $120 million, and is built for defensibility with anti black box logic, traceable citations, clinician sign off, and a SOC 2 Type II and HITRUST cert set. Cohere is the utilization management leader: prior authorization at network scale with the strongest evidence in this lane, and the clearest safety architecture in the category, stated as auto approve up to 85 percent, never auto deny, with clinicians deciding the rest. Both earn an A on autonomy, from different principles. The tiebreakers are scope and evidence against governance: Cohere has the fuller outcome record including provider measured satisfaction but a historical data bias gap graded C, while Alaffia's evidence is vendor reported at B. If your failure mode is payment integrity on high cost facility claims with maximally defensible determinations, start with Alaffia. If your failure mode is prior authorization at scale with a stated safety asymmetry, start with Cohere.
- Payment integrity is the specialism: OCR digitises unstructured bills and records, agents cross reference each claim against the full patient record and policy criteria, with a reported $120 million saved and over 20 percent average savings on high cost facility claims, graded A on AI centrality.
- Defensible by design: anti black box, clinical rationale and traceable citations on every recommendation, licensed clinician sign off, graded A on autonomy, plus a named certification set of SOC 2 Type II, HIPAA, and HITRUST, graded B on security.
- Precisely bounded to health plan claims operations and honest that it is specialised for the payer rather than a general tool, with roughly 30 day go live.
- Prior authorization at network scale with the strongest evidence in this lane: a reported 15 million plus submissions carried through the APIs, 47 million payer provider interactions annually, and provider satisfaction measured from the counterparty at 94 percent with an NPS of 67, graded A on clinical evidence.
- The safety asymmetry stated explicitly: the AI auto approves up to 85 percent in real time and does not auto deny, with the remainder reviewed by a clinician, the correct architecture for prior authorization and graded A on autonomy.
- Reaches the whole network, not just digital members: submissions accepted by phone, fax, and web as well as EHR integration, graded A on interoperability, with named plan relationships including Humana and Geisinger.

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Alaffia Health its top capability grade on AI Centrality, Autonomy and Oversight Model and Setting and Specialty Coverage. Set against Cohere Health, Alaffia Health grades higher on AI Governance and Bias Disclosure and Commercial Transparency. Its thinnest published disclosure sits on AI Liability and Recourse. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Alaffia Health or Cohere Health?
On the axes where the AI Health Index separates them, Alaffia Health grades higher on AI Governance and Bias Disclosure and Commercial Transparency, and Cohere Health grades higher on several axes, including Clinical and Operational Evidence, Security Certifications and Trust Center and FDA and Regulatory Status. Cohere Health leads on the greater share of scored axes, but the split means the decision turns on which constraint is binding rather than on an overall winner.
Where do Alaffia Health and Cohere Health differ most?
The widest separation the AI Health Index records between Alaffia Health and Cohere Health is on FDA and Regulatory Status, where Alaffia Health grades C and Cohere Health grades A. That axis sits in the Regulatory and Compliance group, so it should carry the most weight for a buyer whose binding constraint is where regulatory exposure sits and who carries it.
Where do Alaffia Health and Cohere Health grade the same?
The AI Health Index grades Alaffia Health and Cohere Health the same on several axes, including AI Centrality, Autonomy and Oversight Model and Model and Technology Transparency. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.
What have Alaffia Health and Cohere Health not disclosed?
At the last review, at least one of Alaffia Health and Cohere Health published thin or absent detail on AI Liability and Recourse. The AI Health Index treats an absent disclosure as a gap in the public record rather than a failure of the product, so these are the axes to get in writing during diligence instead of inferring from the grade.

Both are payer side, both grade A on AI centrality, and both grade A on autonomy but earn it differently: Alaffia through anti black box design and clinician sign off, Cohere through the auto approve, never auto deny asymmetry that is its entire safety argument. Cohere carries the stronger evidence, graded A, notably provider satisfaction measured from the counterparty rather than the buyer, which is meaningful evidence a payer tool is not simply obstructing care.
Cohere's gap is governance, graded C, since models trained on historical authorization data can reinforce existing denial patterns and no bias evaluation was located. Alaffia's evidence is graded B, vendor reported without independent audit, and payment integrity savings are notoriously hard to attribute. Both are partially assessed, roughly six axes each.
Neither publishes pricing, and both use return on investment framing that implies savings linked economics, so a buyer should establish whether compensation scales with denials or with cycle time, since those create opposite incentives at the clinician review checkpoint.
