Mandolin

Mandolin automates the administrative work required to start and sustain specialty drug treatment. Its agents read referrals and clinical records, investigate insurance benefits, estimate patient costs, assemble prior authorization submissions and follow claims through payer portals and calls. The San Francisco company operates as Coral Automation, doing business as Mandolin.

The product is designed for infusion centers, specialty pharmacies and health systems. It works through existing software interfaces, fax and telephone rather than depending on new API connections. Intake agents extract information from varied documents and enter it into the EHR. Medical policy workflows compare payer requirements with the patient's chart, while benefits calls produce transcripts and audit trails that staff can use when a claim is disputed.

Clinical decisions remain with clinicians under Mandolin's stated design principles. Ambiguous records and conflicting fields require review, even as routine operational steps are automated. Customer accounts describe faster document processing and reduced prescription backlogs, but the outcome examples are anonymous and lack measurement dates. Investor Greylock separately names Vivo, FlexCare, OI Infusion and TwelveStone as deployments. The service policy covers PHI, executed BAAs and possible use of deidentified data for model improvement. Commercial terms and deployment scope are arranged through sales; no rate card is available.

Capability Axes

An AI Health Index grade measures what a buyer can verify from public sources on the date shown. It is not a rating of how good the product is. A vendor can build an excellent system and grade low on an axis because it publishes nothing an outsider can check. How grades read

AI Capability
AA on AI CentralityThe artificial intelligence is the product. Remove the model and there is nothing left to sell.
Vendor Published

Mandolin's agents interpret referral documents, compare charts with payer policies, navigate portals and make phone calls to complete specialty drug administration. Learned language, vision and multimodal reasoning are central to that work, rather than an optional reporting feature. The same operational context follows a patient from intake through benefits verification, authorization and claims follow up.

Deterministic checks can handle defined fields, while ambiguous clinical documentation is prepared for expert review. Without the models, the current offer would lose the ability to interpret varied records and carry work across systems, which is the principal service being sold.

BB on Autonomy and Oversight ModelThe oversight structure is described and one part is missing, commonly the threshold at which the system stops or what happens after it is wrong.
Vendor Published

Agents can enter records, make payer calls and submit authorization requests, so their role extends beyond drafting suggestions. The current design philosophy separates deterministic work from ambiguous material and keeps treatment necessity and safety decisions with a clinician. Its examples route contradictory diagnosis information toward human review, cross check inconsistent measurements and preserve source wording behind classifications.

Call transcripts and action logs support subsequent review. The public workflow description does not specify confidence thresholds, mandatory stop conditions or an override process for each task. Broad automation language therefore coexists with a meaningful but incompletely specified human oversight structure.

CC on Model and Technology TransparencyThe architecture is described in general terms with nothing identified. Proprietary is asserted rather than explained.
Vendor Published

The technical account describes a shared operational context that combines vision, language and multimodal reasoning across structured records, clinical notes and other documents. Agents interact with EHR interfaces, payer portals and telephone systems, while defined checks can be handled through rules. This gives a functional architecture for how work is coordinated. It does not identify a foundation model provider, model family, version or update schedule.

Training data are discussed primarily through privacy rules for deidentified material, rather than through a technical description of datasets and evaluation. The current material explains behavior more fully than the underlying model stack.

CC on Model Supply Chain DisclosureThe architecture is described and no model provider is named. Naming a hosting provider alone does not lift a record out of this band. Record the host in the note, because it matters for residency and breach scope, and grade on the model layer, which is the question this axis is named for.
Vendor Published

The privacy policy contemplates third party AI developers and model development platforms, with deidentification or BAA based safeguards for shared information. It also describes categories of service providers such as hosting, analytics, support and security. Specific model providers and a named subprocessor roster are not included.

As a result, the public account does not establish which organizations process a clinical document or call transcript, nor the retention and training terms that apply at each stage. A general promise to bind PHI subcontractors is meaningful, but it does not enumerate the model processing chain for the current agents.

CC on Clinical and Operational EvidenceNamed customers, or vendor reported percentages with no method, denominator or reference standard. Scale of use is recorded here and is not treated as evidence of benefit.
Vendor Published

The homepage describes a document intake workflow falling from twenty minutes to three minutes per document, an eliminated prescription backlog and a separate infusion operation serving more than 4,500 patients monthly. These accounts identify customer types and operational baselines, but not customer names, measurement dates or a controlled comparison. Greylock names Vivo, FlexCare, OI Infusion and TwelveStone as deployments in its June 2025 investment announcement.

Those names substantiate use, while the scale figures describe reach rather than benefit. The available accounts do not connect a named customer to a dated, reproducible performance study or independently measured patient outcome.

BB on AI Safety and PHI StewardshipCategorical commitments are published, such as no training on customer data, without the retention schedule behind them.
Vendor Published

Customer records and AI generated insights can contain PHI. The policy permits deidentified or aggregated information to train, validate and improve models, and requires appropriate safeguards or explicit BAA permission for outside model development. Retention follows customer instructions, contractual requirements and the purpose of processing, followed by deletion or anonymization when information is no longer needed. Encryption, access controls and incident response are also stated.

There is no numerical retention schedule for prompts, transcripts, outputs or backups, and no detailed deidentification method. The policy therefore supplies categorical commitments without a complete operational account of the AI data lifecycle.

Regulatory and Compliance
BB on HIPAA and BAA PostureBusiness associate status is stated and supported by a substantive privacy document, with the agreement or its scope not fully published. For a vendor outside the United States, an equivalent regime documented to this depth grades here. A vendor whose product does not process protected health information grades here too when it says so plainly and explains the scope, with a service privacy document behind it: stating a position a buyer can rely on is the posture this axis grades, and the band above is closed to it because there is no agreement to publish.
Vendor Published

The service privacy policy identifies Coral Automation, doing business as Mandolin, as a business associate when providing services to healthcare organizations. It states that PHI handling is governed by an executed BAA and that subcontractors handling PHI must also sign one. The policy covers the healthcare platform itself, including records and AI outputs, rather than website tracking alone. A complete public BAA and a product or subscription level availability schedule are not included.

Patients are directed to their healthcare organization for record rights, with Mandolin assisting under the agreement. This establishes a substantive service posture while leaving contract specifics private.

DD on Security Certifications and Trust CenterControls are asserted with nothing independent behind them, or nothing is published. Read the note before concluding anything: this is the grade most often corrected on a second pass, because assurance material frequently sits on a parent domain or inside an old announcement rather than on the product pages.
Vendor Published

The homepage displays a HIPAA compliance badge, and the privacy policy describes encryption, access controls, vulnerability management, staff training and incident response. These are security practices and compliance assertions, rather than evidence of an independent security assessment. No named SOC 2 report, ISO certificate or comparable third party artifact is attached to the current public offer. Regular security assessments are mentioned without an assessor, scope or report.

The badge therefore does not establish outside certification. The product's access to EHR accounts, payer portals and patient records makes the assessment boundary especially relevant to understanding any future assurance claim.

CC on FDA and Regulatory StatusNo device claim is made and the product is scoped accordingly. Most administrative and operational products sit here and are not penalized for it, because this axis grades the appropriateness of the positioning rather than possession of a clearance.
Vendor Published

The described purpose is administrative support for access to specialty therapies: collecting records, checking benefits, assembling authorization submissions and following claims. Medical policy review involves clinical information, but the current design explicitly reserves decisions about whether treatment is necessary and safe for a clinician. No FDA authorization is attached to this administrative product.

Examples involving laboratory values, diagnosis codes and drug histories describe the information that staff must verify, rather than an independently cleared diagnostic function. The boundary is particularly relevant where data entry affects later treatment decisions, since administrative positioning does not make an incorrect record harmless.

CC on AI Governance and Bias DisclosureResponsible artificial intelligence is committed to in policy language with no evaluation behind it. Most of the index sits here.
Vendor Published

The privacy policy commits to mitigating bias through continuing evaluation and improvement. Product design articles add more specific review principles: preserve clinical context, flag conflicting information and keep consequential treatment decisions with clinicians. These are useful commitments, but they do not include subgroup evaluation methods or results for patient populations, languages, drug categories or payer workflows. No independent AI governance assessment is identified.

The available detail also leaves the process for approving model changes, tracking regression and resolving a recurring bias issue unspecified. Action logs can support investigation of an incident without establishing that systematic disparities have been measured.

CC on AI Liability and RecourseMechanisms exist that let someone challenge an output, such as audit trails, source traceability or review before commit, with nothing standing behind the output and no route for the harmed party.
Vendor Published

Benefits verification combines payer call execution with transcripts and audit trails. That record can help staff reconstruct what was asked, what the payer answered and how an authorization relates to a later denial. The current denial article explicitly acknowledges that transcripts and authorization do not guarantee recovery, and that exceptional cases still need human coordination. These features support traceability and correction, not a contractual transfer of reimbursement risk.

There is no stated output warranty, indemnity for a mistaken verification or defined financial remedy for an incorrect submission. The financial consequences of relying on agent output remain governed by private commercial terms.

Integration and Deployment
CC on EHR and Interoperability DepthIntegration is claimed through standards or a middleware layer with no system named and nothing to verify.
Vendor Published

Mandolin reads referral forms, laboratory reports and clinical notes and enters the extracted information into an EHR. Benefits and claims work can use payer portals, fax and telephone, so the product is designed to operate through existing interfaces without requiring an API integration. That is a concrete interaction pattern, but no named EHR connector, supported version matrix or verified production marketplace listing accompanies it.

The available detail does not establish the limits of record writeback, reconciliation or failure recovery. Interface automation can connect a workflow operationally while still leaving the reliability of each specific system combination unresolved.

CC on Deployment Model and Data ResidencyA single hosted option with location implied rather than committed.
Vendor Published

The privacy policy places the service's servers and central database in the United States and describes possible transfers there for users outside the country. The offer is a hosted healthcare platform; separate on premises or customer cloud options are not identified. A cloud provider, tenant isolation design and region specific processing commitments are also unspecified.

The US location is useful context, but it does not map every path taken by model inputs, generated outputs, support access and backups. Encryption and contractual safeguards address protection during processing without supplying a complete residency and deployment specification.

Commercial
DD on Commercial TransparencyNothing a buyer can establish before a sales conversation. A published pricing claim contradicted by evidence also grades here.
Vendor Published

Sales contact is required to establish the commercial terms. The current offer spans intake, benefits investigation, patient cost estimation, prior authorization and claim follow up, but there are no public subscription figures, transaction rates or package boundaries. It is unclear whether charges depend on locations, patients, workflows, completed tasks or another unit.

Customer stories describe staffing changes and faster processing, which indicate the intended economic benefit without revealing fees. Funding amounts also concern the company rather than the cost of its software. Implementation charges, minimum commitments and the treatment of failed or exceptional tasks remain unspecified.

BB on Setting and Specialty CoverageCoverage is named with validation behind part of it.
Third Party Estimated

The focus is specialty therapy operations at infusion centers, specialty pharmacies and health systems. Greylock's June 2025 account names Vivo, FlexCare, OI Infusion and TwelveStone among live users, providing identifiable examples of the intended setting. Workflows span referral intake, benefits, medical policy review and reimbursement rather than a single disease.

Current clinical operations articles discuss the documentation needs of multiple sclerosis and thyroid eye disease therapies as illustrations. These examples explain the complexity of the work, but they are not specialty specific validation studies. Performance across drug categories, payer policies and different delivery settings is not established uniformly.
