Bunkerhill Health

Agentic AI platform for health systems. Carebricks lets clinical and operational teams build, deploy, and govern their own AI agents across clinical, operational, and administrative workflows rather than buying a point solution per use case. Agents in production include coronary calcium detection on routine chest CT, nephrology triage, lung nodule follow up, referral prioritization, prior authorization packet assembly, and registry automation.

The company develops its own FDA cleared imaging algorithms that run inside the platform, including algorithms for coronary artery calcium and aortic valve calcium on contrast enhanced non gated chest CT, mitral annular calcification, and bone mineral density. CMS established a national billing code and OPPS payment for algorithmic CAC and AVC analysis on chest CT effective April 1, 2026. In production at Cleveland Clinic, the University of Texas Medical Branch, Intermountain Health, and Mayo Clinic. Founded by Nishith Khandwala, previously a researcher at Stanford's Center for Artificial Intelligence in Medicine and Imaging.

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

The product is AI infrastructure: a platform whose entire function is building, deploying, and governing AI agents, plus the company's own FDA cleared imaging algorithms that run inside it. Remove the AI and nothing remains.

CC on Autonomy and Oversight ModelAutonomy is claimed and oversight is asserted without a mechanism. Human in the loop appears as a phrase rather than a described control.
Vendor Published

Autonomy is claimed and oversight is asserted without a mechanism. Bunkerhill sells outcomes ('Name the outcome. Bunkerhill delivers.'), and its UTMB case study reports 20+ live agents with '100% of agentic workflows fully automated', including agents that flagged patients with incidental coronary calcium and initiated cardiology referrals.

UTMB's AI officer describes AI as a partner, not a replacement for human judgment, but no review step, escalation threshold or limit on what an agent may do is described. An agent authoring platform puts oversight design on the customer, and nothing published says what the platform enforces or which agent actions require clinician sign off.

BB on Model and Technology TransparencyThe approach or the suppliers are named without the version and update discipline behind them. Naming a supplier is the entry to this band both here and on Model Supply Chain Disclosure, which ask different questions of the same disclosure: who receives the data, and what produces the output.
Regulatory Filing

Two levels of disclosure inside one product. Bunkerhill's cleared imaging algorithms (coronary and aortic valve calcium, mitral annular calcification, bone mineral density, abdominal aortic diameter) have 510(k) summaries describing intended use, study design and performance. The agents and chat that make up Carebricks are described by what they do, reading imaging, reports and the full record and taking actions, with no model, version or evaluation published.

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 architecture is described and no model provider is named. Bunkerhill's agents read imaging archives, report archives and the full record and act across a health system; its own imaging algorithms are cleared devices, but the language model behind the agents and chat, the host and any subprocessor are not named, and no subprocessor list appears outside the script rendered trust center.

BB on Clinical and Operational EvidenceNamed deployments with dated outcome figures and enough method to test them, or published research short of independent validation.
Vendor Published

Named deployments with outcome figures, short of published cohort results. Bunkerhill's case studies report UTMB Health running 20+ agents across 7+ clinical domains, 80 percent faster lung nodule triage there, and 11.7 percent of routine chest CT patients found with unaddressed coronary calcium; Endeavor Health identifying 5.5 percent of routine chest CT patients for cardiac follow up; WVU improving early coronary disease detection by 7 percent; and HCA West Florida detecting coronary calcium in 58 percent of chest CT scans. The cleared algorithms have 510(k) performance summaries; the agent outcomes have no stated method or baseline.

CC on AI Safety and PHI StewardshipGeneral assurances of privacy and security that do not answer the questions artificial intelligence raises: what is retained, what reaches a model, and what happens to it there.
Vendor Published

General assurances that do not answer the questions AI raises. Bunkerhill states HIPAA compliance, SOC 2 Type II and ISO 27001, and links a trust center that may hold its policies. Its agents read imaging archives, report archives and the full longitudinal record across a health system. Nothing on the product pages states retention periods, deidentification, or whether customer data trains the agents or algorithms. Safety engineering is not published.

Regulatory and Compliance
CC on HIPAA and BAA PostureA status is stated but not supported: compliance is claimed, or business associate status stated, without the underlying document, including where the only privacy notice published covers the website rather than the service that handles patients. The mirror case grades here as well: a substantive privacy document that reaches the service, with no statement of business associate status anywhere and no scope position taken. One of the two elements the band above asks for is present, which is a grade below it and not a grade at the floor.
Vendor Published

Compliance is claimed without the document behind it. The home page states Bunkerhill is fully compliant with HIPAA privacy and security standards, alongside SOC 2 Type II and ISO 27001, and links a trust center. No business associate statement or agreement appears on the company's own pages, though the trust center may hold one.

BB on Security Certifications and Trust CenterA recognized certification is named in the vendor own material without the artifact, or with a scope or renewal question the buyer has to raise. A recognized certification here is an audit of how the vendor operates security, such as SOC 2, HITRUST or ISO/IEC 27001. A certification has a scope and a clock, and both are part of this grade. A certification the vendor attaches to its data center, hosting facility or cloud provider, rather than presenting as its own, is the host's and does not count here.
Vendor Published

Recognized certifications are named with their type, and the artifacts sit in a trust center. The home page states SOC 2 Type II, ISO/IEC 27001:2022 certification and HIPAA compliance and links a trust center on a compliance automation platform. The trust center may hold the ISO certificate scope and the SOC 2 report period; nothing outside it states them.

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 product the record leads with has no device position, while the company's own imaging algorithms are cleared. Carebricks, Bunkerhill's agent platform, runs agents for referral triage, lung nodule follow up, heart failure follow up and prior authorization with no FDA clearance and without the cleared label; a UTMB case study says it automatically initiated cardiology referrals from calcium findings.

Bunkerhill's algorithms hold 510(k) clearances in the public database, including Contrast CAC (K260166) and AVC (K243229), and the home page attaches the cleared label only to its bone mineral density measurement, correctly. CMS set a national billing code for algorithmic CAC and AVC analysis on chest CT from April 2026.

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

Governance is asserted rather than documented. Bunkerhill has described governance, monitoring and safety capabilities built into every deployment; its current home page and case studies do not repeat that, and the trust center may hold an AI policy. No framework, bias evaluation or subgroup results are published. For a platform that fully automates workflows across clinical domains, nothing published describes a review of each agent before it goes live or who signs it off.

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.
Regulatory Filing

Mechanisms exist for part of the product. The cleared imaging algorithms carry 510(k) summaries with performance and study design, plus the complaint and reporting duties of a cleared device, which gives a buyer something to hold those measurements to. The agents that act on them, initiating referrals, drafting documentation and working prior authorizations, carry no published accuracy figure, audit trail description, warranty or remediation commitment. One product carries two evidence regimes, and nothing published says which agent actions are logged or what Bunkerhill commits to when an agent acts wrongly.

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

Integration is central and no system is named. Bunkerhill's agents read clinical report and imaging archives and the EHR, and act by generating documentation, notifying care teams, initiating referrals and patient outreach, as the UTMB case study describes. No EHR, standard, listing or write back specification is named.

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

A hosted service with nothing committed about location. Bunkerhill runs Carebricks as a platform connected to a health system's imaging and report archives and EHR; no hosting provider, region, tenancy model or residency commitment appears on the home page or case studies, though the trust center may hold them.

Commercial
CC on Commercial TransparencyNo price is published and the posture is discoverable: a buyer can establish how the product is sold and what drives the cost before contacting the vendor. Most of the index sits here.
Vendor Published

No public pricing. Sold through enterprise agreements with health systems; no rate card published. The CMS billing code for CAC and AVC analysis creates a reimbursement path for certain algorithm use, which is a distinct economic question from platform licensing cost.

BB on Setting and Specialty CoverageCoverage is named with validation behind part of it.
Vendor Published

Coverage is broad by design, spanning cardiology, nephrology, pulmonary nodule follow up, oncology prior authorization, and registry operations across clinical, operational, and administrative functions. Clearly described, though breadth is a property of the platform model rather than a validated scope.

Apr 15, 2026Regulatory / FDA

CMS established a national billing code and associated payment under the Hospital Outpatient Prospective Payment System for algorithmic analysis of coronary artery calcium and aortic valve calcium on chest CT, effective April 1, 2026. The company separately received FDA clearance for Bunkerhill Contrast CAC and Bunkerhill Contrast AVC, which it states are the first AI algorithms cleared to detect and quantify coronary artery calcium and aortic valve calcium on contrast enhanced, routine non gated chest CT, extending prior clearances that covered non contrast chest CT.

Enterprise platform agreements with health systems — — Vendor Published

Enterprise platform agreements with health systems; no rate card published. Separately, CMS established a national billing code and OPPS payment for algorithmic coronary artery calcium and aortic valve calcium analysis on chest CT effective April 1, 2026, which creates a reimbursement pathway for certain algorithm use. That is distinct from the cost of licensing the platform and buyers should model the two separately.
