Precision Healthcare AI
About Grelin Health | AI Claim Integrity Company
Grelin Health builds AI software that validates healthcare claims before submission and audits claims before payment.
AI Intelligence Platform for Claim Integrity.
We bring clarity to complexity. Our AI intelligence platform automates audits, reduces risk, and ensures accuracy across every healthcare workflow.
Our Mission
Understand the whole patient. Hand it to every system.
Every system in healthcare sees a slice of one patient. None of them reads across the full history.
Providers
The condition that matters sits in a letter nobody opened before the visit.
Payers
Care that is not clearly written down is paid and taken back later, and every take back has to hold up on appeal.
Patients
A diagnosis documented years ago never reaches the clinician in front of them today.
Section 3 · Why Grelin Exists
The revenue cycle worked backwards for decades.
Claims went out. Denials came back. Teams investigated, corrected, and resubmitted. The work was real. It just happened too late. Grelin moves the work upstream. Every claim, every specialty, validated before it reaches the payer.
Our Core Principles
What We Believe
Intelligence is upstream work
The right time to read the whole history is before the provider signs, not after the claim comes back.
The stack you have is the stack you keep.
Healthcare doesn't need another disruptive platform that requires “ripping and replacing.” We believe AI should be an invisible layer that integrates seamlessly with existing EMRs and Billing systems, enhancing what works and fixing what doesn't.
Specialty knowledge is the moat.
Generic AI models cannot audit complex healthcare claims. We believe true Claim Integrity requires deep, specialty-specific medical intelligence that mirrors the expertise of the highest-performing human auditors.
One engine. Four products.
What the platform does
The Grelin engine ingests clinical history, maps it to clinical and payer rules written as Playbooks and runs the same reading, reasoning and evidence trail under every product.
Four Products
Chart.ai is the Healthcare Intelligence layer and the product the company is built around. RCM.ai, RxAI and Audit.ai apply the same engine to the claim for revenue cycle teams, pharmacy and payers. Specialty Playbooks for wound care, pain management, behavioral health and DME run inside them.
- Chart.ai Precision Healthcare Intelligence
- RCM.ai Claim & Revenue Cycle Validation
- RxAI Pharmacy Distribution Intelligence
- Audit.ai Payer Claim Integrity
Built by physicians and technologists who have operated inside the revenue cycle.
How We Work
Build from the inside out. We don't build technology for clinicians; we build it from their perspective. Every feature starts with a workflow reality.
Plain language always. Complexity is the enemy of integrity. We translate arcane medical coding and AI outputs into clear, actionable English.
No “Black Box” AI. Auditing requires accountability. Every AI-driven decision must be explainable, citeable, and transparent.
Precision over Scale. We would rather be perfectly accurate in one specialty than moderately helpful in ten. Quality is our true metric.
Speed with Certainty. Integrity shouldn't slow down care. Our platform is built for real-time validation without clinical friction.
