Inside the Workflow


Intelligence before the claim is submitted
Traditional revenue cycle management focuses on fixing problems after claims are denied. Grelin focuses on preventing those problems before the claim is ever sent.
01 · AnalyzeWhat we analyze
Eligibility, documentation, coding, payer rules, and charges validated before submission.
02 · DetectReal-time risk surfacing
Grelin flags risks early, helping teams fix issues before claims enter billing.
03 · ResolveUpstream resolution
Issues are identified and resolved early before claims are denied and correction costs increase.
AI built for healthcare revenue cycle risk
Grelin applies machine learning and automation to revenue cycle data in real time, identifying claim risks across eligibility verification, clinical documentation, medical coding, charge capture, and payer policy before submission.

Eligibility Validation
Confirms payer coverage, benefit eligibility, authorization requirements, and billing policies before services are billed, helping reduce denials, delays, claim errors, reimbursement risks, and unnecessary rework across the revenue cycle.
Claim Audit and Integrity Review.
Audit.ai, Grelin's payment integrity application, runs submitted healthcare claims through layered AI audit checks that surface coding errors, coverage conflicts, and fraud risk before payment.

Frequently Asked Questions
Find answers about the Grelin platform, our products, and how we help healthcare organizations improve claim accuracy.
What is Grelin Health?
Grelin Health is a healthcare AI company that builds the platform for Claim Integrity. The platform validates that claims are correct, complete, and defensible before submission and audits them before payment. It serves payers, providers, pharmacy distribution, and government programs.
What products does Grelin offer?
Four applications on one platform. RxAI validates pharmacy claims across the distribution supply chain. Audit.ai audits claims for payers before payment. RCM.ai validates provider claims before submission. Chart.ai turns clinical documentation into defensible claims, with specialty modules for wound care, pain management, behavioral health, and durable medical equipment.
Who is Grelin for?
Health plans and payers that audit claims. Provider organizations that submit them. Pharmacy distributors that move claims across networks. Technology companies that embed validation into their own platforms. Each group runs a different application on the same underlying platform.
Does Grelin replace billing teams?
No. The platform takes over the manual review work machines do better, like checking a claim against payer policy line by line. Billing teams keep the judgment work: exceptions, appeals, and payer relationships. The goal is fewer claims that need rework, not fewer people.
How does Grelin fit with the systems we already run?
Grelin sits alongside existing systems rather than replacing them. It reads from the electronic health record, practice management, or claims system, runs its checks, and returns results into the existing workflow. Deployment can be direct or embedded inside a partner platform.
How is Grelin different from a claim scrubber?
A scrubber checks format and basic edits at submission. Grelin validates substance: whether documentation supports the codes, whether the payer's specific policy is met, whether eligibility holds. A scrubber catches a missing field. Claim Integrity catches a claim that is clean on format and wrong on content.
Is Grelin a software company or a services company?
Software. The applications are licensed annually and run inside the customer's or partner's workflow. Grelin does not take over billing operations or staff them. The product is validation logic, applied earlier in the claim lifecycle than existing tools reach.
How does Grelin use AI?
Grelin uses AI to read clinical documentation, apply payer-specific policy, and check claims at volume. Every automated verdict carries its reasoning, and exceptions route to human review. AI is the mechanism that makes early validation possible at scale. The product is the validation.
