The AI platform for Claim Integrity
One engine reads clinical and financial data, understands payer rules, and applies judgment to the claim. Upstream it prevents the bad claim. Downstream it audits the claim at scale.
Two flagship applications. RxAI for the pharmacy supply chain. Audit.ai for payers and audit organizations.
"The claim is decided long before billing ever sees it."
The same intelligence that prevents a bad claim is the intelligence that recognizes one. Upstream it catches the error. Downstream it audits the claim. The direction changes. The judgment does not.
Purpose-built AI applications. Powered by Grelin
Each application targets a specific pre-bill revenue risk — all powered by the same intelligence engine.
