Operating platform for certified independent dispute resolution entities (IDREs) under the No Surprises Act, combining case management with payments, escrow, and reconciliation.
TypeScriptNext.jsPrismaMySQLAWSTrigger.dev
Problem
IDREs arbitrate thousands of payment disputes between healthcare providers and health plans under strict federal deadlines. Case work, fee collection, escrow, refunds, and disbursements often live in separate tools, which slows resolution and makes every dollar harder to trace.
Approach
Develop a full-stack Next.js and TypeScript platform that covers intake, eligibility, arbitration, and closure together with fee collection, ACH payment files, escrow balances, CMS fee reconciliation, and reporting. Background jobs on Trigger.dev and AWS handle deadlines, notifications, and syncing with CMS dispute data.
Impact
Brings case operations and money movement into one auditable system, reducing manual reconciliation and helping entities keep up with dispute volume and regulatory change without stitching tools together.
