Fight Denials
Your insurer denied your claim hoping you’d give up. Kupu analyzes the denial, finds the billing errors hiding inside it, generates your appeal with the right regulatory citations, and manages the fight through resolution.
Catch Billing Errors
Seven detection algorithms scan every bill for duplicates, unbundled procedures, overcharges against Medicare benchmarks, and more. These errors often cause denials — and they become the evidence that strengthens your appeal.
Track Everything
Kupu tracks your deductible, out-of-pocket max, and charges across every provider. It flags when your insurer’s numbers don’t match yours and catches billing errors before they become denials.
Four steps to clarity
From upload to understanding to action.
Scan Your Documents
Denial letters, medical bills, EOBs — take a photo or upload a PDF. Kupu’s OCR extracts every line item, charge, code, and denial reason automatically.
Kupu Analyzes
Seven detection algorithms check for billing errors, unbundled procedures, overcharges, and coding mistakes. For denials, Kupu classifies the denial type and matches it against federal regulations.
Fight and Win
Kupu generates appeal and dispute letters with the right regulatory citations, manages deadlines, and guides you through escalation. For bills without denials, it flags errors and builds your case.
Track and Protect
Every document flows into your account — tracking your deductible, out-of-pocket max, and spending across providers. Kupu catches problems early so you’re never blindsided.
