Find Out How Much Your Out-of-Network Claims Are Being Underpaid
MultiPlan, Zelis, and Data iSight cut out-of-network payments to a fraction of your billed charges, and most practices never contest them. Tell us about your OON volume and we’ll show you, claim by claim, how far those reductions fall below a fair benchmark and what is still recoverable. No cost, no obligation.
✓ Allowed amount vs. FAIR Health benchmark on a sample of your claims
✓ Which repricer and payer are cutting you the most
✓ Which claims are still inside the appeal window (some repricers allow only 14 days)
✓ Estimated recoverable dollars across your OON book
We sign a BAA before we see any claim data.

“We were losing $8,400 per month to preventable denials. Happy Billing found patterns in our claims data we didn’t even know existed. First 90 days: $43,000 recovered”

Dr. Sarah L, MD
“I was skeptical about outsourcing, but the transparency changed everything. I can see every claim, every denial, every dollar in real-time. It’s like having a world-class billing team without the headcount”

Dr. Jennifer W, MD
How the underpayment analysis works
1. Tell us about your out-of-network claims
The form takes under a minute: practice, contact details, and how you’d like us to follow up. No claim data goes through the form.
2. Send a sample of remits securely
After a short call we sign a BAA and send a secure upload link. A few weeks of 835s or EOBs for OON claims is enough to see the pattern.
3. Get a claim-by-claim underpayment report
For each sampled claim: billed charge, allowed amount, the repricer that touched it, the benchmark it should have paid near, and whether it can still be appealed, disputed through IDR, or escalated to your state regulator.
Who this is for
Physical therapy, chiropractic, sports medicine, orthopedic, and behavioral health practices that bill out of network, especially in New Jersey and New York, where repricing disputes can be escalated to DOBI or DFS.
