Patient-side medical billing advocate
The only advocate on the patient’s side of the bill.
Paxer audits the medical bills and EOBs you actually receive, finds the errors, and helps you get your own money back. Every other tool in medical billing works for the hospital. Paxer works for you.
Of bills contain errors
Industry estimates put error rates on complex, itemized hospital bills in this range.
Saved by Paxer users
In duplicate charges, denials, and cost-share errors caught and recovered.
Free for individuals
Paxer is free for patients — we never take a cut of what you recover.
What Paxer finds
Four kinds of error, hiding in plain sight.
Duplicate & unbundled charges
The same service billed twice, or one procedure split into separately billed parts to inflate the total.
Cost-share miscalculations
Your deductible, coinsurance, and out-of-pocket max recomputed from your real plan, then checked against what you were charged.
Balance billing & surprise bills
Out-of-network and emergency charges billed above your in-network cost-share, a likely No Surprises Act violation.
Upcoding & overruns
Higher-intensity codes than the service described, and charges above the regional benchmark for the same code.
How it works
Three steps, and you stay in control.
Add your bill
Upload a medical bill or EOB, or enter the charges by hand. Paxer reads the document and pulls out every line item.
See the findings
The audit engine checks each charge against your plan and regional benchmarks, and flags errors with the evidence and the math behind each one.
Send & recover
Paxer drafts the dispute letter. You review it, send it to your provider or insurer, and Paxer tracks the deadline until the money comes back.
For businesses & developers
The same audit engine, as an API.
Patient-billing platforms, HSA/FSA admins, and clinics can check a bill for errors with one API call. Free for individuals; usage-based for businesses.
