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.

01

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.

02

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.

03

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.
