I show a system that uses a local MedGemma model to detect billing issues in under a minute, then redacts patient identifiers before any cloud call. Only the redacted text is sent to cloud Opus 4.7, and the results can flag disputable charges like duplicates and out of network violations. I can show you a demo, and the end of the recording includes a sample disputed letter.
