Healthcare payments is treated as a rules-based system. In practice, it doesn't behave like one. The same code, the same patient, and the same context can produce completely different outcomes depending on who's processing the claim and when. Anomaly builds payer behavior intelligence for health systems, learning from hundreds of millions of real claim outcomes across payers and regions to surface the patterns driving denials, underpayments, and delays. We don't try to explain what payers say they'll do. We show provider organizations what they actually do.
