Your billing team already asks Claude. Now it can answer.
The denial questions your team types into Claude every day, answered with real payer data instead of a guess. Plus the methodology behind it. All public, all separate from the platform.
What does Upstream open source?
The parts a billing team or a builder can use on their own: a Claude MCP server, Claude Code skills for denial and prior-auth work, open reference implementations of the denial-detection methodology on public data, and a curated list of payer-risk resources. The production engine, the network, and patient data stay private.
Open-source tools
We open the methodology. We keep the engine and your data private.
The open repositories teach the techniques on public CMS data. The production system runs them at scale across the operator network, on live data, behind real controls. No patient information is ever part of what we publish.
Building near this work?
If you are building close to specialty billing, start with the open tools, then talk to us about the platform and the data network behind them.
