FreeB is a medical billing engine. It is a collection of formats, as
well as an engine capable of connecting with any Practice Management
System that implements the FreeB API (XML-RPC). It supports
HIPAA-compliant X12 837p electronic billing and HCFA paper formats.
MirrorMed is a friendly fork of ClearHealth. It
uses the same codebase with slower releases,
further testing, and additional forms, reports,
and other small improvements. As with ClearHealth,
MirrorMed also borrows from FreeMed and OpenEMR.
