CMS-1450 in practice

Knowing what CMS-1450 means is only useful if it changes what your team does. In a modern revenue cycle, that means catching issues related to claims & Adjudication earlier, documenting and coding them correctly, and using technology to flag exceptions automatically rather than discovering them after a claim is denied.
