# How Signal Works

Catching documentation gaps before they become denied claims

Without Signal
Patient flagged for CGM resupply
Staff manually tracks documentation across spreadsheets and faxes
Claim filed to payer
Denial: documentation incomplete
SWO missing · Qualifying visit overdue · PA not confirmed
Appeal filed — 6 to 8 week delay
Write-off or supply shipped at a loss
vs

Gaps flagged on prioritized worklist — before any claim is filed
