Why use this calculator?
The “Split Rule” creates a compliance minefield.
Conflicting Math
CPT starts billing after the minimum time. Medicare requires the maximum time. Using the wrong math leads to denials.
The “Phantom Time” Trap
If you work 14 minutes extra, you bill $0. If you work 15, you bill a unit. Our visualizer shows exactly when you cross that threshold.
Documentation Burden
Don’t waste clinical time doing math. Our tool generates a standardized compliance statement ready for your EMR.
