Frequently Asked Questions
What qualifies for 99285?
99285 requires high MDM with an acute problem threatening life or function, high-risk treatment, or clinical instability requiring immediate stabilization. Scribeable flags these critical elements in real time.
Can I bill both 99285 and 99291 critical care?
Yes, if critical care criteria are met separately. Bill 99285 for the ED evaluation and 99291 for additional critical care time beyond the ED visit. Scribeable helps track and document both components.
