Answer: If the chart documentation supports an E/M service (99281-99285) in addition to CPR, you may bill one with modifier -25 appended. The exception: You can't bill CPR when the physician performs it during minutes you're counting toward critical care time. Remember that when you report critical care, the time involved must be separate from time spent performing other separately billable procedures. As long as the chart supports a separately identifiable ED E/M service, you should code one.
