CR Modifier for COVID-19 PHE - Revised

On February 9, the Department of Health and Human Services (HHS) announced the Public Health Emergency (PHE) for COVID-19 will end on May, 11, 2023External Website. Since the CR modifier should only be reported during a PHE when a formal waiver is in place, plan to discontinue using it and the COVID-19 narrative for claims with dates of service on or after May 12, 2023. The CR modifier may be required for a different emergency declaration, but not COVID-19.

Since the COVID-19 PHE is ending, CGS is providing the following reminders about the use of the CR modifier. The CR modifier and "COVID-19" narrative should only be appended when all the following apply:

  • Claims for dates of service March 1, 2020-May 11, 2023; and
  • The items provided fall under the scope of a blanket waiver or flexibility listed in the chart in MLN Matters SE20011External PDF.
