We held another session of Blue Cross NC COVID-19 Virtual Rounds on Jan. 11, 2021. See below for updates from our most recent webinar:

Coding guidance for clinical visits to determine if COVID-19 testing is necessary

Please note: Based on feedback from providers after the Jan. 11 Virtual Rounds, we have adjusted our coding guidance for commercial claims for clinical visits to determine if COVID-19 testing is necessary. 

  • For dates of service on or after Feb. 1, 2021, you have three options to indicate waiving cost share for commercial claims. It is at the discretion of the provider to choose which is appropriate.  

    • -CS modifier: Can be used to indicate diagnostic imaging, labs and physician encounters (both face-to-face and telehealth) to determine if COVID-19 testing is needed for a patient who has a confirmed or suspected exposure to COVID-19.

    • Z20.822: Contact with and (suspected) exposure to COVID-19 

      • Likely will capture the majority of encounters 

      • Place as the primary diagnosis on the claim line when contact/exposure is the reason for the encounter and the patient is asymptomatic 

    • Z11.52: Encounter for screening for COVID-19 

      • Can be used as the primary diagnosis on the claim line when screening is the reason for the encounter and the patient is asymptomatic 

  • Reminders: 

    • Medicare Advantage plans offered or administered by Blue Cross NC, including Experience Health, should continue to follow CMS guidelines for use of the -CS modifier. 

    • Providers should use the number on the back of a patient’s ID card to verify benefits for other Blues plans as not all are waiving cost share in the same way that Blue Cross NC is. 

    • For additional guidance, please visit our Details and Coding Guidance page.
