Use CR or CS modifier for claims related to diagnosing COVID-19; facilities add condition code DR

Provider offices, urgent care and emergency rooms should bill us using a CR or CS modifier anytime the visit resulted in a COVID-19 test being ordered. Facilities should also use condition code DR to identify when the services provided resulted in a COVID-19 test being administered. To properly identify as a COVID-related visit, a diagnosis code of Z20.828 (Contact with and (suspected) exposure to COVID-19) is expected.

If you have claims that resulted in the administration of a COVID-19 test, you should rebill claims using a CR or CS modifier or DR modifier with condition code dating back to February 4, 2020. Using this modifier will ensure your patients have a $0 cost share for any visit and services related to the diagnostic testing and administration of the test.

These codes should not be added to services billed for treatment of COVID-19.

Virtual visits billing and coverage

Effective March 1, 2020 through September 30, 2021 at a minimum, we will allow credentialed providers to bill routine practice codes with a Place of Service 02 (to include  GT modifier for Medicaid; GT or 95 modifier for Commercial).  As of July 1, 2020, we will pay according to the non-facility Medicaid rate and no longer require a COVID diagnosis to waive patient cost share.  The visit must follow the guidelines for the code billed, including time requirements.

What does this mean? Any credentialed practitioner can conduct a telemedicine visit, including wellness visits, and bill with a Place of Service 02 and the appropriate modifier, which identifies the visit as being virtual.

For example, office procedures billed with an evaluation and management (E/M) code of 99201-99215, when performed in real-time by credentialed providers through an interactive tool that can be audio-only, can have a Place of Service 02 with modifier added and receive the standard non-facility-based rate.

What’s not included? You cannot:

  • Use codes that specify in-person or describe services that can only be performed in person
  • Bill for services you’re not contracted to provide
  • Perform services outside of your scope of practice, licensure or credentialing
  • Bill behavioral health codes; Beacon Health is providing telemedicine visits without cost-sharing through their provider network.

Given the government’s notification, we’re temporarily suspending the requirement for HIPAA compliant systems and are also allowing for real-time, interactive audio-only telehealth encounters to service patients who don’t have internet access or audio-visual capabilities.   This means that if you don’t have a virtual care tool in place, you can use non-public facing tools, like FaceTime, Facebook Messenger video chat, Skype, etc. You cannot use public-facing tools like Facebook Live, TikTok or chat rooms like Slack.   See the Office for Civil Rights FAQ for more information.

THC reimburses fee-for-service for the below listed codes when billed with POS 02 on a professional claim.  Co-pays and deductibles will apply based on office visits.  Claims will be reimbursed based on the non-FAC fee at your contractual rate as of 6/1/2020.

The Michigan Department of Health and Human Services (MDHHS) advises you complete the Human Infection with 2019 Novel Coronavirus Person Under Investigation (PUI) and Case Report Form if a patient tests positive for COVID-19.

Diagnosis Codes

Starting April 1, add ICD-10 code U07.1 COVID19 when your patients have a diagnosis of COVID-19. Until April 1, you should continue to follow the CDC’s recommendation for coding.

Note that diagnosis code B34.2, Coronavirus infection, unspecified, would in generally not be appropriate for the COVID-
19, because the cases have universally been respiratory in nature, so the site would not be “unspecified.”

COVID-19 Testing

THC will cover antibody testing with no member cost share, COVID-19 testing (any type) when it is ordered by a provider and medically necessary. Testing is covered ONLY when medically necessary. Audits for medical necessity may occur

The antibody testing codes are 86328 and 86769.
