We’re actively working to monitor the new Coronavirus disease—COVID-19—and its impacts to make sure we provide our members the care they need when they need it while supporting our providers.

Coverage for members

From February 4, 2020 through December, 31, 2020 THC will cover 100% of the cost (waiving deductibles, coinsurance and co-pays) of the following COVID-related services when medically necessary:

  • COVID-19 screening and antibody testing (see additional details below).
  • Other services related to diagnostic testing and the administration of the test, such as office visits, blood draws or specimen handling.
  • Virtual Care

Prior Authorization Updates

THC is not waiving any authorization requirements at this time.  THC will work with our physicians and hospitals to provide required authorizations in a timely manner.

Use CR or CS modifier for claims related to diagnosing COVID-19

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.

If you have claims that resulted in the administration of a COVID-19 test, you should rebill claims using a CR or CS modifier 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 December 31, 2020 , 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 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
  • 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.

Visit codes billable by physicians

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.

  • Telephone Visits – Commercial ONLY
    • 99441
    • 99442
    • 99443
  • Evaluation & Management Codes – Commercial and Medicaid
    • GT modifier is required for Medicaid
    • Commercial can bill with modifiers GT or 95

Billing for COVID-19 lab tests

The Centers for Medicare and Medicaid Services (CMS) released the below codes for COVID-19 lab tests that can be used starting April1, 2020 for dates of services starting Feb. 4, 2020.For more information, see the CMS FAQ at https://www.cms.gov/files/document/cms-2020-01-r.pdf.

Code Type Base fee Note
U0001 $29.74
U0002 $42.48
U0003 $82.80
U0004 $82.80
87635 $42.48
86328 Anti-body testing $37.45 See the AMA’s website for more information.  Codes must be billed with SC Modifier to indicate medical necessity.
86769 Anti-body testing $34.88


For commercial rates, your contractual rate will be applied to the base fee.

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.”

Antibody 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.  Providers must use the SC modifier to indicate if the test was medically necessary.  Testing is covered ONLY when medically necessary.  See the following table of appropriate diagnosis codes for coverage.

The antibody testing codes are 86328 and 86769.

If a COVID-19 lab test is billed with the following diagnosis codes, the SC modifier MUST be used.  The below diagnosis codes require the SC modifier and would pay.  Audits for medical necessity may occur.

Z20 – Z20.9X Exposure to unspecified communicable disease
R05 Cough
R06.02 Shortness of breath
