COVID-19 Billing and Coding in 2022: What You Need to Know
This article presents a brief guide for COVID-19 billing and coding procedures. It includes all the latest E/M updates for 2022.
We hope that this guide will prove useful to your medical practice in maintaining effective billing practices during the era of COVID-19.
1. The Importance of Modifier CS in COVID-19 Billing
According to the latest COVID-19 billing guidelines, modifier CS is used in two billing and coding contexts:
- Virtual or face-to-face visit for suspected or likely COVID-19 exposure
- Diagnostic tests relating to COVID-19 but not including a COVID-19 test
Let’s look at each case in turn.
Suspected or Likely COVID-19 Exposure
The usual E/M codes used to bill virtual/face-to-face visits for suspected COVID-19 exposure are:
- ICD-10 codes Z03.818, Z20.822, and Z20.828
- Modifier CS
- In the case of virtual care, append modifiers GQ, GT, or 95
Cost-share will be waived through April 20th, 2021.
It is important to understand that cost-share will be waived for COVID-19-related services only when the provider bills the correct ICD-10 code as well as modifier CS.
Note that modifier CR or condition code DR may also be billed instead of modifier CS. Moreover, services not related to COVID-19 will have standard customer cost-share.
Diagnostic Tests Relating to COVID-19
For tests relating to COVID-19, other than a COVID-19 test, the usual codes are:
- ICD-10 code Z03.818, Z20.822, or Z20.828
- Modifier CS
In general, these codes are used for laboratory tests done when COVID-19 may be suspected. These tests must be reasonable procedures to help rule out the possibility of COVID-19.
Be aware that, if a COVID-19-related test is included in a laboratory panel code, only the code for the panel test will be reimbursed.
However, if the test is not part of a laboratory panel, but instead is part of a series of pathogen tests performed, the relevant unbundling edits may apply.
Note that cost-share is waived until April 20th, 2021 only when providers bill the appropriate ICD-10 code and modifier CS, and only when the tests are reasonable attempts to rule out the possibility of COVID-19.
Modifier CR and condition code DR may also be used for billing instead of modifier CS.

2. New Diagnosis Codes Added For COVID-19 Billing
Effective January 1st, 2021, the CDC and NCHS (National Center for Health Statistics) have implemented six new diagnosis codes. These are included in the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM).
These 2021 ICD-10-CM codes should be used for patient encounters as well as discharges occurring from October 1st, 2020 through September 30th, 2021.
These six new diagnosis codes are:
- J12.82 Pneumonia due to coronavirus disease 2019
- M35.81 Multisystem inflammatory syndrome
- M35.89 Other specified systemic involvement of connective tissue
- Z11.52 Encounter for screening for COVID-19
- Z20.822 Contact with and (suspected) exposure to COVID-19
- Z86.16 Personal history of COVID-19
These new diagnosis codes were originally proposed at the September 2020 ICD-10 Coordination and Maintenance Committee (C&M).
According to the ICD-10-CM Tabular List of Diseases and Injuries, when reporting code J12.82 or M35.81, coders are required to first report code U07.1 for COVID-19, if it is applicable.
3. Extension of Public Health Emergency
The current Public Health Emergency (PHE) is in place through April 20th, 2021. It was extended in January 2021, almost a year to the day after the PHE was initially declared in January of 2020.
Due to this extension, multiple flexibilities and waivers remain in effect. This includes, for example, Medicare telehealth coverage of speech-language pathology services. It also included relaxed HIPAA requirements (be aware that HIPAA by and large remains in effect).
Moreover, many commercial insurers have extended their enhanced telehealth access guidelines for the duration of the PHE.
Insurers are continually implementing additional accommodations pertaining to virtual care and telehealth through the PHE period. If you are curious about a particular insurer’s policy, make sure to review their policies on virtual care services.
The key takeaway from the extension of the PHE is that non-COVID-19 virtual visits are to be billed with the usual face-to-face E/M codes. These are:
- Append with GQ, GT, or 95 modifier
- POS for face-to-face service normally billed
In general, insurers such as Cigna will reimburse the usual face-to-face rates for services that, due to the pandemic, are delivered remotely. This is an exception allowed only during the PHE.
