Medical Coding for COVID-19 Novel Coronavirus

Optum360® is committed to ensuring that you have the information you need to effectively and efficiently address COVID-19 from a medical coding, billing and reimbursement perspective. We have compiled information from the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS), American Medical Association (AMA), and the Centers for Medicare and Medicaid Services (CMS), so you can easily access the most up-to-date medical code detail and effective dates in one convenient place.


COVID-19 ICD-10-CM Coding

There is one new ICD-10-CM code for COVID-19, effective April 1, 2020:

U07.1 COVID-19

The CDC posted the official ICD-10-CM Coding and Reporting Guidelines for COVID-19 for April 1, 2020-September 30, 2020.

The Centers for Disease Control and Prevention (CDC) issued a health alert on Thursday, May 14, 2020, outlining the case definition for multisystem inflammatory syndrome in children (MIS-C), which has been recently associated with COVID-19: COVID-19 Related Condition: Multisystem Inflammatory Syndrome in Children (MIS-C) (113 KB) 

Summary of COVID-19 code changes as of 7.6.20 (166 KB).

COVID-19 CPT® Coding

One new CPT® code was created for reporting new coronavirus 2 (SARS-CoV-2) COVID-19 testing, effective March 13, 2020.

87635    Infectious agent detection by nucleic acid (DNA or RNA); severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (New Coronavirus disease [COVID-19]), amplified probe technique)

Two new CPT® codes were created, one revised, for reporting COVID-19 antibody testing, effective April 10, 2020. 

86318     Immunoassay for infectious agent antibody(ies), qualitative or semiquantitative, single step method (eg, reagent strip);

#86328   Immunoassay for infectious agent antibody(ies), qualitative or semiquantitative, single step method (eg, reagent strip); severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19])

Code #86328 is a resequenced code that follows code 86318.

86769     Antibody; severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19])

A new Proprietary Laboratory Analysis CPT® code was created for reporting coronavirus 2 (SARS-CoV-2) COVID-19 testing, effective May 20, 2020.

0202U     Infectious disease (bacterial or viral respiratory tract infection), pathogen-specific nucleic acid (DNA or RNA), 22 targets including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), qualitative RT-PCR, nasopharyngeal swab, each pathogen reported as detected or not detected

A new CPT code and two PLA CPT codes were created for reporting coronavirus 2 (SARS-CoV-2) COVID-19 testing, effective June 25, 2020.

87426     Infectious agent antigen detection by immunoassay technique, (eg, enzyme immunoassay [EIA], enzyme-linked immunosorbent assay [ELISA], immunochemiluminometric assay [IMCA]) qualitative or semiquantitative, multiple-step method; severe acute respiratory syndrome coronavirus (eg, SARS-CoV, SARS-CoV-2 [COVID-19])
0223U     Infectious disease (bacterial or viral respiratory tract infection), pathogen-specific nucleic acid (DNA or RNA), 22 targets including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), qualitative RT-PCR, nasopharyngeal swab, each pathogen reported as detected or not detected
0224U     Antibody, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19]), includes titer(s), when performed

NOTE: A HCPCS code and CPT® code should not be reported together. Providers should contact third-party payer(s) for reporting either a CPT® or a HCPCS code, as well as for retroactive billing and reimbursement guidelines.

Summary of COVID-19 code changes as of 7.6.20 (166 KB).


COVID-19 HCPCS Coding

Two new HCPCS Level II codes were created for new coronavirus testing, effective April 1, 2020, for dates of service starting February 4, 2020.

U0001   CDC 2019 Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel For tests developed only by the CDC (reporting allows CDC testing laboratories to test new patients and track new cases).

U0002   2019-nCoV Coronavirus, SARS-CoV-2/2019-nCoV (COVID-19), any technique, multiple types or subtypes (includes all targets), non-CDC

For laboratories performing non-CDC testing.

Two new HCPCS Level II codes were created for coronavirus testing using high throughput technologies, effective April 14, 2020 (reportable for services provided on March 18, 2020 and forward).

U0003   Infectious agent detection by nucleic acid (DNA or RNA); Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19]), amplified probe technique, making use of high throughput technologies as described by CMS-2020-01-R.

U0004   2019-nCoV Coronavirus, SARS-CoV-2/2019-nCoV (COVID-19), any technique, multiple types or subtypes (includes all targets), non-CDC, making use of high throughput technologies as described by CMS-2020-01-R

Two new HCPCS Level II codes were created for specimen collection, effective March 1, 2020.

G2023   Specimen collection for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19]), any specimen source

G2024   Specimen collection for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19]) from an individual in a SNF or by a laboratory on behalf of a HHA, any specimen source

A new HCPCS Level II code was created for coronavirus specimen collection for hospital outpatient clinics effective March 1, 2020:

C9803   Hospital outpatient clinic visit specimen collection for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19]), any specimen source

Modifier CS was revised and may be appended to COVID-19 related testing services provided on or after March 18, 2020 to identify the cost-sharing waiver is applied and the Medicare patient should not be charged co-insurance or deductible.

CS       Cost-sharing for specified COVID-19 testing-related services that result in an order for or administration of a COVID-19 test

COVID-19 DRG Coding

The CMS has released an update to the ICD-10 MS-DRG grouper software package to accommodate the new diagnosis code, U07.1 for COVID-19, effective with discharges on and after April 1, 2020.

The ICD-10 MS-DRG Grouper assigns each case into an MS-DRG based on the reported diagnosis and procedure codes and demographic information (age, sex, and discharge status).

The assignment of new ICD-10-CM diagnosis code U07.1 COVID-19 is as follows:

Diagnosis Code Description CC MDC MS-DRG
U07.1 COVID-19 MCC
04
15
25
