27 New ICD-10 Codes for COVID-19-Related Conditions, Approved Monoclonal Antibodies, & More Take Effect January 1, 2021

CMS will implement a total of 27 new codes for COVID-19 related conditions, circumstances, and treatment – including approved monoclonal antibodies – on January 1, 2021. This includes six ICD-10-CM diagnosis codes and 21 ICD-10-PCS procedure codes. This off-cycle release of codes follows the early release of the COVID-19 code in April 2020, as well as the 12 new ICD-10-PCS codes for introduction or infusion of therapeutics that CMS implemented on August 1, 2020.

Also, do you want to learn how to apply the new 2022 ICD-10 COVID-19 codes? Sign up for our COVID-19 ICD-10 Coding Learning Path and find out how to code Coronavirus infections, symptoms, screening, post-COVID-19 condition, treatments, ICD-10 code for COVID antibody infusion and vaccines. The webinar also provides an update to the FY2022 Official Coding Guidelines for COVID-19.

New ICD-10-CM Codes for COVID-19

The six new diagnosis codes were first introduced at the September 8, 2020, Coordination and Maintenance Committee meeting. In addition, all of the codes have been approved for implementation on January 1, 2021 (CDC, 2020). A formal addendum with the tabular entries and index modifications will be published on the NCHS website soon (CDC, 2020).

approved monoclonal antibodies

The six new codes include a specific code for pneumonia due to COVID-19; two codes in the diseases of the musculoskeletal system and connective tissue; one for multisystem inflammatory syndrome (MIS), along with a code for other specified systemic involvement of connective tissue; and three Z codes for screening, exposure and personal history of COVID-19. Furthermore, impending guideline updates will incorporate these new codes.

COVID-19 Diagnosis Codes

The 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

New ICD-10-PCS Codes for COVID-19

Furthermore, the procedure codes effective on January 1, 2021, are all found in the New Technology XW0 code table and represent substances used in the treatment of COVID-19. CMS also lists the codes on the CMS ICD-10-PCS website as of December 1, 2020 (CMS, 2020). Additionally, they include 10 codes for approved monoclonal antibodies, six codes for vaccine administration, and five codes for other specified substances.

In addition, the reporting of these codes will not affect the MS-DRG assignment. ICD-10 designates these as non-OR procedures, and CMS has not assigned any MDC or MS-DRGs. See the CMS website under Latest News ICD-10-MS-DRSs 38.1 for an announcement of both the diagnosis and procedure codes and links to other resources (CMS, 2020).

ICD-10 Code for COVID Antibody Infusion

Furthermore, the 10 codes for approved monoclonal antibodies represent four specific types: Bamlanivimab, Etesevimab, Leronlimab, and REGN-COV2. Note that Leronlimab is injected subcutaneously, while the other three substances are administered intravenously via either central or peripheral vein. ICD-1O also includes three codes for non-specific approved monoclonal antibody substances via intravenous or subcutaneous injection. This will also allow for the coding of other monoclonal substances that may be developed in the future to treat COVID-19.

List of Monoclonal Antibodies Codes

The codes are:

XW013K6: Introduction of Leronlimab Monoclonal Antibody into Subcutaneous Tissue, Percutaneous Approach, New Technology Group 6

XW043E6: Introduction of Etesevimab Monoclonal Antibody into Central Vein, Percutaneous Approach, New Technology Group 6

XW033E6: Introduction of Etesevimab Monoclonal Antibody into Peripheral Vein, Percutaneous Approach, New Technology Group 6

XW033F6: Introduction of Bamlanivimab Monoclonal Antibody into Peripheral Vein, Percutaneous Approach, New Technology Group 6

XW043F6: Introduction of Bamlanivimab Monoclonal Antibody into Central Vein, Percutaneous Approach, New Technology Group 6

XW033G6: Introduction of REGN-COV2 Monoclonal Antibody into Peripheral Vein, Percutaneous Approach, New Technology Group 6

XW043G6: Introduction of REGN-COV2 Monoclonal Antibody into Central Vein, Percutaneous Approach, New Technology Group 6

XW033H6: Introduction of Other New Technology Monoclonal Antibody into Peripheral Vein, Percutaneous Approach, New Technology Group 6

XW043H6: Introduction of Other New Technology Monoclonal Antibody into Central Vein, Percutaneous Approach, New Technology Group 6

XW013H6: Introduction of Other New Technology Monoclonal Antibody into Subcutaneous Tissue, Percutaneous Approach, New Technology Group 6

Inpatient Codes for COVID-19 Vaccines

There are also six new codes for inpatient COVID-19 vaccination. Though it is anticipated that most vaccinations will occur outside the inpatient environment, the new ICD-10-PCS codes will allow for tracking of these vaccines on the inpatient record.

Since Medicare will reimburse for the vaccine and administration separately from the MS-DRG payment, the CPT vaccine codes will likely be used for Medicare patients who are inpatients. In addition, you can see the CMS website for more information (CMS, 2020).

New COVID-19 Vaccine Administration Codes

The ICD-10-PCS codes are subdivided based on the administration method: intramuscular or subcutaneous injection and whether this was the first, second, or single-dose/unspecified vaccinations.

XW013S6: Introduction of COVID-19 Vaccine Dose 1 into Subcutaneous Tissue, Percutaneous Approach, New Technology Group 6

XW013T6: Introduction of COVID-19 Vaccine Dose 2 into Subcutaneous Tissue, Percutaneous Approach, New Technology Group 6

XW013U6: Introduction of COVID-19 Vaccine into Subcutaneous Tissue, Percutaneous Approach, New Technology Group 6

XW023S6: Introduction of COVID-19 Vaccine Dose 1 into Muscle, Percutaneous Approach, New Technology Group 6

XW023T6: Introduction of COVID-19 Vaccine Dose 2 into Muscle, Percutaneous Approach, New Technology Group 6

XW023U6: Introduction of COVID-19 Vaccine into Muscle, Percutaneous Approach, New Technology Group 6

Other Specific Substances

Furthermore, CMS added five additional codes for two new substances. Baricitinib, which is administered orally or via a natural or artificial opening in the upper or lower GI system, and CD24Fc, which is administered intravenously.

XW0DXM6: Introduction of Baricitinib into Mouth and Pharynx, External Approach, New Technology Group 6

XW0G7M6: Introduction of Baricitinib into Upper GI, Via Natural or Artificial Opening, New Technology Group 6

XW0H7M6: Introduction of Baricitinib into Lower GI, Via Natural or Artificial Opening, New Technology Group 6

XW043L6: Introduction of CD24Fc Immunomodulator into Central Vein, Percutaneous Approach, New Technology Group 6

XW033L6: Introduction of CD24Fc Immunomodulator into Peripheral Vein, Percutaneous Approach, New Technology Group 6

Stay Tuned for More Updates

CMS will soon release updates to the ICD-10-CM Coding Guidelines and Addendum. More information on the use of both the diagnosis and procedure codes specific to COVID-19 is also forthcoming. Also, stay tuned to the YES Blog for important updates!

Additionally, in this unprecedented year for medical coding updates, coders may find it difficult to adjust to the changes. YES HIM Consulting’s education and coding support solutions are here to help coding teams navigate these changes. Contact YES today!
