About U07.1

U07.1 is the ICD-10-CM diagnosis code for COVID-19. It belongs to category U07 (emergency use of U07), block U00-U49 (Provisional assignment of new diseases of uncertain etiology or emergency use) and chapter 22 (codes for special purposes). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within U07 (emergency use of U07), U07.1 is specifically for COVID-19. Related codes cover Vaping-related disorder (U07.0).

The conditions in its Excludes2 note aren't part of U07.1, but may be coded alongside it if the patient has both: coronavirus as the cause of diseases classified elsewhere (B97.2-) and pneumonia due to SARS-associated coronavirus (J12.81).

Use an additional code to identify pneumonia or other manifestations, such as: pneumonia due to COVID-19 (J12.82). Use an additional code, if applicable, for associated conditions such as: COVID-19 associated coagulopathy (D68.8), disseminated intravascular coagulation (D65), hypercoagulable states (D68.69) and thrombophilia (D68.69).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 177 (Respiratory Infections and Inflammations with MCC, relative weight 1.6092), DRG 178 (Respiratory Infections and Inflammations with CC, relative weight 0.9744), DRG 179 (Respiratory Infections and Inflammations without CC/MCC, relative weight 0.7345), DRG 791 (Prematurity with Major Problems, relative weight 4.1075), DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506) and 2 more, in MDC 04 (Diseases and Disorders of the Respiratory System), MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It was added in FY2021, effective October 1, 2020.
