SARS-associated coronavirus causing diseases classd elswhr

This code identifies a patient's condition where SARS-associated coronavirus is confirmed as the underlying cause of a disease that is classified under a different ICD-10-CM code. It signifies the etiologic agent responsible for a manifestation elsewhere in the classification system, excluding direct respiratory involvement.

Use this code when documentation specifies a disease, such as myocarditis or encephalitis, is directly caused by SARS-associated coronavirus, and the primary condition is coded separately. The medical record should clearly state the causal link between the SARS-associated coronavirus and the other classified disease.

• Always sequence this code as a secondary diagnosis, following the code for the specific disease caused by the SARS-associated coronavirus.
• Do not use this code if the patient has pneumonia due to SARS-associated coronavirus; instead, use J12.81.
• Ensure physician documentation explicitly links the SARS-associated coronavirus as the etiology for the co-occurring condition.
