B97.21
BillableSARS-associated coronavirus as the cause of diseases classified elsewhere
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code indicates that a disease or condition was caused by the SARS coronavirus (the virus responsible for the 2003 SARS outbreak). It is used as a secondary code to identify the infectious cause when the main diagnosis code describes the specific disease or complication that resulted from the SARS infection.
Coding Tips
- •This is a secondary code that must be paired with a primary diagnosis code describing the actual disease or condition caused by SARS (such as pneumonia, respiratory failure, or other manifestations)
- •Use this code only when SARS coronavirus is confirmed as the causative agent; do not use for COVID-19 (caused by SARS-CoV-2), which has separate ICD-10-CM codes
Excludes 1 — Do NOT code together
- pneumonia due to SARS-associated coronavirus (J12.81)
