2025 ICD-10-CM code B97.21
(Active) Effective Date: N/A Infectious and parasitic diseases - Bacterial and viral infectious agents Certain infectious and parasitic diseases Feed
SARS-associated coronavirus as the cause of diseases classified elsewhere.
Medical necessity is established by the diagnosis of a condition caused by the SARS-associated coronavirus.
A virus is an infectious agent. SARS-associated coronavirus causes severe acute respiratory syndrome (SARS) and is typically transmitted through respiratory droplets and close contact. Symptoms, diagnostic studies and procedures, and treatment depend on the disease.
In simple words: This code is used when a person has a disease caused by the SARS-associated coronavirus. It's used with another code that describes the specific disease the person has.It helps track how often the virus causes different illnesses.
This code identifies SARS-associated coronavirus as the cause of a disease classified elsewhere. Use this code in conjunction with other code(s) identifying the disease(s) or condition(s). This code should not be used as the first-listed or principal diagnosis but should follow the disease or condition code(s).
Example 1: A patient presents with pneumonia confirmed to be caused by SARS-associated coronavirus. The primary code would be for the pneumonia (J12.81), followed by B97.21 to specify the viral cause., A patient with a pre-existing heart condition develops myocarditis, which is subsequently determined to be caused by SARS-associated coronavirus.The code for myocarditis would be listed first, followed by B97.21., A patient presents with acute bronchitis, and tests confirm the presence of SARS-associated coronavirus as the causative agent.The appropriate code for bronchitis (J20.-) is used first, with B97.21 as a secondary code.
Documentation should clearly indicate the causal relationship between the SARS-associated coronavirus and the diagnosed condition. Laboratory confirmation of the virus through diagnostic testing is ideal.
