B97.0 ICD-10-CM Code: Adenovirus as the cause of diseases classified elsewhere

B97.0 is the ICD-10-CM diagnosis code for adenovirus as the cause of diseases classified elsewhere. This code indicates that an adenovirus infection is the underlying cause of another disease or condition that is being treated. It is used as a secondary code to identify the specific virus responsible when a patient has a viral infection affecting various body systems. B97.0 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering bacterial and viral infectious agents (b95-b97).

B97.0 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This is a secondary code that must be paired with a primary diagnosis code describing the actual disease or condition caused by the adenovirus (such as respiratory infection, conjunctivitis, or gastroenteritis).
