B97.39 ICD-10-CM Code: Other retrovirus as the cause of diseases classified elsewhere

B97.39 is the ICD-10-CM diagnosis code for other retrovirus as the cause of diseases classified elsewhere. This code identifies a retrovirus (a type of virus that includes HIV and similar viruses) other than HIV as the underlying cause of a disease or condition documented in the patient's medical record. It is used as a secondary code to indicate the infectious agent responsible for the patient's illness. B97.39 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).

B97.39 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 cause-of-disease code and should be used as a secondary diagnosis code paired with the primary condition it caused; never use it as the primary diagnosis.
