What This Code Means
B97.89 is the ICD-10-CM diagnosis code for other viral agents as the cause of diseases classified elsewhere. Other viral agents not specifically classified are identified as the underlying cause of another disease or condition being treated. B97.89 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).
B97.89 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
This is a catch-all code for viral agents that don't fit into the more specific B97 subcategories; use only when a more specific viral code is unavailable.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for B97.89 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a catch-all code for viral agents that don't fit into the more specific B97 subcategories; use only when a more specific viral code is unavailable
- •Always pair with the primary diagnosis code describing the actual disease or condition caused by the unspecified viral agent
