What This Code Means
B97.10 is the ICD-10-CM diagnosis code for unspecified enterovirus as the cause of diseases classified elsewhere. An unspecified enterovirus (a type of virus that affects the digestive system and other areas) is identified as causing a disease classified elsewhere. The specific type of enterovirus is not documented. B97.10 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).
B97.10 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.
Use only when the enterovirus is confirmed but the specific type cannot be determined.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B97.10 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use only when the enterovirus is confirmed but the specific type cannot be determined
- •Code the primary condition first, then use this as a secondary code to identify the viral cause
