What This Code Means

B34.4 is the ICD-10-CM diagnosis code for papovavirus infection, unspecified. A viral infection caused by papovavirus, a group of viruses that can cause various infections. The specific location or type of infection is not specified. B34.4 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering other viral diseases (b25-b34).

B34.4 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 non-specific code for papovavirus infections without documented site information.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B34.4 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
