What This Code Means
B00.89 is the ICD-10-CM diagnosis code for other herpesviral infection. This code describes herpesviral infections caused by herpes simplex virus (HSV) that don't fit into the more common categories like oral herpes or genital herpes. These are less typical presentations of herpes infections affecting various parts of the body. B00.89 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering viral infections characterized by skin and mucous membrane lesions (b00-b09).
B00.89 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 this code only when the herpesviral infection site or type is not specified by more specific B00 codes (B00.1 for genital, B00.7 for disseminated, etc.); always review documentation for anatomical location to assign the most specific code.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B00.89 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the herpesviral infection site or type is not specified by more specific B00 codes (B00.1 for genital, B00.7 for disseminated, etc.); always review documentation for anatomical location to assign the most specific code
- •This is an 'other' category code, so ensure that more specific herpesviral infection codes have been ruled out before assigning B00.89; document the specific site or nature of infection in the medical record for clarity
