B08.22
BillableExanthema subitum [sixth disease] due to human herpesvirus 7
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Exanthema subitum, also known as sixth disease, is a viral infection caused by human herpesvirus 7 that primarily affects infants and young children, characterized by high fever followed by a distinctive pink rash that appears as the fever subsides. This is a self-limiting condition that typically resolves without complications.
Coding Tips
- •Ensure documentation clearly specifies that human herpesvirus 7 (HHV-7) is the causative agent, as B08.21 is used for HHV-6 and B08.22 is specific to HHV-7
- •This code should only be assigned when the rash (exanthema subitum) is present; if only fever without the characteristic rash is documented, consider alternative coding
