Other human herpesviruses (B10)

B10 codes cover infections caused by less common human herpesviruses, including specific types like human herpesvirus 6 and 7. These codes are used for diagnosing viral infections such as encephalitis and other tissue involvement related to these viruses.

The B10 category includes conditions like other human herpesvirus encephalitis (B10.0), with more specific codes for human herpesvirus 6 encephalitis (B10.01) and other herpesvirus encephalitis including human herpesvirus 7 and 8 (B10.09). These viruses, also known as Roseolovirus, can cause viral brain inflammation and other serious complications. Additionally, codes B10.8x identify various infections from human herpesvirus 6 and 7 affecting the skin or other organs, and B10.89 captures infections linked to human herpesvirus 8, which is associated with conditions like Castleman disease and Kaposi's sarcoma. These codes help healthcare professionals specify and track these less common herpesvirus infections for accurate diagnosis and treatment planning.

Instructional Notations

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Castleman Disease

Large benign, hyperplastic lymph nodes. The more common hyaline vascular subtype is characterized by small hyaline vascular follicles and interfollicular capillary proliferations. Plasma cells are often present and represent another subtype with the plasma cells containing IgM and IMMUNOGLOBULIN A.
