Other specified and unspecified types of non-Hodgkin lymphoma (C85)
The ICD-10 code C85 covers various other specified and unspecified types of non-Hodgkin lymphoma, a group of diverse blood cancers affecting lymphatic tissues. This includes subcategories like unspecified B-cell lymphoma and mediastinal (thymic) large B-cell lymphoma, with distinctions by site and remission status.
These codes help classify less common or unspecified forms of non-Hodgkin lymphoma beyond the main defined categories. For example, C85.10 relates to unspecified B-cell lymphoma at any unspecified site and includes conditions often known as high-grade or low-grade B-cell lymphomas, primary cutaneous B-cell lymphoma, and rare types such as plasmablastic lymphoma. The section also includes specified types involving particular lymph node regions or organs, as well as mediastinal large B-cell lymphoma (C85.2 series). Other specified types in C85.8 cover diverse lymphomas like nodular, follicular, or diffuse types affecting various body parts such as the spleen, lymph nodes of head, or extranodal tissues. Codes ending with "9" denote unspecified non-Hodgkin lymphoma, further differentiated by site and remission. Understanding the synonyms linked with these codes aids accurate clinical documentation and coding when conditions are described under alternative names like "nodular lymphoma" or "lymphosarcoma."

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
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.
Plasmablastic Lymphoma
Malignant lymphoma composed of large B lymphoid cells which have the immunophenotype of plasma cells and a predilection for the ORAL CAVITY.
