Other specified and unspecified types of non-Hodgkin lymphoma (C85) ICD-10-CM
The C85 code range covers other specified and unspecified types of non-hodgkin lymphoma with 49 ICD-10-CM diagnosis codes. 44 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.

About the C85 Code Range
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."
