ICD-10 Code C81.09 – Nodular lymphocyte predominant Hodgkin lymphoma, extranodal and solid organ sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.09 – Nodular lymphocyte predominant Hodgkin lymphoma, extranodal and solid organ sites
What it is
C81.09 identifies nodular lymphocyte predominant Hodgkin lymphoma involving extranodal or solid organ sites. Use it when the diagnosis specifically documents this lymphoma subtype outside the lymph nodes.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe an indolent Hodgkin lymphoma with lymph node or extranodal involvement, often confirmed by pathology and imaging.
When to use this code
Use this code when the provider documents nodular lymphocyte predominant Hodgkin lymphoma in an extranodal site or solid organ, such as spleen or other non-nodal tissue. Code from the confirmed site description in the record. If the site is not specified, check documentation.
Do not use for
Do not use this code for classical Hodgkin lymphoma or for nodular lymphocyte predominant Hodgkin lymphoma limited to lymph nodes. If the record does not clearly show extranodal or solid organ involvement, check documentation.
Coding tip
Match the code to both the lymphoma subtype and the documented anatomic site; missing site detail can change code selection.
