ICD-10 Code C81.04 – Nodular lymphocyte predominant Hodgkin lymphoma, lymph nodes of axilla and upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.04 – Nodular lymphocyte predominant Hodgkin lymphoma, lymph nodes of axilla and upper limb
What it is
This code identifies nodular lymphocyte predominant Hodgkin lymphoma involving lymph nodes in the axilla or upper limb. Use it when documentation specifies this lymphoma subtype and the affected nodal region.
Clinical signs
Clinical features vary; refer to documentation. Commonly, patients present with enlarged lymph nodes in the axilla or upper limb region, and diagnosis is confirmed by pathology.
When to use this code
Use C81.04 when the provider documents nodular lymphocyte predominant Hodgkin lymphoma and names axillary or upper-limb lymph nodes as the site. You may use it for confirmed diagnoses, including pathology-supported cases. Check documentation if the site is described differently or if multiple nodal regions are involved.
Do not use for
Do not use this code for other Hodgkin lymphoma subtypes or for lymphomas without a documented nodular lymphocyte predominant pattern. Do not assign it when the involved nodes are elsewhere unless the record supports this site.
Coding tip
Match both the lymphoma subtype and the exact nodal location in the chart before coding.
