ICD-10 Code C81.44 – Lymphocyte-rich Hodgkin lymphoma, lymph nodes of axilla and upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.44 – Lymphocyte-rich Hodgkin lymphoma, lymph nodes of axilla and upper limb
What it is
This code identifies lymphocyte-rich Hodgkin lymphoma involving lymph nodes in the axilla or upper limb. Use it when the diagnosis specifies this subtype and the nodal site is documented.
Clinical signs
Clinical features vary; refer to documentation. Hodgkin lymphoma may present with enlarged lymph nodes, often painless, and may include systemic “B” symptoms such as fever, night sweats, or weight loss.
When to use this code
Use C81.44 when the provider documents lymphocyte-rich Hodgkin lymphoma and clearly localizes it to axillary or upper-limb lymph nodes. Apply it for confirmed diagnoses, pathology-supported assessments, or discharge summaries that name this exact site and subtype.
If the record only says Hodgkin lymphoma without subtype or nodal location, check documentation before coding. Do not assume the axilla or upper limb based on imaging alone.
Do not use for
Do not use this code for other Hodgkin lymphoma subtypes, unspecified nodal sites, or non-Hodgkin lymphomas. Check documentation if the site is mediastinal, cervical, or otherwise different.
Coding tip
Code only when both the lymphocyte-rich subtype and axillary or upper-limb node involvement are documented together.
