ICD-10 Code C81.4 – Lymphocyte-rich Hodgkin lymphoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.4 – Lymphocyte-rich Hodgkin lymphoma
What it is
C81.4 identifies lymphocyte-rich Hodgkin lymphoma, a subtype of classic Hodgkin lymphoma. Use it when documentation specifies this histology rather than another Hodgkin or non-Hodgkin type.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include enlarged lymph nodes and pathology confirming lymphocyte-rich Hodgkin lymphoma.
When to use this code
Use C81.4 when the provider documents lymphocyte-rich Hodgkin lymphoma, whether newly diagnosed or established. It is appropriate for pathology-confirmed cases and for encounters focused on this specific lymphoma subtype. Check documentation if the record only says Hodgkin lymphoma without subtype.
Do not use for
Do not use this code for other Hodgkin lymphoma subtypes, unspecified Hodgkin lymphoma, or non-Hodgkin lymphoma. If the subtype is not documented, use the unspecified code instead.
Coding tip
Code the exact lymphoma subtype from the pathology or oncology note, and query for clarification when the subtype is missing.
