ICD-10 Code C81.77 – Other Hodgkin lymphoma, spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.77 – Other Hodgkin lymphoma, spleen
What it is
C81.77 identifies Hodgkin lymphoma involving the spleen when the record specifies an “other” Hodgkin lymphoma subtype. Use it for documented splenic involvement, not for unspecified lymphoma or non-Hodgkin disease.
Clinical signs
Clinical features vary; refer to documentation. Splenic involvement may be noted on imaging, pathology, or staging workup, and patients can have splenomegaly or systemic lymphoma findings.
When to use this code
Use this code when the provider documents other Hodgkin lymphoma affecting the spleen, including cases where the spleen is a confirmed involved site. It is appropriate when the record clearly identifies Hodgkin lymphoma and splenic involvement together. Check documentation if the subtype or site is not explicit.
Do not use for
Do not use it for Hodgkin lymphoma without splenic involvement, or for unspecified lymphoma types. It is also incorrect for non-Hodgkin lymphoma or when the chart does not support a specific splenic site.
Coding tip
Confirm both the Hodgkin subtype and the spleen as the documented site before assigning C81.77.
