ICD-10 Code C81.75 – Other Hodgkin lymphoma, lymph nodes of inguinal region and lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.75 – Other Hodgkin lymphoma, lymph nodes of inguinal region and lower limb
What it is
This code identifies Hodgkin lymphoma classified as “other” and involving lymph nodes in the inguinal region or lower limb. Use it when the record specifies this nodal location and does not fit a more specific Hodgkin lymphoma subtype.
Clinical signs
Clinical features vary; refer to documentation. Hodgkin lymphoma commonly presents with enlarged lymph nodes, and inguinal or lower-limb nodes may be noted on exam or imaging, with diagnosis confirmed by pathology.
When to use this code
Use this code when the provider documents Hodgkin lymphoma affecting inguinal or lower-extremity lymph nodes and specifies the “other” category. It is appropriate for confirmed disease in those nodes, whether initial diagnosis, active treatment, or follow-up documentation supports the location.
Do not use for
Do not use it for non-Hodgkin lymphoma, unspecified lymph node sites, or generalized Hodgkin lymphoma without location detail. Check documentation if the record only mentions enlarged nodes or a suspected lymphoma.
Coding tip
Code the documented nodal site exactly; if the site is unclear, query for specificity before assigning C81.75.
