ICD-10 Code C81.06 – Nodular lymphocyte predominant Hodgkin lymphoma, intrapelvic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.06 – Nodular lymphocyte predominant Hodgkin lymphoma, intrapelvic lymph nodes
What it is
This code identifies nodular lymphocyte predominant Hodgkin lymphoma involving intrapelvic lymph nodes. It is a specific lymphoma diagnosis, not a general lymph node enlargement code.
Clinical signs
Clinical features vary; refer to documentation. Patients may have enlarged pelvic lymph nodes confirmed by pathology, imaging, or both, with lymphoma subtype documented as nodular lymphocyte predominant Hodgkin lymphoma.
When to use this code
Use C81.06 when the record clearly states nodular lymphocyte predominant Hodgkin lymphoma in intrapelvic lymph nodes. Apply it for confirmed primary or involved pelvic nodal disease, not for suspected lymphoma. If the site or subtype is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for unspecified Hodgkin lymphoma, other lymphoma subtypes, or nonmalignant pelvic lymphadenopathy. Check documentation if the pathology report does not confirm nodular lymphocyte predominant Hodgkin lymphoma.
Coding tip
Code the documented subtype and nodal location together; if either element is missing, query the record.
