ICD-10 Code C81.36 – Lymphocyte depleted Hodgkin lymphoma, intrapelvic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.36 – Lymphocyte depleted Hodgkin lymphoma, intrapelvic lymph nodes
What it is
This code identifies lymphocyte-depleted Hodgkin lymphoma located in the intrapelvic lymph nodes. It is used when the pathology or oncology record specifies this subtype and nodal site.
Clinical signs
Findings may include enlarged pelvic lymph nodes and other lymphoma-related features such as unexplained weight loss, fever, or night sweats. Clinical features vary; refer to documentation.
When to use this code
Use C81.36 when the provider documents lymphocyte-depleted Hodgkin lymphoma involving intrapelvic lymph nodes. It may appear in biopsy, oncology, or staging records when the disease site is clearly identified. Check documentation if the subtype or nodal region is not explicit.
Do not use for
Do not use this code for other Hodgkin lymphoma subtypes, non-Hodgkin lymphomas, or generalized lymph node involvement without an intrapelvic site. Check documentation if the record is nonspecific.
Coding tip
Assign the code only when both the lymphocyte-depleted subtype and intrapelvic nodal location are documented.
