What This Code Means

A rare type of Hodgkin lymphoma (lymphocyte depleted variant) affecting lymph nodes within the pelvis.

Coding Tips

•Ensure the site is specifically documented as intrapelvic lymph nodes
•Distinguish from other pelvic malignancies that may involve lymph nodes secondarily

Clinical Significance

Lymphocyte depleted Hodgkin lymphoma affecting intrapelvic lymph nodes is an extremely rare presentation of the most aggressive classical Hodgkin subtype. Intrapelvic nodal disease may cause urinary or lower extremity symptoms due to mass effect. These patients require comprehensive staging and aggressive systemic therapy given the poor prognostic implications of this histologic subtype.

Documentation Requirements

✓Pathology confirming lymphocyte depleted Hodgkin lymphoma subtype
✓Imaging (CT or PET/CT) confirming intrapelvic lymph node involvement (iliac, obturator, or presacral nodes)
✓Clear distinction from inguinal nodes (superficial groin) and intra-abdominal nodes (above the pelvic brim)
✓Staging documentation and treatment plan
✓Encounter-specific provider assessment

Commonly Confused Codes

C81.35 — Lymphocyte depleted Hodgkin lymphoma, inguinal/lower limb: inguinal nodes are in the groin crease and superficial; intrapelvic nodes are internal within the pelvic cavity C81.33 — Lymphocyte depleted Hodgkin lymphoma, intra-abdominal: the boundary between abdominal and pelvic nodes is the pelvic brim at approximately the L5-S1 level C81.26 — Mixed cellularity Hodgkin lymphoma, intrapelvic: same site but different histologic subtype — verify pathology
