What This Code Means

A type of Hodgkin lymphoma with mostly lymphocytes that has spread to lymph nodes in the abdomen.

Coding Tips

•Verify the pathology report confirms lymphocyte-rich subtype before coding
•Ensure documentation specifies intra-abdominal location; do not assume based on symptoms alone

Clinical Significance

Lymphocyte-rich Hodgkin lymphoma with intra-abdominal lymph node involvement represents an uncommon location for this favorable-prognosis subtype. Abdominal nodal involvement may indicate more advanced staging and can present with nonspecific symptoms including abdominal discomfort, early satiety, or constitutional B symptoms. The generally favorable biology of this subtype often leads to good outcomes even with abdominal disease.

Documentation Requirements

✓Pathology confirming lymphocyte-rich classical Hodgkin lymphoma
✓Imaging confirming intra-abdominal lymph node involvement (para-aortic, mesenteric, celiac, retroperitoneal)
✓Clear distinction from intrapelvic nodes which are below the pelvic brim
✓Staging documentation including all involved sites
✓Provider management plan during the encounter

Commonly Confused Codes

C81.46 — Lymphocyte-rich Hodgkin lymphoma, intrapelvic: abdominal nodes are above the pelvic brim; pelvic nodes are below it C81.47 — Lymphocyte-rich Hodgkin lymphoma, spleen: splenic involvement is coded separately from abdominal node involvement C81.23 — Mixed cellularity Hodgkin lymphoma, intra-abdominal: same location but different subtype; verify pathology
