0.000What This Code Means
A type of Hodgkin lymphoma that has spread to organs outside the lymph node system, such as the liver, lungs, or bone.
Coding Tips
- •Document the specific extranodal site(s) involved in the medical record for clinical clarity
- •This code indicates more advanced disease; verify staging information is documented
Clinical Significance
Other Hodgkin lymphoma with extranodal and solid organ involvement represents stage IV disease from an uncommon histologic variant. Organ involvement such as liver, lung, bone, or bone marrow significantly impacts prognosis and drives intensive systemic treatment. The 'other' subtype designation may prompt expert pathology consultation to better characterize the variant for treatment optimization.
Documentation Requirements
- ✓Pathology confirming Hodgkin lymphoma classified as 'other' subtype
- ✓Documentation of specific extranodal organ(s) involved with imaging or biopsy confirmation
- ✓Stage IV designation reflecting organ involvement
- ✓Bone marrow biopsy results if marrow involvement is suspected
- ✓Active treatment documentation and encounter-specific assessment
Commonly Confused Codes
C81.77 — Other Hodgkin lymphoma, spleen: use C81.77 specifically for splenic disease; C81.79 covers other extranodal organsC81.78 — Other Hodgkin lymphoma, multiple lymph node sites: C81.78 is for multi-site nodal disease; C81.79 is for organ involvementC78-C79 — Secondary malignant neoplasm codes: lymphoma organ involvement is coded as primary lymphoma, not secondary neoplasm
