0.000What This Code Means
A type of cancer affecting B-cells that has spread to organs or tissues outside the lymph node system.
Coding Tips
- •Document the specific extranodal sites involved (e.g., liver, bone marrow, GI tract) in the medical record
- •This code indicates more advanced disease; ensure staging information is documented
Clinical Significance
Small cell B-cell lymphoma of extranodal and solid organ sites indicates disease beyond the lymph node system, such as involvement of the gastrointestinal tract, liver, bone marrow, or other organs. Extranodal involvement typically signifies more advanced disease and may require different treatment approaches than purely nodal disease.
Documentation Requirements
- ✓Pathology confirmation from the specific extranodal site (biopsy of involved organ)
- ✓Documentation of the specific extranodal organ(s) involved
- ✓Imaging confirming solid organ involvement (CT, PET/CT, MRI)
- ✓Bone marrow biopsy results if bone marrow involvement is suspected
- ✓Staging documentation reflecting extranodal disease (E designation in Ann Arbor staging)
Commonly Confused Codes
C83.07 — Spleen; splenic involvement has its own specific code and should not be coded as extranodalC83.08 — Multiple lymph node sites; this is for nodal disease only, while C83.09 captures non-nodal organ involvementC83.00 — Unspecified site; use C83.09 when extranodal involvement is documented, not when site is simply unknown
