0.000What This Code Means
A type of cancer affecting B-cells (immune cells) in the spleen, characterized by small-sized cancer cells.
Coding Tips
- •Verify documentation specifies spleen involvement; do not assume if only 'small cell B-cell lymphoma' is documented
- •Confirm whether patient is in remission; if so, use C83.0A instead
Clinical Significance
Small cell B-cell lymphoma of the spleen represents an important extranodal site that may present with splenomegaly, cytopenias, or constitutional symptoms. Splenic involvement often indicates disseminated disease and may warrant splenectomy for both diagnostic and therapeutic purposes, impacting long-term infection risk management.
Documentation Requirements
- ✓Histological confirmation via splenectomy specimen, splenic biopsy, or flow cytometry
- ✓Imaging documenting splenic involvement (splenomegaly, focal lesions on CT/PET)
- ✓Complete blood count documenting any cytopenias related to splenic disease
- ✓Documentation of whether splenectomy was performed
- ✓Post-splenectomy vaccination status if applicable
Commonly Confused Codes
C83.03 — Intra-abdominal lymph nodes; the spleen is a solid organ, not a lymph node, and has its own codeC83.09 — Extranodal/solid organ sites; use C83.07 specifically when the spleen is the documented siteC83.0A — In remission; use only when remission is explicitly documented, not when spleen has been removedD73.1 — Hypersplenism; this is a functional disorder, not a neoplastic diagnosis
