0.000What This Code Means
A type of blood cancer affecting immature lymphoid cells that involves lymph nodes in multiple different locations throughout the body.
Coding Tips
- •Use this code only when documentation clearly indicates involvement of lymph nodes at two or more separate anatomical sites
- •Do not use if only one site is involved; select the specific site code instead
Clinical Significance
Lymphoblastic lymphoma involving multiple lymph node sites indicates advanced, disseminated disease which is the typical presentation for this aggressive lymphoma. Multi-site involvement necessitates intensive ALL-type chemotherapy regimens and carries prognostic implications. Complete staging is essential to document all involved regions.
Documentation Requirements
- ✓Pathology-confirmed lymphoblastic lymphoma with lineage determination
- ✓Documentation of at least two distinct lymph node regions involved
- ✓PET/CT or CT staging documenting all involved sites
- ✓Bone marrow biopsy results
- ✓CNS evaluation (lumbar puncture with CSF analysis)
Commonly Confused Codes
C83.50 — Lymphoblastic lymphoma, unspecified; use C83.58 when multiple specific sites are documentedC83.59 — Extranodal/solid organ sites; C83.58 is for multiple nodal sites, not organ involvementC91.00 — Acute lymphoblastic leukemia; bone marrow blasts >25% designates leukemiaC83.38 — DLBCL, multiple sites; different, mature B-cell lymphoma
