C83: Non-follicular lymphoma

C83 refers to Non-follicular lymphoma, a classification of cancers that affect the lymphatic system, bone marrow, and blood-forming tissues. These hematologic malignancies vary by cell origin—B-cell, T-cell, plasma cell, or myeloid—and range in severity and progression. Accurate ICD10 coding is crucial for tracking disease subtype, progression, and treatment response.

Symptoms

• Swollen lymph nodes – Often painless, in neck, armpit, or groin
• Fatigue – Due to anemia or bone marrow suppression
• Fever or night sweats – Common systemic “B symptoms”
• Unexplained weight loss – A key warning sign in blood cancers
• Bleeding or bruising – Due to low platelet count in leukemia
• Frequent infections – From low white blood cell counts
• Bone pain – Especially in multiple myeloma

Diagnosis

Diagnosis of Non-follicular lymphoma includes blood tests (CBC, flow cytometry), bone marrow biopsy, lymph node biopsy, and imaging (CT, PET scans). Genetic and immunophenotyping studies help classify the specific subtype and guide targeted therapies. Monitoring may also involve minimal residual disease (MRD) testing.

ICD10 Code Usage

ICD10 code C83 is used in hematology and oncology for classifying and managing lymphomas, leukemias, and other blood cancers. These codes support documentation for cancer registries, clinical trials, insurance billing, and multidisciplinary treatment planning.
