Code Description

ICD-10 C82.93 is a billable code used to indicate a diagnosis of follicular lymphoma, unspecified, intra-abdominal lymph nodes.

Key Diagnostic Point:

Follicular lymphoma is a type of non-Hodgkin lymphoma characterized by the proliferation of follicle center (germinal center) B-cells. It is typically indolent, meaning it progresses slowly, and can present with a variety of symptoms. When classified as 'unspecified,' it indicates that the specific subtype or characteristics of the lymphoma have not been detailed. Intra-abdominal lymph nodes involvement suggests that the lymphoma has spread to lymph nodes located within the abdominal cavity, which can lead to symptoms such as abdominal pain, swelling, or discomfort. Diagnosis often involves imaging studies, such as CT scans, and biopsy of affected lymph nodes. Staging is crucial for determining the extent of the disease and guiding treatment options, which may include watchful waiting, chemotherapy, immunotherapy, or radiation therapy. B-symptoms, which include fever, night sweats, and weight loss, may also be present and are important for assessing disease severity.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of lymphomas, improving the accuracy of data collection and treatment tracking. C82.93 provides a clear designation for cases where the lymphoma is unspecified, but still requires careful documentation to ensure appropriate treatment and reimbursement.

ICD-9 vs ICD-10
