ICD-10 Code C82.83 – Other types of follicular lymphoma, intra-abdominal lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.83 – Other types of follicular lymphoma, intra-abdominal lymph nodes
What it is
This code identifies follicular lymphoma involving intra-abdominal lymph nodes, excluding the more specific follicular lymphoma subtypes listed elsewhere. Use it when the record documents this lymphoma site and type.
Clinical signs
Clinical features vary; refer to documentation. Common findings in lymphoma may include enlarged lymph nodes, abdominal discomfort, or symptoms related to mass effect, but confirmation depends on pathology and clinical records.
When to use this code
Use C82.83 when the provider documents other types of follicular lymphoma with intra-abdominal lymph node involvement. It fits cases where the histology is follicular lymphoma and the site is abdominal nodal disease. Check documentation if the record names a different follicular lymphoma subtype or a non-nodal primary site.
Do not use for
Do not use this code for non-follicular lymphomas, unspecified lymphoma, or follicular lymphoma at a different lymph node region. If the site or subtype is unclear, check documentation.
Coding tip
Confirm both the follicular lymphoma subtype and the intra-abdominal nodal site before assigning C82.83.
