2025 ICD-10-CM code C85.8
Other specified types of non-Hodgkin lymphoma.
Medical necessity for treatments related to C85.8 must be supported by documentation of the diagnosis, staging, and treatment plan.This typically includes biopsy reports confirming the diagnosis and imaging or other tests to assess the extent of the disease.The chosen treatment approach should align with established guidelines for rare or unspecified NHL subtypes.
Diagnosis and management of this condition falls under the purview of hematologists-oncologists or medical oncologists.They determine the specific treatment strategy (watchful waiting, chemotherapy, radiation therapy, immunotherapy, targeted therapy, stem cell transplant) based on the subtype, stage, and patient's overall health. Regular follow-up and surveillance are essential for monitoring disease progression or recurrence.
In simple words: This code indicates a specific type of Non-Hodgkin's lymphoma (a cancer of the lymphatic system).It's used when the more common types of NHL have been ruled out and testing identifies an unusual variation.
This code represents a diagnosis of non-Hodgkin lymphoma (NHL) that is not specifically classified under other codes within the C81-C96 range.It encompasses various less common or unique forms of NHL that don't fit established categories.The diagnosis requires confirmation through microscopic examination and immunophenotyping to distinguish it from other lymphomas and related conditions.
Example 1: A patient presents with enlarged lymph nodes and B symptoms. Biopsy and immunohistochemistry reveal an unusual NHL subtype not fitting typical classifications. C85.8 is assigned., A patient with a prior history of follicular lymphoma develops a new type of NHL during follow up.After extensive workup, the new lymphoma is determined to be a rare variant.C85.8 is used to reflect the change in diagnosis., A patient undergoes a lymph node biopsy for suspected lymphoma. Pathological analysis identifies an unusualNHL type with distinct genetic characteristics not corresponding to other classified NHLs.In the absence of a more specific code, C85.8 is assigned.
Documentation must include details of the diagnostic workup, including biopsy results, immunophenotyping studies, imaging findings, and other pertinent lab results to support the diagnosis of a non-specified NHL. Clinical presentation, disease stage, treatment plan, and response to therapy should also be documented.
