Other non-follicular lymphoma, unspecified site

This diagnosis code signifies a malignant lymphoma that does not originate from follicular centers and is not further specified as a particular subtype. It represents a broad category of non-Hodgkin lymphomas that are not otherwise classified or detailed in the medical record.

Use this code when the medical record clearly indicates a diagnosis of non-follicular lymphoma, but the specific subtype (e.g., diffuse large B-cell lymphoma, mantle cell lymphoma) is not documented, or the physician has not yet determined the exact classification. This code is appropriate when the anatomical site of the lymphoma is also not specified.

• Avoid using this code if a more specific subtype of non-follicular lymphoma (e.g., C83.3- for diffuse large B-cell lymphoma) is documented.
• Always query the provider for a more specific diagnosis if possible, including the specific subtype and anatomical site.
• This code should be used as a last resort when no further specificity can be obtained from the medical record.
