Lymphocyte-rich Hodgkin lymphoma, unspecified site

This code identifies a specific subtype of Hodgkin lymphoma characterized by an abundance of lymphocytes and a paucity of Reed-Sternberg cells. It represents a diagnosis of lymphocyte-rich classical Hodgkin lymphoma without specifying the primary anatomical location of the disease.

Use this code when the pathology report definitively diagnoses lymphocyte-rich Hodgkin lymphoma, and the medical record does not specify the primary site of involvement. This diagnosis is typically confirmed through biopsy and immunohistochemical staining.

• Ensure the pathology report explicitly states "lymphocyte-rich" Hodgkin lymphoma; do not assume based on other findings.
• If a specific anatomical site is documented (e.g., lymph nodes of the neck), a more specific code from the C81.4- subcategory should be used.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by codes for any associated symptoms or complications.
