Lymphocyte-rich Hodgkin lymphoma, intrathoracic lymph nodes

This diagnosis code signifies a specific subtype of Hodgkin lymphoma, characterized by a predominance of lymphocytes and affecting lymph nodes located within the chest cavity. It represents a less common form of classical Hodgkin lymphoma, often associated with a favorable prognosis.

Use this code when documentation explicitly states a diagnosis of "lymphocyte-rich Hodgkin lymphoma" and specifies involvement of intrathoracic lymph nodes (e.g., mediastinal, hilar, or paratracheal lymph nodes). This diagnosis is typically confirmed by biopsy and histopathological examination.

• Ensure the pathology report clearly identifies the "lymphocyte-rich" subtype of Hodgkin lymphoma.
• Verify that the anatomical site is specifically documented as "intrathoracic lymph nodes" to differentiate from other nodal sites.
• Do not confuse with nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL), which is a distinct entity.
