Nodlr lymphocy predom Hdgkn lymph, nodes of head, face, & nk

This diagnosis code specifies a rare, indolent subtype of Hodgkin lymphoma characterized by a nodular growth pattern and the presence of "popcorn" cells (lymphocyte-predominant cells). It indicates that the disease is localized to the lymph nodes located in the head, face, or neck regions.

This code is appropriate for patients diagnosed with nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) where imaging or biopsy confirms involvement of cervical, supraclavicular, preauricular, or other head/neck lymph nodes. Documentation should clearly state the specific subtype of Hodgkin lymphoma and the anatomical location of the affected lymph nodes.

• Ensure the pathology report explicitly states "nodular lymphocyte predominant Hodgkin lymphoma" to differentiate from classical Hodgkin lymphoma subtypes.
• Verify the anatomical site of involvement; this code is specific to head, face, and neck lymph nodes.
• Do not confuse with C81.1- (classical Hodgkin lymphoma, nodular sclerosis) or other Hodgkin lymphoma subtypes.
