C81.4Lymphocyte-rich Hodgkin lymphoma

C81.4 is the ICD-10-CM diagnosis code for Lymphocyte-rich Hodgkin lymphoma. It belongs to category C81 (Hodgkin lymphoma), block C81-C96 (malignant neoplasms of lymphoid, hematopoietic and related tissue) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 11 subcodes must be used instead.

Within C81 (Hodgkin lymphoma), C81.4 is specifically for Lymphocyte-rich Hodgkin lymphoma. Related codes cover nodular lymphocyte predominant Hodgkin lymphoma (C81.0), nodular sclerosis Hodgkin lymphoma (C81.1), mixed cellularity Hodgkin lymphoma (C81.2), lymphocyte depleted Hodgkin lymphoma (C81.3), other Hodgkin lymphoma (C81.7) and unspecified (C81.9).

To report this condition, pick the subcode that matches the documentation: C81.40 (unspecified site), C81.41 (lymph nodes of head, face, and neck), C81.42 (intrathoracic lymph nodes), C81.43 (intra-abdominal lymph nodes), C81.44 (lymph nodes of axilla and upper limb), C81.45 (lymph nodes of inguinal region and lower limb), C81.46 (intrapelvic lymph nodes), C81.47 (spleen) and 3 more.

Don't report C81.4 together with the conditions in its Excludes1 note: nodular lymphocyte predominant Hodgkin lymphoma (C81.0-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised).
