About C83.1
C83.1 is the ICD-10-CM diagnosis code for Mantle cell lymphoma. It belongs to category C83 (non-follicular 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 C83 (non-follicular lymphoma), C83.1 is specifically for Mantle cell lymphoma. Related codes cover small cell B-cell lymphoma (C83.0), diffuse large B-cell lymphoma (C83.3), lymphoblastic (diffuse) lymphoma (C83.5), Burkitt lymphoma (C83.7), other non-follicular lymphoma (C83.8) and non-follicular (diffuse) lymphoma, unspecified (C83.9).
To report this condition, pick the subcode that matches the documentation: C83.10 (unspecified site), C83.11 (lymph nodes of head, face, and neck), C83.12 (intrathoracic lymph nodes), C83.13 (intra-abdominal lymph nodes), C83.14 (lymph nodes of axilla and upper limb), C83.15 (lymph nodes of inguinal region and lower limb), C83.16 (intrapelvic lymph nodes), C83.17 (spleen) and 3 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
