About C83

C83 is the ICD-10-CM diagnosis code for non-follicular lymphoma. It belongs to 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: C83.0 (lymphoma), C83.1 (lymphoma), C83.3 (lymphoma), C83.5 (lymphoma), C83.7 (lymphoma), C83.8 (lymphoma) and C83.9 (unspecified).

Don't report C83 together with the conditions in its Excludes1 note: personal history of non-Hodgkin lymphoma (Z85.72).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
