About C85
C85 is the ICD-10-CM diagnosis code for other specified and unspecified types of non-Hodgkin 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 4 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: C85.1 (lymphoma), C85.2 (lymphoma), C85.8 (lymphoma) and C85.9 (unspecified).
Don't report C85 together with the conditions in its Excludes1 note: other specified types of T/NK-cell lymphoma (C86.-) and 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.
