C88Malignant immunoproliferative diseases and certain other B-cell lymphomas

C88 is the ICD-10-CM diagnosis code for malignant immunoproliferative diseases and certain other B-cell lymphomas. 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: C88.0 (macroglobulinemia), C88.2 (disease), C88.3 (disease), C88.4 ([MALT-lymphoma]), C88.8 (diseases) and C88.9 (unspecified).

Don't report C88 together with the conditions in its Excludes1 note: B-cell lymphoma, unspecified (C85.1-) and personal history of other malignant neoplasms of lymphoid, hematopoietic and related tissues (Z85.79).

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