About D47.Z

D47.Z is the ICD-10-CM diagnosis code for other specified neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue. It belongs to category D47 (other neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue), block D37-D48 (neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within D47, choose D47.Z (Other specified neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue) only when documentation doesn't support a more specific option: mast cell neoplasms of uncertain behavior (D47.0), chronic myeloproliferative disease (D47.1), monoclonal gammopathy (D47.2), essential (hemorrhagic) thrombocythemia (D47.3), Osteomyelofibrosis (D47.4) and neoplasm of uncertain behavior of lymphoid, hematopoietic and related tissue, unspecified (D47.9).

To report this condition, pick the subcode that matches the documentation: D47.Z1 ((PTLD)), D47.Z2 (disease) and D47.Z9 (tissue).

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