Within D47 (other neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue), D47.1 is specifically for chronic myeloproliferative disease. Related codes cover mast cell neoplasms of uncertain behavior (D47.0), monoclonal gammopathy (D47.2), essential (hemorrhagic) thrombocythemia (D47.3), Osteomyelofibrosis (D47.4), neoplasm of uncertain behavior of lymphoid, hematopoietic and related tissue, unspecified (D47.9) and other specified neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue (D47.Z).
Don't report D47.1 together with the conditions in its Excludes1 note: atypical chronic myeloid leukemia BCR/ABL-negative (C92.2-), chronic myeloid leukemia BCR/ABL-positive (C92.1-), myelofibrosis NOS (D75.81), myelophthisic anemia (D61.82) and 2 more.
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
