DETERMINATION OF SUBSEQUENT PRIMARIES OFLYMPHATIC (NODAL AND EXTRANODAL) AND HEMATOPOIETIC DISEASESFirst Primary Presumably a Second Presumably NOT aSubsequent Primary Subsequent Primary(only One Primary)Lymphocytic leukemia Hodgkin's disease Non-Hodgkin's(9820-9827) (9650-9667) lymphoma 2 (9592-9595,9670-9687, 9690-9698,Malignant histiocytosis or 9702-9714)Letterer-Siwe's disease(9720, 9722) Malignant lymphoma,NOS 2 (9590-9591)Plasmacytoma or multiplemyeloma (9731, 9732) Mycosis fungoides orSezary's disease 3 (9700,Mast cell tumor (9740, 9701)9741)True histiocytic lymphomaWaldenstrom's (9723)macroglobulinemia (9761)Leukemia, NOS (9800)Non-lymphocyticleukemias 1 (9840-9842, Acute leukemia, NOS9860-9910) (9801)Myeloid sarcoma 1 (9930) Chronic leukemia, NOS(9803)Acute panmyelosis 1(9931) Lymphocytic leukemia 3(9820-9827)Acute myelofibrosis 1(9932)1If any of these diagnoses are made within 4 months of lymphocytic leukemia, NOS (9820) oracute lymphocytic leukemia (982I), one of the two diagnoses probably is wrong. The case shouldbe reviewed.2If the diagnosis includes "can't rule out leukemia" or "consistent with chronic lymphocyticleukemia," and a bone marrow or peripheral blood study within two months confirms the chroniclymphocytic leukemia diagnosis; then code only to chronic lymphocytic leukemia (9823). If notconfirmed as chronic lymphocytic leukemia, then code as the lymphoma.3Note: Lymphocytic leukemia, NOS (9820) should be upgraded to a more specific diagnosisthat is not considered a second primary.461
