**Note 2:** Codes 0, 2, and 4 are not applicable for this chapter.
**Note 3:** Plasma cell myeloma/multiple myeloma (9732) is a widely disseminated plasma cell neoplasm, characterized by a single clone of plasma cells derived from B cells that grows in the bone marrow. It is always coded to 7 for systemic involvement.
**Note 4:** Lymphoplasmacytic lymphoma (9671) and Waldenstrom Macroglobulinemia (9761) are now collected with the plasma cell disorders. These are systemic diseases and should always be coded 7.
