Help me code for diagnosis year :
1. Waldenstrom Macroglobulinemia (WM) (9761/3) is a subset of LPL. WM is caused by increased lymphocytes which causes an increase in IgM. See the abstractor notes for WM for more information.
2. Gamma heavy chain disease (9762/3) is a variant of LPL. Gamma heavy chain disease is caused by increased plasma cells which results in an increase of IgG. See the abstractor notes for Gamma heavy chain disease for more information.
All three diseases are diagnosed by an increased number of immunoglobulins.
