How to code Monoclonal Gammopathy (MGUS)
D47.2 (monoclonal gammopathy) is the code for MGUS, including IgG, IgA, and IgM MGUS. It is a neoplasm of uncertain behavior, so it is not reported as multiple myeloma or as a history of cancer.
Progression to multiple myeloma is coded from C90.0-, using C90.00 when not in remission and C90.01 when in remission. Waldenstrom macroglobulinemia is coded from C88.0-. Polyclonal hypergammaglobulinemia is D89.2, not D47.2.
