Medical Intelligence & Overview
Monoclonal gammopathy, classified under ICD-10 code D47.2, is a condition characterized by the presence of an abnormal protein in the blood called monoclonal protein or M-protein. This condition often occurs without causing symptoms and is usually found during blood tests for other health issues. When diagnosed without any associated disease or symptoms, it is referred to as Monoclonal Gammopathy of Undetermined Significance (MGUS). While MGUS itself is generally benign, it requires regular monitoring because, in certain cases, it may progress to more serious blood disorders such as multiple myeloma or lymphoma.
