Amyloidosis
Codes E85.81, Light chain (AL) amyloidosis, E85.82, Wild-type transthyretin-related (ATTR) amyloidosis, and E85.89, Other amyloidosis, have been created to employ the most recent terminology and classification for amyloidosis. Amyloidosis involves deposits of proteins that have become misfolded, going from a normal soluble state to an insoluble structure. These proteins are produced by the bone marrow and may be localized, with amyloid protein deposited in the organ or tissue where the protein was produced; or systemic, where fibrils of amyloid protein are carried through the plasma of the blood and deposited at one or more sites distant...
