M21.831
ICD-10-CMThis code signifies an acquired, non-congenital structural abnormality of the right forearm that is not classified under more specific deformity codes. It encompasses various conditions such as malunion or nonunion of fractures, post-traumatic angulation, or other structural changes impacting the normal anatomy and function of the right forearm.
Use this code when documentation specifies an acquired deformity of the right forearm that doesn't fit a more precise ICD-10-CM code. This often applies to conditions like chronic post-fracture deformities, contractures, or other structural changes resulting from injury or disease. Documentation should clearly state "acquired deformity" and specify the right forearm.
