M21.851
ICD-10-CMThis code signifies an acquired structural abnormality or malformation of the right thigh that is not congenital and does not fit into more specific categories of acquired deformities. It encompasses a range of non-traumatic, non-infectious, or non-neoplastic changes to the bone, muscle, or soft tissues of the right thigh that result in an altered shape or function.
Apply this code when documentation specifies an acquired deformity of the right thigh that is not otherwise classified, such as a post-surgical contour irregularity, a chronic soft tissue contracture, or a localized muscle atrophy not due to a specific neurological condition. Supporting documentation should clearly state "acquired deformity of right thigh" and rule out more specific diagnoses.
