M21.121
ICD-10-CMThis code signifies an inward angulation of the right elbow joint, where the forearm deviates medially relative to the upper arm. This deformity is not congenital and is not classified under other specific conditions. It indicates a structural abnormality affecting the alignment of the bones in the right elbow.
Use this code when documentation clearly states a varus deformity of the right elbow that is acquired or of unknown origin, and not a result of a congenital condition, trauma (unless specified as a late effect), or another specific disease process. Supporting documentation should include physical exam findings describing the angulation and potentially imaging reports confirming the deformity.
