M67.821
ICD-10-CMThis code signifies an unspecified, non-inflammatory condition affecting the synovial membrane or related structures within the right elbow joint, not classified elsewhere. It covers various rare or atypical synovial disorders that manifest in the elbow but don't fit into more specific diagnostic categories.
Apply this code when documentation clearly indicates a disorder of the synovium in the right elbow that is not arthritis, infection, or a specific named condition like synovitis or tenosynovitis. This code is appropriate for conditions such as synovial cysts, villonodular synovitis, or other rare synovial abnormalities of the right elbow when a more specific code is unavailable.
