Other specified disorders of synovium, right shoulder

This code signifies a non-specific, yet identified, disorder affecting the synovial membrane or fluid within the right shoulder joint. It encompasses conditions like synovitis, synovial cysts, or other inflammatory/degenerative processes of the synovium that are not classified elsewhere.

Apply this code when documentation specifies a disorder of the right shoulder synovium that doesn't have a more precise ICD-10-CM code. This includes conditions such as villonodular synovitis, synovial hypertrophy, or other specified synovial pathology of the right shoulder. Ensure the medical record clearly indicates the right shoulder as the affected site.

• Always confirm the specific shoulder (right vs. left) is documented to avoid laterality errors.
• Avoid using this code if a more specific diagnosis for the synovial disorder (e.g., M65.811 for other synovitis and tenosynovitis, right shoulder) is available.
• Review operative reports or imaging findings for definitive diagnoses of synovial conditions.
