M67.8: Other specified disorders of synovium and tendon

The condition classified under ICD-10 code M67.8 pertains to certain specific disorders that affect the synovium and tendons. The synovium is a soft, thin tissue that lines the parts of your joints that don't involve the bone, whereas tendons are flexible connective tissues that link your muscles to your bones. When these components of your musculoskeletal system encounter certain disorders, you may experience discomfort, pain, swelling, and potential difficulties in performing regular movements. Though the exact cause of such conditions can vary, they often arise due to repetitive stress or injury. In some cases, you could notice a gradual onset of symptoms, whereas in other situations these conditions might present themselves quite abruptly. If left unchecked, these disorders can progressively worsen and impact your body's flexibility and mobility.
