M30-M36: Systemic connective tissue disorders

M36: Systemic disorders of connective tissue in diseases classified elsewhere

Systemic disorders of connective tissue in diseases classified elsewhere (ICD-10 code M36) is a group of health conditions that happen when problems occur with the body's connective tissue which provides structure and support to the body. These can be associated with other diseases such as lupus or rheumatoid arthritis. The disease roots can differ greatly, but common themes are inflammation and a malfunctioning immune system. Symptoms may include joint pain, swelling, skin changes, fatigue, and fevers, but they can vary widely depending on which tissues are affected. Over time, these ailments often worsen and may interfere with physical function and mobility. The disorders can affect various systems in the body, including the musculoskeletal system, skin, blood vessels, eyes, lungs, and heart. As a group, these disorders do not have a single transmission method as their causes can be a mix of genetic, environmental, and hormonal factors.
