M25: Other joint disorders, not elsewhere classified

M25.8: Other specified joint disorders

"Other specified joint disorders" refers to specific conditions affecting the body's joints that do not fall under the other defined categories. This group of disorders generally involve discomfort, pain, inflammation or a decrease in function of the joints. These may occur as a result of injury, general wear and tear, or because of an underlying disease such as osteoarthritis or rheumatoid arthritis. The symptoms can vary widely based on the specific disorder, but commonly include stiffness, swelling and joint pain. The severity of symptoms can fluctuate, often worsening with physical activity or in cold weather. Any joint in the body can be affected by these disorders, from the large joints like the hip, knee, and shoulder, to small ones like the fingers and toes. While these conditions frequently affect older adults, they can occur at any age.
