M21: Other acquired deformities of limbs

M21.8: Other specified acquired deformities of limbs

The ICD-10 code M21.8 refers to Other specified acquired deformities of limbs. This medical condition, as the name suggests, is characterized by physical deformities of the limbs (arms or legs) that are not congenital, meaning they are not present at birth but arise later in life. These deformities can be the result of a wide range of causes such as trauma, disease, or prolonged abnormal positioning. The patient may experience visible changes in the shape or structure of the affected limb, which can impair normal movement and function. The condition may also cause discomfort or pain, depending on the severity and location of the deformity. As this is a broad category, the specific symptoms and progression can vary significantly from case to case.
