M49.3: Spondylopathy in other infectious and parasitic diseases classified elsewhere

Spondylopathy in other infectious and parasitic diseases classified elsewhere (M49.3) refers to the degenerative diseases of the spine that can occur secondary to certain infectious or parasitic diseases. These conditions cause significant changes to the structure of the spine as a result of the body's reaction to a harmful disease-causing agent, such as a bacterium, virus, or parasite. Common symptoms of this condition can include chronic pain, stiffness, and limited mobility, especially in the back or neck. The progression of the disease can lead to structural deformities that may affect balance and coordination in severe cases. The nature, severity, and progression of symptoms could largely depend on the underlying infectious or parasitic disease, and its interaction with the patient's immune system and overall health. Spinal tissues, nerves, and joints are the primary systems affected by these conditions.
