M46.8: Other specified inflammatory spondylopathies

"Other specified inflammatory spondylopathies" refers to a condition where inflammation affects the vertebrae, or the bones of the spine. This type of illness may be caused by a variety of factors, from infections to autoimmune disorders. This condition is typically associated with back pain that is particularly noticeable in the morning or after periods of inactivity. Other symptoms may include stiffness that improves with activity, as well as fatigue, loss of appetite, and overall discomfort. Over time, if the inflammation is not managed, it could potentially lead to the development of new bone in the spine, causing the vertebrae to fuse together and limit spine flexibility. Depending on the specific underlying cause, other body systems such as the eyes, skin, or gastrointestinal tract may also be affected.
