M90.1: Periostitis in other infectious diseases classified elsewhere

Periostitis is a medical condition that involves inflammation of the periosteum, a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints. This inflammation can cause a variety of symptoms, most notably, pain, and tenderness in the affected area. Periostitis in other infectious diseases classified elsewhere, as its name suggests, commonly originates from another infectious disease elsewhere in the body. This means that the inflammation is caused by an infection that comes from a different location in your body. Significantly, it implies the risk of systemic infection, where an infection starts in one part of the body but spreads through the bloodstream to others. Typical disease progression can lead to the formation of a painful bone deformity if not treated. As the condition involves the skeletal system, it primarily affects the function and health of your bones. However, as a secondary condition, it can also interfere with the workings of any system in your body that was involved in the original infection.
