M88.8: Paget disease of other bones

Paget's disease of other bones, coded as M88.8 in the ICD-10, is a chronic condition that affects the normal cycle of bone growth. Typically, our bones continuously renew and reshape themselves, a process called remodeling. However, in Paget's disease, this process becomes unusually accelerated, leading to new bone that's soft, weak, and abnormally shaped. This condition primarily affects the older adult population. While the exact cause is unknown, it's suggested that both genetic factors and viral infections may play a role. Symptoms can vary greatly, from no signs at all to significant bone pain, fractures, and deformities. Other common signs can include warmth in the affected area and reduced height due to spinal involvement. The progression of Paget's disease can also lead to complications affecting other body systems, such as the heart and nervous system.
