M81.8: Other osteoporosis

Osteoporosis classified under the ICD-10 code M81.8 is a bone disorder where the bones become fragile and more prone to fractures. It's termed as "Other osteoporosis" as it includes instances of osteoporosis that don't fall into the standard categories. This could mean that the osteoporosis is caused by certain conditions or treatments that are not typically associated with bone loss. It is usually unnoticed until a bone breaks or fractures, but some people may notice symptoms like back pain or a decrease in height. As the disease progresses, the bones lose more minerals and mass, becoming so porous that even minor stresses can cause fractures or other injuries. It can affect any bones in the body, but the hips, spine, and wrists are often most affected.
