M87.8: Other osteonecrosis
Osteonecrosis goes by the term bone death. It is a condition where an insufficient supply of blood causes the bone to die and collapse. The disease coded by ICD-10 as M87.8 is known specifically as “other osteonecrosis,” indicating it represents a subtype of osteonecrosis not included in the standard types characterized or categorized by site or by cause. Symptoms can include joint pain, limited range of motion, and in progressed cases, visible signs of joint breakdown, such as limping. Over time, other osteonecrosis may lead to severe damage or the destruction of a joint, usually the hip, knee, or shoulder. This condition can be caused by numerous factors, including trauma, the use of high-dose steroid medications, and excessive alcohol consumption, which all can affect the blood supply to bone, ultimately leading to the bone tissue's death.
