Code Description

ICD-10 M87.222 is a billable code used to indicate a diagnosis of osteonecrosis due to previous trauma, left humerus.

Key Diagnostic Point:

Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. In the case of M87.222, the osteonecrosis is specifically attributed to previous trauma affecting the left humerus. This condition often arises after fractures, dislocations, or other injuries that compromise the blood supply to the bone. The left humerus, being a long bone in the upper arm, is particularly susceptible to such complications following trauma. Symptoms may include pain, limited range of motion, and eventual joint dysfunction. Diagnosis typically involves imaging studies such as X-rays or MRI to assess the extent of bone damage and to rule out other conditions such as osteomyelitis, which is an infection of the bone. Treatment options may vary from conservative management, including physical therapy and pain management, to surgical interventions like core decompression or joint replacement, depending on the severity of the condition. Understanding the underlying cause of osteonecrosis is crucial for effective management and prevention of further complications.
