Code Description

ICD-10 M87.188 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs, other site.

Key Diagnostic Point:

Osteonecrosis due to drugs, classified under ICD-10 code M87.188, refers to the death of bone tissue resulting from a lack of blood supply, specifically induced by pharmacological agents. This condition can occur in various sites of the body, most commonly in the femoral head, but can also affect other bones. The pathophysiology involves the disruption of blood flow to the bone, which can be caused by long-term use of certain medications, such as corticosteroids, bisphosphonates, and chemotherapy agents. Patients may present with pain, limited range of motion, and functional impairment. Diagnosis typically involves imaging studies such as MRI or X-rays, which can reveal changes in bone density and structure. Treatment options may include conservative management, such as pain control and physical therapy, or surgical interventions like core decompression or joint replacement, depending on the severity of the condition. Understanding the implications of drug-induced osteonecrosis is crucial for healthcare providers, as early recognition and intervention can significantly improve patient outcomes.

  • Differentiation from other types of osteonecrosis
  • Potential for multiple sites of involvement

Audit Risk Factors

  • Inadequate documentation of drug history
  • Failure to specify the site of osteonecrosis
  • Lack of imaging studies to support diagnosis
  • Misclassification of osteonecrosis as osteomyelitis
