Code Description

ICD-10 M87.131 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs of right radius.

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 M87.131, the osteonecrosis is specifically attributed to the use of certain drugs, which can disrupt blood flow to the bone. The right radius, one of the two long bones in the forearm, is affected in this instance. Commonly implicated drugs include corticosteroids and bisphosphonates, which are often prescribed for conditions such as rheumatoid arthritis, lupus, or osteoporosis. Patients may present with pain, swelling, and limited range of motion in the affected arm. Diagnosis typically involves imaging studies such as X-rays or MRI to assess bone integrity and blood flow. Treatment options may include medication adjustments, physical therapy, or surgical interventions like core decompression or joint replacement, depending on the severity of the condition. Understanding the underlying causes and appropriate management strategies is crucial for optimizing patient outcomes and preventing further complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of drug-induced conditions and their effects on bone health.
  • Differentiating between osteonecrosis and other bone pathologies.
  • Need for precise documentation of drug history and dosage.
  • Understanding the implications of osteonecrosis on orthopedic procedures.

Audit Risk Factors

  • Inadequate documentation of drug history.
  • Failure to specify the affected bone accurately.
  • Misclassification of osteonecrosis as osteomyelitis.
  • Lack of imaging studies to support diagnosis.
