Code Description

ICD-10 M87.331 is a billable code used to indicate a diagnosis of other secondary osteonecrosis 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 M87.331, the osteonecrosis is secondary, meaning it arises as a complication of another underlying condition or factor, such as corticosteroid use, trauma, or systemic diseases like lupus or sickle cell disease. The right radius, one of the two bones in the forearm, is specifically affected in this diagnosis. Patients may present with pain, limited range of motion, and swelling in the wrist or forearm. Diagnosis typically involves imaging studies such as X-rays or MRI to assess the extent of bone damage. Treatment options may include conservative management with pain relief, physical therapy, or surgical interventions like core decompression or bone grafting, depending on the severity of the condition. Understanding the etiology and management of secondary osteonecrosis is crucial for effective treatment and rehabilitation.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of secondary causes of osteonecrosis.
  • Differentiation from primary osteonecrosis codes.
  • Need for precise documentation of underlying conditions.
  • Potential for multiple comorbidities affecting coding.

Audit Risk Factors

  • Inadequate documentation of underlying conditions.
  • Failure to specify laterality (right vs. left).
  • Misclassification of primary vs. secondary osteonecrosis.
  • Lack of imaging studies to support diagnosis.
