Code Description

ICD-10 M87.333 is a billable code used to indicate a diagnosis of other secondary osteonecrosis of unspecified 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 M87.333, the osteonecrosis is classified as secondary, meaning it arises from other underlying conditions or factors, such as trauma, corticosteroid use, or certain diseases like lupus or sickle cell disease. The unspecified radius indicates that the specific location of the osteonecrosis within the radius bone is not detailed. Clinically, patients may present with joint pain, limited range of motion, and swelling. Diagnosis typically involves imaging studies such as X-rays or MRI, which can reveal changes in bone density and structure. Treatment options may include conservative management with pain relief and physical therapy, or surgical interventions like core decompression or joint replacement in more severe cases. Understanding the underlying cause of the osteonecrosis is crucial for effective management and prevention of further complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between primary and secondary osteonecrosis
  • Identifying the underlying causes contributing to the condition
  • Unspecified location may lead to ambiguity in documentation
  • Need for comprehensive patient history to support coding

Audit Risk Factors

  • Inadequate documentation of underlying conditions
  • Failure to specify the location of osteonecrosis
  • Lack of imaging studies to support diagnosis
  • Misclassification of primary vs. secondary osteonecrosis
