Code Description

ICD-10 M87.277 is a billable code used to indicate a diagnosis of osteonecrosis due to previous trauma, right toe(s).

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 M87.277, the osteonecrosis is specifically attributed to previous trauma affecting the right toe(s). This condition can arise following fractures, dislocations, or other injuries that compromise the vascular supply to the bone. The affected area may experience pain, swelling, and limited mobility, which can lead to further complications such as osteomyelitis if infection occurs. The right toe(s) may show signs of bone collapse or deformity on imaging studies. Diagnosis typically involves a combination of clinical evaluation, imaging (such as MRI or X-rays), and sometimes biopsy to rule out other conditions. Treatment options may include conservative management with pain relief and physical therapy, or surgical interventions such as core decompression or joint replacement in severe cases. Understanding the underlying cause of osteonecrosis is crucial for effective management and prevention of further complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires accurate documentation of previous trauma.
  • Differentiation from other types of osteonecrosis.
  • Potential for co-existing conditions like osteomyelitis.
  • Need for precise anatomical localization (right toe(s)).

Audit Risk Factors

  • Inadequate documentation of trauma history.
  • Failure to specify the affected toe(s).
  • Misdiagnosis or lack of differentiation from osteomyelitis.
  • Insufficient imaging reports to support diagnosis.
