Code Description

ICD-10 M87.345 is a billable code used to indicate a diagnosis of other secondary osteonecrosis, left finger(s).

Key Diagnostic Point:

M87.345 refers to a specific type of osteonecrosis affecting the left finger(s) that is secondary to other underlying conditions. Osteonecrosis, also known as avascular necrosis, occurs when blood supply to a bone is disrupted, leading to bone death and potential collapse. In the case of secondary osteonecrosis, this condition may arise from various factors such as trauma, corticosteroid use, excessive alcohol consumption, or underlying diseases like systemic lupus erythematosus or sickle cell disease. The left fingers are particularly susceptible due to their vascular supply and the mechanical stress they endure. Clinically, patients may present with pain, swelling, and limited range of motion in the affected fingers. Diagnosis typically involves imaging studies such as X-rays or MRI to assess bone integrity and blood flow. Treatment options may include conservative management with pain relief, physical therapy, or surgical interventions like core decompression or joint replacement, depending on the severity of the condition. Accurate coding is essential for proper treatment reimbursement and tracking of patient outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation between primary and secondary osteonecrosis
  • Need for detailed patient history to identify underlying causes
  • Variability in clinical presentation and severity
  • Potential for co-existing conditions affecting coding

Audit Risk Factors

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

Frequently Asked Questions

What is the difference between primary and secondary osteonecrosis?

Primary osteonecrosis occurs without an identifiable cause, while secondary osteonecrosis is due to underlying conditions such as trauma, medications, or systemic diseases.
