Code Description

ICD-10 M87.342 is a billable code used to indicate a diagnosis of other secondary osteonecrosis, left hand.

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 M87.342, the osteonecrosis is secondary, meaning it is a result of another underlying condition or factor, such as trauma, corticosteroid use, or excessive alcohol consumption. The left hand is specifically affected, which can lead to significant pain, limited mobility, and potential complications such as fractures or joint degeneration. Patients may present with symptoms including localized pain, swelling, and decreased range of motion in the affected area. 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 such as core decompression or joint replacement, 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

  • Differentiating between primary and secondary osteonecrosis.
  • Identifying the underlying causes contributing to the condition.
  • Accurate documentation of the affected site (left hand).
  • Understanding the implications of associated conditions (e.g., diabetes, corticosteroid use).

Audit Risk Factors

  • Inadequate documentation of the underlying cause of osteonecrosis.
  • Failure to specify the affected site accurately.
  • Misclassification of osteonecrosis as osteomyelitis.
  • Lack of imaging documentation to support the diagnosis.

Frequently Asked Questions

What is the difference between osteonecrosis and osteomyelitis?

Osteonecrosis is the death of bone tissue due to lack of blood supply, while osteomyelitis is an infection of the bone. Accurate diagnosis is crucial for appropriate treatment.
