Code Description

ICD-10 M87.034 is a billable code used to indicate a diagnosis of idiopathic aseptic necrosis of right ulna.

Key Diagnostic Point:

Idiopathic aseptic necrosis of the ulna is a condition characterized by the death of bone tissue due to a lack of blood supply, specifically affecting the right ulna. This condition is termed 'idiopathic' because the exact cause remains unknown, although it may be associated with factors such as trauma, corticosteroid use, or excessive alcohol consumption. The necrosis leads to bone collapse, pain, and functional impairment of the affected limb. Patients may present with localized pain, swelling, and reduced range of motion in the elbow or wrist. Diagnosis typically involves imaging studies such as X-rays or MRI to assess the extent of necrosis and rule out other conditions like osteomyelitis or fractures. Treatment options may include conservative management with pain relief and physical therapy, or surgical interventions such as bone grafting or joint replacement in severe cases. Understanding the nuances of this condition is crucial for accurate coding and appropriate management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between idiopathic and secondary causes of osteonecrosis.
  • Need for precise documentation of symptoms and imaging findings.
  • Potential overlap with other codes related to bone necrosis and infections.
  • Variability in treatment approaches that may affect coding.

Audit Risk Factors

  • Inadequate documentation of the idiopathic nature of the condition.
  • Failure to document imaging studies that support the diagnosis.
  • Misclassification of the condition as osteomyelitis without proper evidence.
  • Lack of clarity in treatment plans that may lead to coding errors.

Specialty Focus

Orthopedics

Documentation Requirements

Detailed clinical notes including history, physical examination findings, imaging results, and treatment plans.

Common Clinical Scenarios

Patients presenting with elbow pain, limited range of motion, or history of trauma.

Billing Considerations

Ensure clear documentation of the idiopathic nature and exclusion of other causes of bone necrosis.

Radiology

Documentation Requirements

Comprehensive imaging reports that detail findings consistent with aseptic necrosis.

Common Clinical Scenarios

Imaging studies performed for patients with suspected bone necrosis.

Billing Considerations

Radiologists should provide clear descriptions of findings to support the diagnosis.

Inclusion Criteria

Use M87.034 When
  • According to ICD
  • 10 coding guidelines, M87
  • 034 should be used when the condition is confirmed as idiopathic and not due to other identifiable causes
  • Documentation must support the diagnosis, including imaging results and clinical findings

Exclusion Criteria
