Code Description

ICD-10 M87.01 is a billable code used to indicate a diagnosis of idiopathic aseptic necrosis of shoulder.

Key Diagnostic Point:

Idiopathic aseptic necrosis of the shoulder, also known as osteonecrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. This condition can occur in various joints, but when it affects the shoulder, it can lead to significant pain, limited range of motion, and functional impairment. The etiology of idiopathic aseptic necrosis remains unclear, but it is often associated with risk factors such as corticosteroid use, alcohol consumption, and certain medical conditions like sickle cell disease or lupus. Patients typically present with shoulder pain that may be exacerbated by activity and relieved by rest. Diagnosis is often confirmed through imaging studies, including MRI, which can reveal changes in bone marrow and the presence of subchondral fractures. Treatment options vary based on the severity of the condition and may include conservative management with physical therapy and pain control, or surgical interventions such as core decompression or joint replacement in advanced cases. Early diagnosis and intervention are crucial to prevent further joint deterioration and maintain shoulder function.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes that can complicate diagnosis.
  • Need for precise imaging documentation to support diagnosis.
  • Differentiation from other types of shoulder pain or osteonecrosis.
  • Potential for co-morbid conditions that may affect treatment and coding.

Audit Risk Factors

  • Inadequate documentation of imaging studies.
  • Failure to document the idiopathic nature of the condition.
  • Lack of detailed treatment plans in medical records.
  • Misclassification of the condition as traumatic or infectious.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the ability to track and manage this condition. M87.01 provides a clear distinction for idiopathic cases, which aids in research and treatment planning.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the ability to track and manage this condition. M87.01 provides a clear distinction for idiopathic cases, which aids in research and treatment planning.
