Code Description

ICD-10 M87.061 is a billable code used to indicate a diagnosis of idiopathic aseptic necrosis of right tibia.

Key Diagnostic Point:

Idiopathic aseptic necrosis of the right tibia is a condition characterized by the death of bone tissue due to a lack of blood supply, without the presence of infection. This condition is often seen in younger adults and can be associated with various risk factors, including corticosteroid use, alcohol consumption, and certain medical conditions such as sickle cell disease. The right tibia is specifically affected, leading to pain, swelling, and potential functional impairment. Diagnosis typically involves imaging studies such as X-rays or MRI, which can reveal changes in bone density and structure. Treatment options may include conservative management with pain relief, physical therapy, or surgical interventions such as core decompression or bone grafting, depending on the severity of the necrosis. The idiopathic nature of this condition means that the exact cause is often unknown, complicating treatment and management strategies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Idiopathic nature complicates diagnosis and treatment planning.
  • Differentiation from other forms of osteonecrosis is required.
  • Potential for co-morbid conditions affecting treatment.
  • Documentation must clearly indicate the absence of infection.

Audit Risk Factors

  • Inadequate documentation of the idiopathic nature.
  • Failure to document imaging results supporting diagnosis.
  • Misclassification with osteomyelitis codes.
  • Lack of detail on treatment plans and patient outcomes.
