Code Description

ICD-10 M87.346 is a billable code used to indicate a diagnosis of other secondary osteonecrosis, unspecified finger(s).

Key Diagnostic Point:

M87.346 refers to a condition characterized by the death of bone tissue in the fingers due to a lack of blood supply, which is classified as secondary osteonecrosis. This condition can arise from various underlying factors, including trauma, corticosteroid use, excessive alcohol consumption, or systemic diseases such as lupus or sickle cell disease. The clinical presentation may include 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 identify necrotic areas. Treatment options may vary based on the severity of the condition and can include conservative management, such as pain relief and physical therapy, or surgical interventions like core decompression or joint replacement. Accurate coding is essential for proper reimbursement and to reflect the complexity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes leading to osteonecrosis
  • Need for precise documentation of secondary causes
  • Differentiation from primary osteonecrosis codes
  • Potential for overlapping symptoms with other conditions

Audit Risk Factors

  • Inadequate documentation of secondary causes
  • Failure to specify the affected finger(s)
  • Misclassification of primary vs. secondary osteonecrosis
  • Lack of imaging studies to support diagnosis
