Code Description

ICD-10 M87.245 is a billable code used to indicate a diagnosis of osteonecrosis due to previous trauma, left finger(s).

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 M87.245, the osteonecrosis is specifically attributed to previous trauma affecting the left finger(s). This condition can arise after fractures, dislocations, or other injuries that compromise the blood supply to the bone. The affected area may experience pain, swelling, and limited range of motion. Over time, if not treated, the bone may collapse, leading to joint dysfunction and chronic pain. Diagnosis typically involves imaging studies such as X-rays or MRI to assess the extent of bone damage. Treatment options may include conservative measures like rest and pain management, or surgical interventions such as core decompression or joint replacement, depending on the severity of the condition. Understanding the underlying cause of osteonecrosis is crucial for effective management and prevention of further complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of the relationship between trauma and osteonecrosis.
  • Differentiation from other types of osteonecrosis.
  • Documentation must specify the location (left finger(s)).
  • Potential for co-morbid conditions affecting coding.

Audit Risk Factors

  • Insufficient documentation linking trauma to osteonecrosis.
  • Inaccurate anatomical localization.
  • Failure to document prior treatments or interventions.
  • Lack of imaging studies to support diagnosis.

  • 10 guidelines, M87
  • 245 should be used when there is clear documentation of osteonecrosis due to previous trauma specifically affecting the left finger(s)
  • It is important to ensure that the trauma is well
  • documented and that the osteonecrosis is confirmed through imaging

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of conditions like osteonecrosis, improving the accuracy of diagnoses and treatment tracking. M87.245 provides a clear link between trauma and the resulting condition, which is essential for appropriate management and reimbursement.

ICD-9 vs ICD-10

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. They require different treatment approaches and coding.
