Code Description

ICD-10 M87.28 is a billable code used to indicate a diagnosis of osteonecrosis due to previous trauma, other site.

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 M87.28, the osteonecrosis is specifically attributed to previous trauma, which can include fractures, dislocations, or other injuries that compromise the vascular supply to the bone. This condition can occur in various sites throughout the body, including the femoral head, knee, and shoulder. Symptoms often include pain, limited range of motion, and joint dysfunction. Diagnosis typically involves imaging studies such as X-rays or MRI to assess the extent of bone damage. Treatment options may include conservative management, such as physical therapy and pain relief, or surgical interventions like core decompression or joint replacement, depending on the severity and location of the osteonecrosis. Understanding the underlying cause, particularly the history of trauma, is crucial for effective management and coding.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires detailed documentation of prior trauma history
  • Differentiation from other types of osteonecrosis
  • Potential for multiple sites of involvement
  • Need for imaging results to confirm diagnosis

Audit Risk Factors

  • Inadequate documentation of trauma history
  • Failure to specify the site of osteonecrosis
  • Lack of imaging studies in the medical record
  • Misclassification of osteonecrosis type

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed history of trauma, imaging results, treatment plans, and follow-up notes.

Common Clinical Scenarios

Patients presenting with joint pain following a fracture or dislocation, requiring evaluation for osteonecrosis.

Billing Considerations

Ensure clear documentation of the trauma event and its relation to the osteonecrosis for accurate coding.

Radiology

Documentation Requirements

Imaging reports that clearly indicate the presence of osteonecrosis and any associated findings.

Common Clinical Scenarios

Imaging studies performed to evaluate joint pain in patients with a history of trauma.

Billing Considerations

Radiologists should provide detailed descriptions of findings to support the diagnosis and coding.

Coding Guidelines

Inclusion Criteria

Use M87.28 When
  • According to ICD
  • 10 coding guidelines, M87
  • 28 should be used when osteonecrosis is specifically due to previous trauma and the site is not specified elsewhere
  • Coders must ensure that the documentation supports the diagnosis and that the trauma history is clearly outlined

Exclusion Criteria

Do NOT use M87.28 When
No specific exclusions found.

Documentation Requirements

Document the indication for the procedure and any imaging findings.

Specialty Considerations

Orthopedic specialists should ensure that the procedure is linked to the diagnosis of osteonecrosis.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the accuracy of data collection and reimbursement. M87.28 provides a clear distinction for osteonecrosis due to trauma, which was less defined in ICD-9.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the accuracy of data collection and reimbursement. M87.28 provides a clear distinction for osteonecrosis due to trauma, which was less defined in ICD-9.

Reimbursement & Billing Impact

reimbursement. M87.28 provides a clear distinction for osteonecrosis due to trauma, which was less defined in ICD-9.

Frequently Asked Questions

What is the difference between M87.28 and M87.21?

M87.28 is used for osteonecrosis due to previous trauma at an unspecified site, while M87.21 is specific to the right femur. The choice of code depends on the documented site of the osteonecrosis.
