Code Description

ICD-10 M87.276 is a billable code used to indicate a diagnosis of osteonecrosis due to previous trauma, unspecified foot.

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 M87.276, the osteonecrosis is specifically attributed to previous trauma, which may include fractures, dislocations, or other injuries that compromise the vascular supply to the bone. The unspecified foot designation indicates that the specific location within the foot is not detailed, which can complicate treatment and management. Clinically, patients may present with pain, swelling, and limited range of motion in the affected foot. Diagnosis typically involves imaging studies such as X-rays or MRI to assess the extent of bone damage and to rule out other conditions such as osteomyelitis, which is an infection of the bone. Treatment options may include conservative management with pain relief and physical therapy, or surgical interventions such as core decompression or joint replacement in more severe cases. 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 trauma history and its impact on bone health
  • Differentiation from other conditions like osteomyelitis
  • Need for precise documentation of previous trauma
  • Potential for multiple affected sites in the foot

Audit Risk Factors

  • Insufficient documentation of trauma history
  • Inadequate imaging reports to support diagnosis
  • Failure to differentiate from osteomyelitis
  • Lack of follow-up documentation on treatment outcomes

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed history of trauma, imaging results, and treatment plans.

Common Clinical Scenarios

Patients presenting with foot pain post-trauma, requiring surgical intervention.

Billing Considerations

Documentation must clearly link the trauma to the osteonecrosis to support the diagnosis.

Podiatry

Documentation Requirements

Foot examination findings, patient history, and any conservative management undertaken.

Common Clinical Scenarios

Patients with chronic foot pain and a history of trauma, often requiring conservative treatment.

Billing Considerations

Focus on the specific foot anatomy and potential complications related to osteonecrosis.

Inclusion Criteria

Use M87.276 When
  • According to ICD
  • 10 guidelines, M87
  • 276 should be used when osteonecrosis is confirmed to be due to previous trauma and the specific foot is not identified
  • Coders must ensure that the documentation supports the diagnosis and that the trauma history is clearly outlined

Exclusion Criteria

Arthrocentesis, aspiration and/or injection into a major joint or bursa

Clinical Scenario

Used when a patient with osteonecrosis requires joint aspiration for pain relief.

Documentation Requirements

Document the indication for the procedure and the findings during aspiration.

Specialty Considerations

Orthopedic specialists may perform this procedure to alleviate symptoms.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding osteonecrosis, enabling better tracking of treatment outcomes and resource allocation. M87.276 provides a clear framework for identifying cases related to trauma, which can improve patient management.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding osteonecrosis, enabling better tracking of treatment outcomes and resource allocation. M87.276 provides a clear framework for identifying cases related to trauma, which can improve patient management.
