Code Description

ICD-10 M87.246 is a billable code used to indicate a diagnosis of osteonecrosis due to previous trauma, unspecified 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 M87.246, the osteonecrosis is specifically attributed to previous trauma affecting the fingers, although the exact finger(s) involved are unspecified. This condition can arise from various types of trauma, including fractures, dislocations, or severe contusions that compromise the vascular supply to the bone. The lack of blood flow leads to bone cell death, which can result in pain, decreased mobility, and potential joint dysfunction. Clinically, patients may present with localized pain in the affected finger(s), swelling, and reduced range of motion. 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 or arthritis. Treatment options may include conservative management with pain relief and physical therapy, or surgical interventions such as core decompression or joint replacement in severe cases. 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

  • Differentiating between osteonecrosis and other bone conditions such as osteomyelitis or arthritis.
  • Determining the specific finger(s) affected when unspecified.
  • Understanding the implications of previous trauma in the coding process.
  • Navigating the documentation requirements for trauma-related conditions.

Audit Risk Factors

  • Inadequate documentation of the trauma history.
  • Failure to specify the affected finger(s) when possible.
  • Misclassification of osteonecrosis as osteomyelitis.
  • Lack of imaging studies to support the diagnosis.

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed documentation of the trauma history, imaging results, and treatment plan.

Common Clinical Scenarios

Patients presenting with pain in the fingers following a fracture or dislocation.

Billing Considerations

Ensure that the documentation clearly states the relationship between the trauma and the development of osteonecrosis.

Radiology

Documentation Requirements

Clear imaging reports indicating the presence of osteonecrosis and ruling out other conditions.

Common Clinical Scenarios

Imaging studies performed on patients with a history of finger trauma.

Billing Considerations

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

Coding Guidelines

Inclusion Criteria

Use M87.246 When
  • According to ICD
  • 10 coding guidelines, M87
  • 246 should be used when the osteonecrosis is directly linked to previous trauma and the specific finger(s) are not identified
  • Coders should ensure that the documentation supports the diagnosis and that all relevant details are captured

Exclusion Criteria

Do NOT use M87.246 When
No specific exclusions found.

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 patient records and reimbursement processes. M87.246 provides a clear framework for coding trauma-related osteonecrosis, which was less detailed in ICD-9.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of conditions like osteonecrosis, improving the accuracy of patient records and reimbursement processes. M87.246 provides a clear framework for coding trauma-related osteonecrosis, which was less detailed in ICD-9.

Reimbursement & Billing Impact

reimbursement processes. M87.246 provides a clear framework for coding trauma-related osteonecrosis, which was less detailed in ICD-9.

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. Accurate diagnosis is crucial for appropriate coding and treatment.
