Code Description

ICD-10 M87.344 is a billable code used to indicate a diagnosis of other secondary osteonecrosis, right finger(s).

Key Diagnostic Point:

M87.344 refers to a specific type of osteonecrosis that occurs in the right finger(s) as a result of secondary factors, such as trauma, corticosteroid use, or underlying medical conditions like sickle cell disease or systemic lupus erythematosus. Osteonecrosis, also known as avascular necrosis, is characterized by the death of bone tissue due to a lack of blood supply. In the case of secondary osteonecrosis, the condition is not idiopathic but rather a consequence of other medical issues or external factors. Patients may present with pain, swelling, and limited range of motion in the affected finger(s). Diagnosis typically involves imaging studies such as X-rays or MRI to assess the extent of bone damage. Treatment options may include conservative management with pain relief, physical therapy, or surgical interventions such as core decompression or joint replacement, depending on the severity of the condition. Understanding the underlying cause of the osteonecrosis is crucial for effective management and prevention of further complications.

  • Differentiation from primary osteonecrosis
  • Need for detailed documentation of underlying conditions
  • Potential for multiple contributing factors
  • Variability in treatment approaches

Audit Risk Factors

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

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed history of the patient's condition, imaging results, and treatment plans.

Common Clinical Scenarios

Patients with a history of corticosteroid use presenting with finger pain.

Billing Considerations

Ensure accurate documentation of the specific finger(s) affected and any underlying conditions contributing to osteonecrosis.

Rheumatology

Documentation Requirements

Comprehensive assessment of systemic conditions that may lead to osteonecrosis.

Common Clinical Scenarios

Patients with autoimmune diseases presenting with joint pain and swelling.

Billing Considerations

Document the relationship between systemic disease and osteonecrosis to support coding.

Inclusion Criteria

Use M87.344 When
  • According to ICD
  • 10 coding guidelines, M87
  • 344 should be used when the osteonecrosis is confirmed to be secondary to other conditions
  • Coders must ensure that the documentation supports the diagnosis and that the specific finger(s) affected are clearly indicated

Exclusion Criteria

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 secondary causes and improving patient care through targeted treatment plans.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding osteonecrosis, enabling better tracking of secondary causes and improving patient care through targeted treatment plans.

Reimbursement & Billing Impact
