Code Description

ICD-10 M87.361 is a billable code used to indicate a diagnosis of other secondary osteonecrosis, right tibia.

Key Diagnostic Point:

M87.361 refers to other secondary osteonecrosis affecting the right tibia, a condition characterized by the death of bone tissue due to a lack of blood supply. This can occur as a result of various factors, including trauma, prolonged use of corticosteroids, excessive alcohol consumption, or certain medical conditions such as sickle cell disease or systemic lupus erythematosus. In the case of the right tibia, the osteonecrosis may lead to significant pain, swelling, and limited mobility, often mimicking symptoms of osteomyelitis or other bone infections. Diagnosis typically involves imaging studies such as MRI or X-rays, which can reveal changes in bone density and structure. Treatment options may include conservative management with pain relief and physical therapy, or surgical interventions such as core decompression or bone grafting, depending on the severity and progression of the disease. Accurate coding is essential for proper treatment reimbursement and tracking of patient outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between primary and secondary osteonecrosis
  • Identifying the specific location of osteonecrosis (right tibia)
  • Understanding the underlying causes contributing to the condition
  • Navigating the nuances of related codes for osteomyelitis and other bone conditions

Audit Risk Factors

  • Inadequate documentation of the underlying cause of osteonecrosis
  • Failure to specify the affected site accurately
  • Misclassification of osteonecrosis as osteomyelitis
  • Lack of supporting imaging studies in the medical record

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

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

Common Clinical Scenarios

Patients presenting with pain in the right tibia, history of corticosteroid use, or previous trauma.

Billing Considerations

Orthopedic surgeons must document the extent of bone damage and any surgical interventions performed.

Rheumatology

Documentation Requirements

Comprehensive assessment of underlying systemic conditions, laboratory results, and treatment responses.

Common Clinical Scenarios

Patients with autoimmune disorders presenting with joint pain and potential secondary osteonecrosis.

Billing Considerations

Rheumatologists should document the relationship between systemic disease and osteonecrosis.
