Code Description

ICD-10 M48.48 is a billable code used to indicate a diagnosis of fatigue fracture of vertebra, sacral and sacrococcygeal region.

Key Diagnostic Point:

Fatigue fractures of the vertebrae, particularly in the sacral and sacrococcygeal regions, are often the result of repetitive stress or overuse, leading to microtrauma that exceeds the bone's ability to repair itself. These fractures are commonly seen in individuals with underlying conditions such as spondylopathies, ankylosing spondylitis, or spinal stenosis, which can predispose the vertebrae to weakness and increased susceptibility to fractures. Patients may present with localized pain, tenderness, and reduced mobility, often exacerbated by activities that place stress on the spine. Diagnosis typically involves imaging studies such as X-rays, MRI, or CT scans to confirm the presence of a fracture and assess any associated spinal deformities or complications. Management may include conservative treatment options such as rest, physical therapy, and pain management, although surgical intervention may be necessary in cases of severe instability or neurological compromise. 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 fatigue fractures and other types of vertebral fractures.
  • Identifying underlying conditions such as ankylosing spondylitis or spinal stenosis.
  • Documenting the specific location and severity of the fracture.
  • Understanding the implications of co-existing conditions on treatment and prognosis.

Audit Risk Factors

  • Inadequate documentation of the fracture type and location.
  • Failure to document underlying conditions that contribute to the fracture.
  • Misclassification of the fracture as acute rather than fatigue-related.
  • Lack of imaging studies to support the diagnosis.

Frequently Asked Questions

What is the difference between a fatigue fracture and an acute fracture?

A fatigue fracture results from repetitive stress over time, while an acute fracture occurs suddenly due to trauma. Accurate documentation is essential to differentiate between the two for coding purposes.
