Code Description

ICD-10 M46.2 is a billable code used to indicate a diagnosis of osteomyelitis of vertebra.

Key Diagnostic Point:

Osteomyelitis of the vertebra refers to an infection of the bone within the spinal column, which can lead to significant morbidity if not diagnosed and treated promptly. This condition is often caused by bacterial infections, which may arise from hematogenous spread, direct extension from adjacent soft tissue infections, or post-surgical complications. Patients may present with localized pain, fever, and neurological deficits depending on the extent of the infection and any resultant spinal cord compression. Imaging studies, such as MRI or CT scans, are crucial for diagnosis, revealing bone edema, abscess formation, and other characteristic changes. Treatment typically involves a combination of antibiotics and, in some cases, surgical intervention to debride infected tissue or stabilize the spine. The condition can be associated with other spondylopathies, such as ankylosing spondylitis, and may complicate existing spinal stenosis or inflammatory spine conditions, necessitating careful management and monitoring.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between osteomyelitis and other spinal conditions like discitis or abscesses.
  • Need for comprehensive documentation of clinical findings and imaging results.
  • Potential for co-existing conditions that may complicate coding.
  • Variability in treatment approaches based on severity and patient response.

Audit Risk Factors

  • Inadequate documentation of the infection's origin and extent.
  • Failure to document associated neurological deficits.
  • Misclassification of osteomyelitis as a non-infectious condition.
  • Inconsistent coding of co-existing conditions.

  • It is important to include any relevant details regarding the infection's cause, treatment, and any associated conditions

Exclusion Criteria

Do NOT use M46.2 When
  • Exclusion criteria include conditions that do not involve infection of the vertebrae
