Code Description

ICD-10 M43.3 is a billable code used to indicate a diagnosis of recurrent atlantoaxial dislocation with myelopathy.

Key Diagnostic Point:

Recurrent atlantoaxial dislocation with myelopathy is a condition characterized by the abnormal displacement of the first cervical vertebra (atlas) relative to the second cervical vertebra (axis), leading to neurological deficits due to spinal cord compression. This dislocation can occur due to trauma, congenital anomalies, or degenerative diseases. Myelopathy, which refers to spinal cord dysfunction, manifests as weakness, sensory changes, and coordination difficulties. Patients may present with neck pain, limited range of motion, and neurological symptoms such as tingling or numbness in the extremities. Diagnosis typically involves imaging studies such as MRI or CT scans to visualize the dislocation and assess the degree of spinal cord compression. Treatment may include conservative management with physical therapy or surgical intervention, such as spinal fusion, to stabilize the cervical spine and alleviate pressure on the spinal cord. The recurrent nature of this condition necessitates careful monitoring and management to prevent further neurological deterioration.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires detailed documentation of neurological symptoms and their severity.
  • Involves understanding of spinal anatomy and the implications of dislocation.
  • May require additional codes for associated conditions or complications.
  • Documentation must clearly differentiate between recurrent dislocation and other types of dislocation.

Audit Risk Factors

  • Inadequate documentation of neurological deficits.
  • Failure to specify recurrent nature of the dislocation.
  • Lack of imaging studies to support diagnosis.
  • Improper linkage of diagnosis to surgical procedures.
