Code Description

ICD-10 S13.160 is a billable code used to indicate a diagnosis of subluxation of c5/c6 cervical vertebrae.

Key Diagnostic Point:

Subluxation of the C5/C6 cervical vertebrae refers to a partial dislocation of the cervical spine at the fifth and sixth vertebrae. This condition can result from trauma, such as a fall, motor vehicle accident, or sports injury, leading to misalignment of the vertebrae. Patients may present with neck pain, limited range of motion, and neurological symptoms such as tingling or weakness in the arms. The mechanism of injury often involves sudden impact or rotational forces that exceed the normal range of motion of the cervical spine. Diagnosis typically involves a thorough clinical examination, imaging studies such as X-rays or MRI to assess the alignment of the vertebrae and any associated soft tissue injuries. Management may include conservative treatment such as physical therapy, cervical collars, or in more severe cases, surgical intervention to realign the vertebrae and stabilize the spine. Complications can include chronic pain, neurological deficits, or the potential for further injury if not properly managed.

Emergency Medicine

Documentation Requirements

Documentation must include a detailed account of the injury mechanism, initial assessment findings, and any imaging results.

Common Clinical Scenarios

Trauma cases involving falls, sports injuries, or vehicular accidents.

Billing Considerations

Ensure that neurological assessments are documented, as they are critical for determining the severity of the injury.

Surgery

Documentation Requirements

Operative reports must detail the surgical approach, findings, and any corrective measures taken.

Common Clinical Scenarios

Surgical intervention for severe subluxation requiring stabilization or decompression.

Billing Considerations

Document any pre-existing conditions that may affect surgical outcomes.

Frequently Asked Questions

What is the difference between subluxation and dislocation?

Subluxation refers to a partial dislocation where the joint surfaces are still in partial contact, while dislocation is a complete separation of the joint surfaces.
