Dislocation of C5/C6 cervical vertebrae, initial encounter

This code signifies a complete displacement of the C5 vertebra from the C6 vertebra in the cervical spine. This injury typically involves damage to the ligaments and joint capsules that normally stabilize these vertebrae. Patients often present with severe neck pain, limited range of motion, and potential neurological deficits depending on the degree of spinal cord involvement.

Apply this code for the initial treatment of a patient presenting with a documented C5/C6 cervical vertebral dislocation. This includes emergency department visits, initial hospital admissions, or the first encounter with a healthcare provider for this specific injury. It is appropriate when the dislocation is confirmed by imaging studies such as X-rays, CT scans, or MRI.

• Ensure documentation clearly specifies the C5/C6 level and confirms a true dislocation, not just a subluxation.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Always code any associated spinal cord injury (e.g., contusion, laceration) separately using appropriate codes.
