Sprain of ligaments of cervical spine, initial encounter

This code signifies an injury to the ligaments supporting the cervical spine, commonly known as a neck sprain. It involves the stretching or tearing of these fibrous tissues, often resulting from sudden, forceful movements of the head and neck.

Apply this code for patients presenting with acute neck pain, stiffness, and limited range of motion following a traumatic event such as a whiplash injury from a motor vehicle accident, a fall, or sports-related trauma. Documentation should clearly state a diagnosis of cervical ligament sprain and indicate the initial encounter for this specific injury.

• Ensure documentation specifies "sprain" of ligaments, not a fracture or dislocation, which would require different codes.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Distinguish from muscle strain (e.g., S16.1XXA) or unspecified neck pain (e.g., M54.2), as this code is specific to ligamentous injury.
