Other recurrent atlantoaxial dislocation

This code signifies a condition where the atlantoaxial joint (C1-C2 vertebrae) repeatedly dislocates or subluxates, but the specific type of dislocation does not fit into other defined categories. It implies an instability of this crucial cervical spine joint, leading to recurrent episodes of misalignment.

Use this code when documentation clearly indicates recurrent atlantoaxial instability or dislocation that is not congenital, traumatic, or due to inflammatory arthropathy. This code is appropriate for chronic or recurring subluxations or dislocations of the C1-C2 joint where the etiology is not otherwise specified as a distinct type. Supporting documentation should detail the recurrent nature and the specific joint involved.

• Ensure the documentation specifies "recurrent" and "atlantoaxial" to differentiate from acute or single episodes.
• Do not use for congenital atlantoaxial instability (Q05.0-Q05.9) or traumatic dislocations (S13.1XXA-S13.1XXS).
• Consider sequencing with codes for associated neurological deficits or pain, if documented.
