Pathological dislocation of right ankle, NEC

This code signifies a spontaneous or atraumatic dislocation of the right ankle joint, meaning it occurs without significant external force or injury. It indicates an underlying pathological process, such as joint instability due to disease, tumor, or congenital anomaly, rather than a traumatic event.

Apply this code when documentation clearly states a pathological dislocation of the right ankle. This includes cases where the dislocation is recurrent due to chronic instability, or is a manifestation of a systemic disease affecting joint integrity. Supporting documentation should rule out acute trauma as the primary cause.

• Differentiate from traumatic dislocations (S93.0- series) and recurrent dislocations due to instability (M24.471) where the underlying cause isn't explicitly pathological.
• Always code the underlying pathological condition first, if known and documented, as this dislocation is a manifestation of that primary disease.
• Ensure laterality is correctly identified (right ankle in this case); codes exist for left (M24.372) and unspecified (M24.379) ankles.
