Unspecified dislocation of unspecified foot, sequela

This code indicates a long-term complication or late effect resulting from a prior, unspecified dislocation of any part of the foot. It signifies that the original injury has resolved, but the patient continues to experience residual symptoms or conditions directly attributable to that past dislocation.

Apply this code when documentation clearly links a current foot condition to a previously sustained, unspecified foot dislocation, and the acute phase of the dislocation has passed. This is appropriate for chronic pain, instability, or functional limitations that are a direct sequela of the old injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, arthritis).
• Ensure the medical record explicitly states the current condition is a "sequela" or "late effect" of a prior foot dislocation.
• Avoid using this code for acute dislocations or when the specific site of the foot dislocation is known; instead, use more specific codes from the S93.3 category.
