External constriction, unspecified lesser toe(s), sequela

This code describes a lasting issue of external pressure or constriction affecting one or more of the lesser toes (digits 2-5) of the left foot. It indicates that the constriction is no longer an acute event but has resulted in a chronic or residual condition. The specific cause of the constriction is not identified.

This code is appropriate for documenting the long-term effects of external constriction on the lesser toes, such as from ill-fitting shoes, tight bandages, or other external forces, after the initial acute phase has passed. It is used when the patient presents with ongoing symptoms or complications directly attributable to a past constrictive event.

• Always assign a seventh character of "S" (sequela) to indicate a late effect.
• Ensure documentation clearly supports a chronic or residual condition rather than an acute injury.
• Look for additional codes to specify the underlying cause of the constriction if known and still relevant, or any resulting complications (e.g., nerve damage, skin breakdown).
