External constriction, right thigh, sequela

This code signifies a long-term or late effect resulting from an external constriction injury to the right thigh. This could include chronic pain, nerve damage, circulatory issues, or tissue changes that persist after the initial constricting force has been removed. The sequela indicates that the acute injury has resolved, but its lasting consequences remain.

Use this code when documenting a patient presenting with residual symptoms or conditions in their right thigh directly attributable to a past external constriction injury. Examples include chronic lymphedema, persistent paresthesia, or scar contracture in the right thigh following a prior tourniquet application, tight binding, or entrapment.

• Always code the specific nature of the sequela (e.g., chronic pain, nerve damage) first, followed by this sequela code.
• Ensure documentation clearly links the current condition to a past external constriction injury of the right thigh.
• This "S" extension indicates a sequela; do not use for acute or initial injury encounters.
