External constriction of left wrist, sequela

This code indicates a long-term or late effect resulting from an external constriction injury to the left wrist. This could manifest as chronic pain, stiffness, nerve damage, or circulatory issues that persist after the initial constricting force has been removed and the acute injury has resolved. The sequela implies a permanent or residual condition directly attributable to the past external constriction.

Apply this code when documenting a patient presenting with a current, ongoing problem in the left wrist that is a direct consequence of a previously sustained external constriction injury. This is appropriate for follow-up visits where the initial acute injury has healed, but residual symptoms or complications persist. Examples include chronic carpal tunnel syndrome or complex regional pain syndrome developing after a tight cast or restraint.

• Always sequence this code after the code for the specific sequela (e.g., chronic pain, nerve damage) if known.
• Ensure documentation clearly links the current wrist condition to a past external constriction event.
• Do not use for acute or initial external constriction injuries; this code is exclusively for late effects.
