External constriction of left index finger, sequela

This code signifies a lasting consequence or complication resulting from an external force that caused abnormal compression or narrowing of the left index finger. This could manifest as chronic pain, nerve damage, circulatory issues, or functional impairment that persists after the initial injury has healed.

Apply this code when documenting a current condition of the left index finger that is a direct, long-term result of a past external constriction injury. This is appropriate for follow-up visits where the sequelae are being managed, or when a patient presents with chronic issues stemming from such an event.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., chronic pain, nerve entrapment).
• Ensure documentation clearly links the current condition to a previous external constriction injury of the left index finger.
• The "S" seventh character indicates a sequela, meaning the initial injury has resolved but its effects persist.
