External constriction of left little finger, sequela

This code indicates a permanent or late effect resulting from external constriction of the left little finger. This could manifest as chronic pain, nerve damage, circulatory issues, or deformities that persist after the initial constricting force has been removed.

Assign this code when documenting a long-term complication or residual condition directly attributable to a past external constriction injury of the left little finger. This is appropriate for follow-up encounters where the acute injury has resolved, but sequelae remain.

• Always use this code as a secondary diagnosis, following the primary diagnosis describing the specific sequela (e.g., chronic pain, nerve palsy).
• Ensure documentation clearly links the current condition to a past external constriction injury of the left little finger.
• Do not use for acute or initial encounters of external constriction; those require acute injury codes.
