Dislocation of unsp interphaln joint of l idx fngr, init

This code signifies a complete displacement of the bones forming an interphalangeal joint within the left index finger, where the specific joint (proximal or distal) is not documented. This injury disrupts the normal articulation and function of the affected finger segment.

Apply this code when documentation clearly indicates a dislocation of the left index finger's interphalangeal joint, but the specific joint involved (e.g., PIP or DIP) is not specified. This is appropriate for the initial treatment of such an injury, typically seen in emergency department visits or initial orthopedic consultations.

• Ensure the documentation explicitly states "unspecified" interphalangeal joint if the specific joint is not identified.
• Verify the encounter is the "initial encounter" for this specific injury; subsequent care will require a different seventh character.
• Confirm the laterality is "left index finger" as specified by the code.
