Dislocation of unsp interphalangeal joint of finger, init

This code signifies a complete separation of the bones forming an interphalangeal joint in any finger other than the thumb, where the specific joint (proximal or distal) is not documented. This injury involves the disruption of the joint capsule and ligaments, leading to abnormal alignment of the phalanges.

Use this code when a patient presents with a dislocated interphalangeal joint in the index, middle, ring, or little finger, and the medical record does not specify whether it's the proximal interphalangeal (PIP) or distal interphalangeal (DIP) joint. This code is appropriate for the initial visit for this injury, such as in an emergency department or initial orthopedic consultation.

• Ensure the documentation clearly states "unspecified interphalangeal joint" or lacks specificity regarding PIP vs. DIP.
• Confirm the dislocation occurred in a finger other than the thumb.
• Verify this is the patient's first encounter for this specific injury to use the "A" (initial encounter) seventh character.
