Displaced fracture of middle phalanx of other finger, 7thK

This code signifies a fracture of the middle phalanx of any finger other than the thumb, where the bone fragments are no longer in their normal alignment. Crucially, this specific code is used when the fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care after initial treatment.

Use this code for patients who have previously been treated for a displaced middle phalanx fracture of a finger (excluding the thumb) and are now returning for evaluation or management of a documented nonunion. This applies to situations where the fracture site shows no signs of healing progression and requires ongoing medical attention.

• Ensure documentation clearly states "nonunion" and "displaced" for a middle phalanx fracture of a finger other than the thumb.
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion; do not use for initial treatment or routine follow-up of a healing fracture.
• Verify the specific finger involved to ensure it's not the thumb, as thumb fractures have different codes.
