Fx unsp phalanx of l little finger, subs for fx w nonunion

This code indicates a fracture of an unspecified phalanx in the left little finger that has failed to heal properly. The "nonunion" aspect signifies that the bone fragments have not united after a sufficient healing period, requiring further medical intervention. This is a follow-up encounter for this specific complication.

Use this code when a patient presents for ongoing management or treatment of a previously diagnosed left little finger phalanx fracture that has been confirmed as a nonunion. This applies to situations such as follow-up appointments, surgical planning for nonunion repair, or conservative management of a persistent nonunion.

• Ensure documentation clearly specifies "nonunion" of the fracture.
• Verify the laterality (left) and the specific digit (little finger) are accurately documented.
• This code is for a subsequent encounter; an initial encounter for the nonunion would use a different seventh character.
