Disp fx of distal phalanx of unsp thumb, init for clos fx

This code describes a break in the bone at the very tip of the thumb, specifically when the bone fragments are no longer aligned. It indicates that this is the first time the patient is being treated for this injury, and the skin over the fracture remains intact.

Apply this code for a patient presenting with a newly diagnosed, non-aligned fracture of the most distal bone in their thumb. This is appropriate when the injury is acute and there is no open wound communicating with the fracture site.

• Ensure documentation specifies "displaced" and "distal phalanx" of the thumb.
• Confirm the encounter is for initial treatment of the closed fracture.
• If the thumb later requires follow-up care or develops complications, a different subsequent encounter or sequela code will be necessary.
