Disp fx of prox phalanx of l little finger, init for opn fx

This code signifies a break in the bone closest to the hand in the left little finger, where the bone fragments are no longer in their normal alignment. The fracture has broken through the skin, exposing the bone to the outside environment. This code is used for the initial treatment phase of such an injury.

Apply this code when documenting the first encounter for a patient presenting with an open, displaced fracture of the proximal phalanx of their left fifth digit. This includes initial evaluation, surgical repair, or other definitive treatment for the acute injury. It is appropriate for emergency department visits or initial orthopedic consultations.

• Ensure documentation clearly specifies "left little finger" and "proximal phalanx" to support this specific code.
• The "B" seventh character indicates an initial encounter for an open fracture, requiring careful review of wound status.
• Verify that the fracture is indeed displaced; if not, a different code for a non-displaced fracture would be appropriate.
