Disp fx of distal phalanx of unsp finger, init for opn fx

This code signifies a break in the outermost bone of an unknown finger, where the bone fragments are no longer in their normal alignment. This specific instance indicates that the skin was broken at the fracture site, exposing the bone to the outside environment.

Apply this code when documenting an initial visit for a patient presenting with an open, displaced fracture of the distal phalanx of a finger that is not specified. This is used for the primary treatment of such an injury, prior to definitive care or follow-up.

• Ensure documentation clearly states an "open" fracture and "displaced" fragments.
• Confirm this is the initial encounter for treatment of this specific injury.
• If the specific finger (e.g., thumb, index) is known, a more specific code should be used.
