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

This code signifies a break in the upper part of a finger bone, specifically the phalanx closest to the palm, that has shifted out of its normal alignment. The fracture is open, meaning the skin and soft tissue have been compromised, exposing the bone to the outside environment. This code is used for the initial treatment of such an injury when the specific finger involved is not documented.

Apply this code when a patient presents with a newly diagnosed, open, displaced fracture of a proximal phalanx, and the medical record does not specify which finger (e.g., thumb, index, middle, ring, or little) is affected. This is appropriate for the initial surgical repair or other definitive treatment of the open fracture.

• Ensure documentation clearly states "displaced" and "open fracture" for accurate code assignment.
• Only use this code for the initial encounter; subsequent care will require different encounter codes (e.g., D, G, K, P, S).
• Avoid using this code if the specific finger is identified; instead, select a more precise code from the S62.61- series.
