Disp fx of medial cuneiform of unsp foot, init for opn fx

This code signifies a break in the medial cuneiform bone, one of the tarsal bones in the midfoot, where the bone fragments are no longer in their normal anatomical alignment. This specific injury involves an open wound, meaning the skin and soft tissues have been compromised, exposing the fracture site to the outside environment.

Use this code for a patient presenting with a newly diagnosed, displaced fracture of the medial cuneiform in an unspecified foot, where there is an open wound communicating with the fracture. This code is appropriate for the initial treatment of such an open fracture, prior to definitive surgical or non-surgical management.

• Ensure documentation clearly specifies "displaced" and "open fracture" for the medial cuneiform.
• The "B" in the seventh character indicates an initial encounter for an open fracture; subsequent encounters will require different seventh characters.
• If the laterality (left or right foot) is known, a more specific code should be used.
