Nondisp fx of shaft of 1st MC bone, unsp hand, 7thB

This code signifies a break in the main body (shaft) of the first metacarpal bone (thumb) that has not shifted out of alignment. The fracture is an open type, meaning the skin and soft tissue overlying the fracture site have been compromised, exposing the bone. This code is specifically for the initial treatment of such an injury, regardless of which hand is affected.

Apply this code for patients presenting with a newly diagnosed, non-displaced open fracture of the first metacarpal shaft. This is appropriate when the patient is receiving active treatment for the fracture, such as wound debridement, irrigation, or initial stabilization. It should be used for the first encounter related to this specific injury.

• Ensure documentation clearly states "open fracture" and "nondisplaced" for the first metacarpal shaft.
• Verify that this is indeed the initial encounter for the fracture treatment, not a subsequent visit.
• Do not use this code if the fracture is displaced, involves a different part of the metacarpal, or is a closed fracture.
