Nondisp fx of shaft of unsp metacarpal bone, init for opn fx

This code describes a break in the main body (shaft) of one of the metacarpal bones in the hand, where the bone fragments remain in their normal alignment. It specifically indicates that the skin and soft tissue overlying the fracture are also broken, exposing the bone to the outside environment, and that this is the first time the patient is receiving treatment for this injury.

Use this code for a patient presenting with a newly diagnosed, open fracture of the shaft of an unspecified metacarpal bone that has not been displaced. This typically occurs following trauma where the skin is compromised, such as a crush injury or a direct impact with a sharp object.

• Ensure documentation clearly states an "open" fracture and specifies the "shaft" of the metacarpal.
• Verify that the fracture is "nondisplaced" and that this is the "initial encounter" for treatment.
• If the specific metacarpal bone is known, a more precise code should be selected.
