Nondisp fx of shaft of 3rd MC bone, r hand, init for opn fx

This code describes a break in the middle portion (shaft) of the third metacarpal bone in the right hand. The fracture fragments are still in their normal anatomical alignment (nondisplaced), and the skin and soft tissues surrounding the fracture site have been compromised, exposing the bone to the external environment.

Use this code for initial encounters when a patient presents with an open fracture of the shaft of the right third metacarpal. This typically occurs due to direct trauma, such as a crush injury or a penetrating wound, where the bone has broken and pierced through the skin.

• Always confirm laterality (right hand) and the specific metacarpal involved (third).
• The "B" seventh character indicates an initial encounter for an open fracture; ensure appropriate external cause codes are also reported.
• Distinguish between open and closed fractures, as this significantly impacts code selection.
