Nondisp fx of hook pro of hamate bone, l wrs, 7thB

This code signifies a break in the hook-shaped projection of the hamate bone in the left wrist. The fracture is not displaced, meaning the bone fragments are still in their normal anatomical alignment. It also indicates that the skin and soft tissue overlying the fracture were broken, exposing the bone to the outside environment.

This code is appropriate for the initial treatment of an open, non-displaced fracture of the hook of the hamate bone in the left wrist. This typically occurs due to direct trauma to the palm, such as from a fall onto an outstretched hand or impact from a sports implement. It is used when the patient is first presenting for care of this specific injury.

• Ensure documentation clearly specifies "left wrist" and "nondisplaced" for accurate coding.
• The "B" seventh character indicates an initial encounter for an open fracture; verify that the medical record supports an open injury.
• Distinguish from closed fractures or displaced fractures, which would require different codes and seventh characters.
