Nondisp fx of base of fourth MC bone, right hand, init

This code signifies a break in the base of the fourth metacarpal bone in the right hand that has not shifted out of its normal alignment. It indicates a closed fracture, meaning the skin over the fracture site remains intact. This is the initial encounter for this specific injury.

Use this code for a patient presenting with a newly diagnosed, non-displaced fracture at the base of their right fourth metacarpal. This applies when the fracture is confirmed by imaging and there is no open wound communicating with the fracture site. It is appropriate for the first visit related to this injury.

• Ensure documentation specifies "nondisplaced" and "base of fourth metacarpal" on the right hand.
• Verify that the encounter is indeed the initial treatment for this specific fracture.
• Confirm the fracture is closed; if open, a different code would be required.
