Nondisp fx of base of fifth metacarpal bone, left hand, init

This code signifies a break in the base of the fifth metacarpal bone (the bone connecting the little finger to the wrist) in the left hand. The fracture is "nondisplaced," meaning the bone fragments are still in their normal anatomical alignment, and it's being treated for the first time.

Apply this code for initial encounters involving a patient presenting with a newly diagnosed, stable fracture at the base of the left fifth metacarpal. This is appropriate when the fracture does not require surgical intervention to realign the bone fragments and is being managed non-operatively (e.g., casting, splinting).

• Ensure documentation specifies "nondisplaced" and "base of fifth metacarpal" for the left hand.
• This "A" initial encounter suffix is only used for the active treatment phase of the fracture.
• Confirm the fracture is closed; open fractures would require a different code.
