Oth fracture of fourth metacarpal bone, left hand, init

This code signifies a fracture of the fourth metacarpal bone in the left hand, excluding those specifically classified as Boxer's fractures. It indicates a break in the bone that has not broken through the skin, and this is the first time the patient is receiving treatment for this specific injury.

This code is appropriate for documenting a newly diagnosed, closed fracture of the left fourth metacarpal bone, such as those resulting from a fall, direct impact, or crushing injury. It should be used when the fracture is not explicitly identified as a Boxer's fracture (fracture of the fifth metacarpal neck).

• Ensure the documentation clearly specifies the fourth metacarpal and the left hand.
• Verify that the fracture is indeed closed and that this is the initial encounter for treatment.
• Distinguish carefully between fourth and fifth metacarpal fractures, as Boxer's fractures have a dedicated code.
