Oth fracture of fourth metacarpal bone, right hand, init

This code signifies a fracture of the fourth metacarpal bone in the right hand, excluding a Boxer's fracture. It indicates that the skin over the fracture site remains intact (closed fracture) and that this is the first time the patient is receiving active treatment for this specific injury.

Apply this code when documenting a newly diagnosed, non-Boxer's fracture of the right fourth metacarpal. This is appropriate for initial encounters where definitive treatment, such as casting or splinting, is being initiated or planned.

• Ensure documentation specifies the right hand and fourth metacarpal, and explicitly rules out a Boxer's fracture.
• Confirm the fracture is closed; if open, a different seventh character is required.
• The "A" seventh character indicates the initial encounter for active treatment. Subsequent encounters will require different seventh characters.
