Unspecified fracture of unspecified hand, 7thB

This code signifies a fracture of any bone within the hand where the specific bone involved is not documented, and the fracture has broken through the skin. It indicates the initial treatment phase for such an injury, implying the patient is receiving active care for the acute fracture.

Apply this code when documentation clearly states an open hand fracture but lacks specificity regarding the exact carpal, metacarpal, or phalangeal bone affected. This is appropriate for the initial surgical repair or emergency department visit for the acute injury.

• Only use when the specific hand bone fractured is truly unknown or not documented.
• Ensure "open fracture" is explicitly stated or clearly implied by the clinical scenario (e.g., wound communicating with the fracture site).
• Pair with an external cause code (e.g., V00-Y99) to describe the circumstances of the injury.
