Disp fx of navicular of right foot, init for opn fx

This code signifies a break in the navicular bone of the right foot, where the bone fragments are no longer in their normal alignment. It specifically indicates that the fracture has broken through the skin, exposing the bone to the outside environment, and that this is the patient's initial presentation for treatment of this injury.

This code is appropriate for documenting a patient presenting to the emergency department or clinic for the first time with an open, displaced fracture of the right foot's navicular bone. It would be used when the physician's documentation clearly states an open fracture and specifies the right foot.

• Always verify laterality (right vs. left foot) from the physician's documentation.
• Confirm "open" vs. "closed" fracture status, as this significantly impacts code selection.
• The "B" seventh character indicates an initial encounter for an open fracture; ensure this aligns with the patient's treatment phase.
