Nondisp fx of 1st metatarsal bone, unsp ft, init for opn fx

This code signifies a break in the first metatarsal bone (the long bone connecting the big toe to the midfoot) that has not shifted out of its normal alignment. It specifically indicates that the skin and soft tissue surrounding the fracture site were broken, exposing the bone to the outside environment.

This code is appropriate for the initial treatment of an open, nondisplaced fracture of the first metatarsal when the affected foot is not specified. This would include situations like a crush injury or a penetrating wound that resulted in the fracture and skin breach.

• Ensure documentation clearly states "nondisplaced" and "open fracture" for the first metatarsal.
• Confirm this is the patient's initial encounter for this specific injury. Subsequent care would require a different encounter character.
• If the foot (left or right) is documented, a more specific code should be used.
