Fx unsp tarsal bone(s) of right foot, subs for fx w nonunion

This code signifies a fracture of one or more tarsal bones in the right foot that has not healed properly, despite previous treatment. The "nonunion" aspect indicates that the bone ends have failed to unite and consolidate, leading to persistent instability or pain. This diagnosis is made during a subsequent visit for ongoing management of the unhealed fracture.

Apply this code when documenting a patient's follow-up visit for a right foot tarsal bone fracture that has been diagnosed with nonunion. This typically occurs after initial treatment attempts (e.g., casting, surgery) have failed to achieve bone healing. It is used when the patient is receiving further treatment or evaluation for the unhealed fracture.

• Ensure documentation clearly states "nonunion" and specifies the right foot.
• Confirm that this is a subsequent encounter for the fracture, not the initial injury.
• Do not use this code if the specific tarsal bone is known; instead, use a more specific code from the S92.2 series.
