Disp fx of 4th metatarsal bone, unsp ft, 7thK

This code signifies a fracture of the fourth metatarsal bone that has not healed properly (nonunion) and where the bone fragments are no longer in their normal anatomical alignment (displaced). This specific code is used for encounters following the initial treatment, indicating ongoing management of the nonunion. The affected foot is not specified.

Apply this code for patients presenting for follow-up care, re-evaluation, or treatment of a previously diagnosed displaced fourth metatarsal fracture that has failed to unite. This includes scenarios where surgical intervention for nonunion is being planned or has already occurred, or when conservative management of the nonunion is ongoing.

• Ensure documentation clearly specifies "nonunion" and "displaced" for the fourth metatarsal.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the laterality (left or right foot) is not specified in the medical record; if it is, a more specific code should be used.
