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

This code signifies a fracture of the fourth metatarsal bone that has not shifted from its normal anatomical position. The injury is located in an unspecified foot, and the patient is presenting for follow-up care where the fracture has failed to heal properly (nonunion).

Apply this code when documenting ongoing management of a fourth metatarsal fracture that was initially nondisplaced, but subsequent imaging or clinical assessment confirms a nonunion. This is appropriate for patients returning for further treatment, such as surgical intervention or specialized casting, due to the lack of healing.

• Ensure documentation clearly states "nondisplaced" and "nonunion" for the fourth metatarsal.
• Verify that the encounter is for follow-up care related to the fracture's nonunion, not the initial injury.
• Always check for laterality (left or right foot) if specified in the medical record; "unspecified foot" should only be used when laterality is truly unknown.
