Nondisp fx of middle phalanx of unsp lesser toe(s), 7thK

This code signifies a fracture of the middle bone of one or more of the smaller toes (not the big toe) that has not shifted out of alignment. The patient is receiving follow-up care for this fracture, and the bone fragments have failed to unite properly. This indicates a complication in the healing process.

Apply this code when documentation confirms a nonunion of a nondisplaced middle phalanx fracture of a lesser toe during a subsequent encounter. This is appropriate for ongoing management, such as casting changes, physical therapy, or surgical planning for the nonunion. It should be used after the initial treatment phase.

• Ensure documentation explicitly states "nonunion" and "nondisplaced" for a middle phalanx fracture of a lesser toe.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
• Do not use for displaced fractures or fractures of the great toe.
