Nondisp fx of shaft of 5th MC bone, l hand, 7thK

This code signifies a fracture of the long, central part of the fifth metacarpal bone in the left hand that is not displaced. It specifically indicates that the fracture has not healed properly and is being addressed in a subsequent encounter. The "nonunion" aspect means the bone fragments have failed to unite after the expected healing period.

Use this code when documenting follow-up care for a patient with a previously diagnosed left fifth metacarpal shaft fracture that shows evidence of nonunion. This would apply to scenarios where the patient is undergoing further treatment, evaluation, or management for the unhealed fracture. It is appropriate for encounters after the initial treatment phase.

• Ensure the documentation clearly specifies "nonunion" and the left hand's fifth metacarpal shaft.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture is nondisplaced; displaced fractures use different codes.
