Nondisp fx of nk of 5th MC bone, r hand, 7thK

This code describes a fracture of the neck of the fifth metacarpal bone in the right hand that is not displaced. The key aspect is that the fracture has failed to heal properly, leading to a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for subsequent encounters when a patient is receiving treatment or evaluation for a previously diagnosed nondisplaced fracture of the right fifth metacarpal neck that has developed a nonunion. This would include visits for monitoring, further diagnostic imaging, or planning for surgical intervention to address the nonunion.

• Ensure documentation clearly states "nonunion" to justify the 7th character "K".
• Verify the fracture is specifically of the "neck" of the fifth metacarpal and on the "right" hand.
• This code is for subsequent encounters; an initial encounter would use a different 7th character.
