Unsp fx fifth MC bone, right hand, subs for fx w delay heal

This code signifies an unconfirmed fracture of the fifth metacarpal bone in the right hand that is not healing at the expected rate. It indicates that the patient is presenting for follow-up care for this specific injury, and the healing process is prolonged.

This code is appropriate for subsequent encounters when a patient with an initially unspecified right fifth metacarpal fracture is experiencing delayed union or nonunion. It should be used when the provider documents that the fracture is not healing as anticipated and requires ongoing management.

• Ensure documentation explicitly states "delayed healing" or similar terminology for the fracture.
• Verify laterality (right hand) and bone (fifth metacarpal) are clearly documented.
• This code is for subsequent encounters; an initial encounter would use a different code.
