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

This code signifies a fracture of the fourth metacarpal bone in the right hand where the specific type of fracture (e.g., transverse, oblique) is not documented. The encounter is for follow-up care, indicating that the fracture is not healing at the expected rate.

This code is appropriate for subsequent encounters when a patient presents with a right fourth metacarpal fracture that is demonstrating delayed union, and the initial fracture type was not specified. It would be used for ongoing management, such as cast changes, physical therapy evaluations, or imaging to assess healing progress.

• Ensure documentation clearly states "delayed healing" or similar terminology for the fracture.
• Verify the laterality (right hand) and the specific metacarpal bone (fourth) are explicitly mentioned.
• Confirm that the initial fracture type was not specified in the medical record to justify "unspecified."
