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

This code describes a fracture of the fifth metacarpal bone in the left hand where the specific type of fracture is not documented. It indicates that the patient is in a subsequent phase of care for this injury, and the fracture is not healing at the expected rate. This suggests ongoing medical management for a delayed union.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed, unspecified left fifth metacarpal fracture is experiencing delayed healing. This includes situations where the physician is monitoring the fracture's progress, adjusting treatment plans, or performing procedures related to the delayed union. It should be used after the initial treatment phase.

• Ensure documentation clearly states "delayed healing" for the left fifth metacarpal fracture.
• Verify that the encounter is for follow-up care, not the initial treatment.
• Confirm that the specific type of fifth metacarpal fracture is not specified in the medical record.
