Oth fx fourth MC bone, left hand, subs for fx w delay heal

This code signifies a fracture of the fourth metacarpal bone in the left hand, which is currently in the healing phase but is experiencing a delay in the expected healing process. It indicates that the patient is receiving ongoing care for this specific fracture, and the healing is not progressing at a normal rate.

This code is appropriate for follow-up encounters where a patient is being treated for a left fourth metacarpal fracture that is not healing as anticipated. This includes situations where imaging shows incomplete callus formation or persistent fracture lines beyond the typical healing timeframe, and the patient is still under active management for the fracture.

• Ensure documentation clearly specifies "delayed healing" for the fourth metacarpal fracture.
• Verify the fracture is of the left hand and not a different metacarpal.
• This code is for a subsequent encounter, not the initial treatment of the fracture.
