Nondisp fx of base of 3rd MC bone, l hand, 7thG

This code signifies a fracture at the base of the third metacarpal bone in the left hand that has not shifted from its anatomical position. The patient is in a later stage of care, and the fracture is not healing at the expected rate.

Apply this code when documenting follow-up care for a left third metacarpal base fracture that was initially nondisplaced, and the physician notes delayed union or non-progression of healing. This typically occurs during subsequent visits after the initial treatment, when the fracture is still present but not healing as anticipated.

• Ensure documentation explicitly states "nondisplaced" and "delayed healing" for the left third metacarpal base.
• Verify the encounter is for follow-up care, not the initial treatment.
• Confirm the laterality is "left hand" to avoid coding errors.
