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

This code describes a fracture of the base of the third metacarpal bone in the left hand that was initially nondisplaced but has healed improperly, resulting in malunion. The patient is currently receiving follow-up care for this previously treated fracture.

This code is appropriate for encounters where a patient is being managed for a malunited fracture of the base of the left third metacarpal. This includes follow-up appointments, physical therapy, or surgical intervention to address the malunion. It indicates that the fracture has already been treated and is now in a healing phase with an unfavorable outcome.

• Ensure documentation specifies "malunion" and not "nonunion" or "delayed union" for this specific code.
• Verify the laterality (left hand) and the specific metacarpal bone (third) are clearly documented.
• Confirm this is a "subsequent encounter" for the fracture, indicating ongoing care after initial treatment.
