Nondisp fx of nk of 5th MC bone, l hand, 7thK

This code signifies a fracture of the fifth metacarpal bone's neck in the left hand, where the bone fragments remain in their anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed fracture, and "nonunion" specifies that the bone has failed to heal properly after a typical healing period.

Use this code for a patient presenting for ongoing management of a left fifth metacarpal neck fracture that has not united. This would apply during clinic visits for cast changes, physical therapy, or surgical planning for nonunion repair. It is appropriate when the initial treatment has failed to achieve bone healing.

• Ensure documentation clearly states "nondisplaced" and specifies the "neck" of the fifth metacarpal.
• Verify the encounter is for follow-up care of the fracture, not the initial injury.
• Confirm the physician's assessment explicitly mentions "nonunion" as the current status of the fracture healing.
