Nondisp fx of base of second MC bone, left hand, 7thP

This code signifies a fracture at the base of the second metacarpal bone in the left hand that has not shifted from its original position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed fracture, and "malunion" specifies that the bone is healing in an incorrect anatomical alignment.

Apply this code when a patient presents for ongoing treatment, such as cast changes, physical therapy, or imaging, for a left second metacarpal base fracture that has been documented as healing with malunion. This code is appropriate for encounters occurring after the initial treatment phase, where the malunion is the focus of the current visit.

• Ensure documentation explicitly states "left hand," "second metacarpal," "base," "nondisplaced," and "malunion."
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• Confirm the malunion is clearly documented by the physician, often supported by imaging reports.
