Nondisp fx of shaft of 1st MC bone, unsp hand, 7thP

This code signifies a previously treated fracture of the main body (shaft) of the first metacarpal bone (thumb) that has healed in an imperfect or misaligned position. The initial break was not displaced, meaning the bone fragments remained in their normal anatomical alignment. This code is used when the patient is seen for ongoing care related to this malunited fracture.

Apply this code when a patient presents for follow-up care, rehabilitation, or evaluation of complications related to a malunited nondisplaced shaft fracture of the first metacarpal. This includes scenarios where the malunion is causing functional impairment, pain, or cosmetic concerns. It is appropriate for any encounter after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" and specifies the "shaft" of the first metacarpal.
• Verify that the original fracture was documented as "nondisplaced" to accurately use this specific code.
• This code indicates a subsequent encounter; do not use for the initial treatment of the fracture or for nonunion.
