Nondisp fx of nk of 1st MC bone, unsp hand, 7thD

This code signifies a fracture of the neck of the first metacarpal bone (thumb) that remains in its normal anatomical position. The "subsequent encounter" indicates the patient is receiving follow-up care for this injury, and "routine healing" suggests the fracture is progressing as expected without complications.

Apply this code when documenting follow-up visits for a previously diagnosed nondisplaced fracture of the thumb's first metacarpal neck. This is appropriate when the physician assesses the healing progress and confirms it is proceeding routinely, such as during cast changes, splint checks, or follow-up X-rays showing callus formation.

• Ensure the documentation explicitly states "nondisplaced" and identifies the "neck" of the first metacarpal.
• Confirm this is a subsequent encounter for ongoing care, not the initial treatment or a visit for complications.
• Verify that the healing process is described as routine, without mention of delayed healing, nonunion, or malunion.
