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

This code signifies a fracture of the first metacarpal bone (thumb) that is out of alignment, in an unspecified hand. The patient is in a follow-up phase where the fracture is healing as expected without complications.

Apply this code for subsequent encounters when a patient with a previously diagnosed displaced first metacarpal fracture is seen for routine follow-up, cast changes, or imaging to monitor normal healing progress. This indicates the initial treatment has been rendered and the bone is mending routinely.

• Ensure the documentation specifies "displaced" and "routine healing" for this specific code.
• Verify the encounter is not for initial treatment or for a delayed/nonunion healing scenario.
• Laterality (left or right hand) is unspecified with this code; if known, a more specific code should be sought.
