Oth nondisp fx of base of 1st MC bone, unsp hand, 7thG

This code signifies a non-displaced fracture at the base of the first metacarpal bone (thumb) that is not otherwise specified, and the patient is presenting for follow-up care due to delayed healing of the fracture. The specific hand affected is not documented.

Apply this code when a patient with a previously diagnosed, non-displaced fracture of the first metacarpal base is seen for a subsequent visit, and the physician notes that the fracture is not healing at the expected rate. This would include scenarios where the patient is still experiencing pain, swelling, or limited function beyond the typical healing timeframe, and imaging confirms the fracture is still present and non-displaced.

• Ensure documentation clearly states "delayed healing" for this subsequent encounter.
• Verify that the fracture is explicitly described as "nondisplaced" and at the "base of the first metacarpal."
• Do not use this code for initial encounters or for fractures that are healing normally.
