Unsp fx first MC bone, left hand, subs for fx w routn heal

This code signifies a fracture of the first metacarpal bone (thumb) in the left hand, where the specific type of fracture is not documented. It indicates that the patient is in a follow-up phase of care, and the fracture is healing as expected without complications.

Apply this code when a patient presents for a follow-up visit for a left first metacarpal fracture that was previously diagnosed, and the provider's documentation confirms routine healing. This is appropriate for subsequent encounters after the initial treatment, such as cast changes or progress checks.

• Ensure the documentation specifies "left hand" and "first metacarpal."
• Verify that the encounter is for follow-up care and not the initial treatment.
• Confirm that the healing process is described as routine or uncomplicated.
