Oth disp fx of base of 1st MC bone, l hand, 7thD

This code signifies a fracture at the base of the first metacarpal bone (thumb) in the left hand, where the bone fragments are no longer in their normal anatomical alignment. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, which is currently healing as expected without complications.

This code is appropriate for documenting follow-up visits for a left thumb metacarpal base fracture that was initially displaced and is now undergoing routine healing. This includes appointments for cast changes, wound checks, or physical therapy where the primary focus is monitoring the fracture's uncomplicated recovery.

• Ensure documentation specifies "left hand" and "base of first metacarpal" to support this specific code.
• Confirm the fracture is healing routinely; if delayed healing or nonunion is present, a different subsequent encounter code would be necessary.
• This code is for displaced fractures; an undisplaced fracture would require a different code.
