Unsp fracture of metacarpal bone, subs for fx w routn heal

This code signifies a follow-up visit for a fracture of a metacarpal bone, other than the thumb or little finger, where the specific metacarpal involved is not documented. At this stage, the fracture is healing as expected without complications.

Use this code for subsequent encounters when a patient is receiving routine follow-up care for an unspecified metacarpal fracture (excluding the first and fifth metacarpals) that is progressing well. This applies when the initial injury was not precisely localized to a specific metacarpal bone and the healing process is uncomplicated.

• Ensure documentation specifies "subsequent encounter" and "routine healing."
• Verify that the fracture is not of the first (thumb) or fifth (little finger) metacarpal, as those have more specific codes.
• If the healing is delayed, nonunion, or malunion, a different seventh character is required.
