Disp fx of shaft of MC bone, subs for fx w routn heal

This code signifies a break in the middle portion (shaft) of a metacarpal bone other than the first (thumb) or fifth (pinky) metacarpal, where the bone fragments are not properly aligned. This specific code is used when the patient is receiving follow-up care for this fracture and the healing process is progressing as expected without complications.

Apply this code for patients presenting for routine follow-up appointments after an initial diagnosis of a displaced shaft fracture of the second, third, or fourth metacarpal. This includes scenarios such as cast changes, repeat X-rays to monitor healing, or physical therapy evaluations during the normal recovery period. It indicates that the fracture is on a typical healing trajectory.

• Ensure the documentation specifies a "displaced" fracture of the shaft of a metacarpal other than the thumb or pinky.
• Confirm the encounter is for subsequent care and that healing is described as "routine" or "uncomplicated."
• Do not use this code for initial encounters or if the healing is delayed, nonunion, or malunion; different codes apply for those situations.
