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

This code describes a fracture involving the shaft of a metacarpal bone, excluding the thumb, where the bone fragments remain in their normal anatomical alignment. This specific code is used when the patient is seen for follow-up care and the fracture is healing as expected without complications.

This code is appropriate for subsequent encounters when a patient is receiving routine follow-up for a previously diagnosed, nondisplaced shaft fracture of a metacarpal other than the first. It indicates that the fracture is progressing through its normal healing stages. Use this code for visits such as cast changes, follow-up X-rays showing callus formation, or routine physical therapy assessments during the healing phase.

• Ensure the documentation specifies "nondisplaced" and involves the "shaft" of a metacarpal other than the thumb.
• Verify that the encounter is for follow-up care and not the initial treatment of the fracture.
• Confirm that the healing process is described as "routine" or uncomplicated in the medical record.
