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

This code signifies a non-displaced break in the neck of any metacarpal bone other than the first (thumb) or fifth (pinky) metacarpals. "Nondisplaced" indicates the bone fragments are still in their normal anatomical alignment. The "subsequent encounter" denotes that this code is used for follow-up care during the healing phase of the fracture, and "routine healing" implies no complications are present.

Apply this code when a patient presents for a follow-up visit related to a previously diagnosed, non-displaced fracture of the neck of the second, third, or fourth metacarpal. This is appropriate for routine check-ups, cast changes, or physical therapy evaluations during the expected healing period.

• Ensure the documentation specifies "nondisplaced" and identifies the fracture as being in the neck of a metacarpal other than the thumb or pinky.
• Verify this is a subsequent encounter for routine healing; if complications are present, a different seventh character is required.
• Always sequence this code after any primary injury or condition if applicable, but it will often be the primary diagnosis for follow-up visits.
