Oth nondisp fx of 2nd cervcal vert, subs for fx w delay heal

This code signifies a fracture of the second cervical vertebra (axis) that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "G" seventh character indicates that the patient is in a subsequent encounter for this fracture, and the healing process is progressing slower than expected.

Use this code when a patient presents for follow-up care of a previously diagnosed, nondisplaced C2 fracture, and the physician's documentation explicitly states "delayed healing." This typically applies to visits for cast changes, physical therapy, or imaging to monitor healing progress when the fracture has not yet united within the expected timeframe.

• Ensure documentation clearly specifies "nondisplaced" and "delayed healing" for the C2 fracture.
• Do not use for initial encounters or routine healing; reserve for documented complications in healing.
• Consider sequencing with external cause codes (e.g., Y92.9) if the cause of injury is relevant and documented.
