The medical record should clearly indicate that the healing process is prolonged beyond the typical timeframe for such an injury. This code is appropriate for subsequent visits where delayed healing is the primary focus of the encounter.

• Ensure documentation explicitly states "delayed healing" or similar terminology for the skull fracture.
• Do not use this code for initial encounters or for fractures healing normally.
• Always sequence this code after any associated external cause codes (e.g., fall, assault).
