Oth fracture of base of skull, subs for fx w delay heal

This code signifies a fracture located at the base of the skull, excluding the occipital condyle, that is currently undergoing a healing process but is progressing slower than anticipated. It indicates that the patient has previously been treated for this specific fracture and is now presenting for follow-up care related to its delayed union.

Use this code for patients presenting for subsequent care of a previously diagnosed base of skull fracture (excluding occipital condyle) where medical documentation explicitly states "delayed healing," "slow union," or similar terminology. Documentation should confirm the fracture location and the ongoing nature of the healing process.

• Ensure documentation clearly specifies "delayed healing" for the base of skull fracture; otherwise, an initial or routine subsequent encounter code may be more appropriate.
• Distinguish from nonunion (S02.19XK) or malunion (S02.19XP), which represent different complications of fracture healing.
• Always sequence this code as the primary diagnosis if the delayed healing is the reason for the encounter.
