Unsp Zone I fracture of sacrum, subs for fx w delay heal

This code signifies a fracture in the upper part of the sacrum (Zone I) where the specific type of fracture is not documented. The patient is in a later stage of care, and the fracture is not healing at the expected rate, requiring continued medical attention.

Apply this code for follow-up encounters of a sacral Zone I fracture that was previously diagnosed, and the physician's documentation explicitly states "delayed healing" or similar terminology indicating a slower-than-normal healing process. This is appropriate when the precise nature of the Zone I fracture (e.g., transverse, vertical) was not specified in the initial diagnosis or subsequent documentation.

• Ensure documentation clearly states "delayed healing" for a subsequent encounter.
• Verify that the fracture location is specifically Zone I of the sacrum.
• Only use this code when the specific type of Zone I fracture remains unspecified.
