Unsp Zone I fracture of sacrum, init for clos fx

This code signifies an unspecified fracture located in Zone I of the sacrum. Zone I fractures typically involve the sacral ala, lateral to the sacral foramina, and are often stable. The "initial encounter" and "closed fracture" indicate the patient is receiving active treatment for a fracture that has not broken through the skin.

Use this code for patients presenting with a newly diagnosed, non-open sacral fracture that is clinically or radiographically determined to be in Zone I, but the specific type of fracture (e.g., transverse, oblique) is not documented. This applies to the initial phase of treatment, such as emergency department visits or initial hospital admissions.

• Ensure documentation clearly states "Zone I" or describes a fracture consistent with Zone I (e.g., involving the sacral ala).
• Confirm the fracture is closed and this is the patient's initial encounter for this specific injury.
• If the specific type of Zone I fracture is documented (e.g., transverse, vertical), a more specific code should be used.
