Severely displaced Zone I fx sacrum, init for opn fx

This code signifies a severe break in the sacrum, specifically in Zone I (the ala and sacral promontory), where the bone fragments are significantly out of alignment. It indicates that the fracture has broken through the skin, creating an open wound, and this is the first time the patient is receiving treatment for this injury.

Apply this code for patients presenting with a traumatic injury to the sacrum that has resulted in a visibly open wound and imaging confirms a severely displaced fracture involving the sacral ala or promontory. This code is appropriate for the initial hospital admission or outpatient encounter where definitive treatment for the open fracture is initiated.

• Ensure documentation clearly specifies "severely displaced" and "open fracture" to support code assignment.
• Verify the fracture location is explicitly documented as "Zone I" or involving the sacral ala/promontory.
• Confirm this is the patient's initial encounter for this specific injury; subsequent care would require a different encounter character.
