Nondisplaced Zone III fracture of sacrum, sequela

This code describes a healed or residual effect of a fracture located in Zone III of the sacrum, which involves the sacral ala and sacroiliac joint, that was nondisplaced at the time of injury. It indicates that the acute phase of the fracture has passed, and the patient is now experiencing a long-term complication or condition resulting from the original injury.

Use this code when documenting a follow-up encounter for a patient who previously sustained a nondisplaced Zone III sacral fracture and is now presenting with a sequela, such as chronic pain, nonunion, malunion, or nerve impingement directly attributable to the old fracture. This code is appropriate for encounters occurring after the initial healing period of the acute fracture.

• Always assign an additional code to specify the nature of the sequela (e.g., chronic pain, nonunion).
• Do not use this code for initial or subsequent encounters for an active, healing fracture; those require codes from the initial or subsequent encounter categories.
• Ensure documentation clearly links the current condition to the previously sustained nondisplaced Zone III sacral fracture.
