Fatigue fracture of vertebra, lumbosacral region, sqla

This code signifies a stress fracture of a vertebra in the lower back or sacrum that occurred due to repetitive stress rather than a single traumatic event. It specifically indicates that the fracture is a long-term complication or residual effect of a previously healed or resolved fracture in the same region.

Apply this code when documentation clearly states a fatigue or stress fracture of a lumbar or sacral vertebra, and explicitly links it as a sequela of an earlier, distinct fracture. This would be used for patients presenting with chronic pain or instability related to the prior fracture site, now manifesting as a new stress fracture.

• Ensure documentation specifies "fatigue fracture" or "stress fracture" and explicitly links it as a "sequela" of a prior fracture.
• Do not use for acute traumatic vertebral fractures or for nonunion/malunion of a current fracture.
• Always sequence this code after the primary condition or injury that led to the sequela, if applicable and still active.
