Sprain of sacroiliac ligament

This code signifies an injury to the ligaments stabilizing the sacroiliac joint, typically resulting from a sudden twisting motion, fall, or direct trauma. It involves the stretching or tearing of these fibrous tissues connecting the sacrum and ilium, leading to localized pain and dysfunction.

Apply this code when documentation clearly indicates a sprain or strain of the sacroiliac ligament. This is often diagnosed based on physical examination findings, such as tenderness over the SI joint, positive provocative tests, and a history consistent with ligamentous injury.

• Differentiate from sacroiliac joint dysfunction (720.2) or low back pain (724.x) when the primary pathology is ligamentous injury.
• Ensure documentation specifies "sprain" or "strain" of the sacroiliac ligament, not just general sacroiliac pain.
• Consider an external cause code (E-code) if the injury resulted from an accident or trauma.
