Sprain of sacrotuberous (ligament)

This code signifies an injury to the sacrotuberous ligament, a strong fibrous band connecting the sacrum to the ischial tuberosity. This sprain involves stretching or tearing of the ligament fibers, often resulting from trauma or sudden movements.

Use this code when documentation clearly indicates a sprain or strain specifically affecting the sacrotuberous ligament. This typically occurs following falls, direct impact to the gluteal region, or hyperextension injuries. The diagnosis should be supported by physician notes detailing the mechanism of injury, pain localization, and physical examination findings.

• Ensure the documentation specifies "sacrotuberous ligament" to avoid miscoding general pelvic or sacral sprains.
• Distinguish from sacral fractures (805.x) or sacroiliac joint sprains (846.1) which involve different anatomical structures.
• Consider an E-code to describe the external cause of the injury, if applicable.
