Disorder of ligament, right ankle

This code signifies a non-traumatic derangement or dysfunction of the ligaments supporting the right ankle joint. This can include conditions like chronic ligamentous laxity, degeneration, or other acquired disorders not resulting from an acute injury. It excludes acute sprains or tears.

Use this code when documentation specifies a non-traumatic disorder of the ligaments of the right ankle, such as chronic instability or degenerative changes. Supporting documentation should clearly indicate the right ankle and differentiate the condition from an acute sprain or tear.

• Ensure the documentation specifies "right ankle" and "ligament disorder" to avoid laterality or anatomical site errors.
• Distinguish carefully between acute ligamentous injuries (e.g., sprains, tears) and chronic or degenerative disorders.
• Do not use for acute sprains; refer to the S93.4- category for those conditions.
