Sacroiliitis, not elsewhere classified

This code signifies inflammation of the sacroiliac joint, which connects the sacrum to the ilium. It represents sacroiliitis that is not specifically categorized under other infectious, traumatic, or systemic inflammatory conditions.

Use this code when documentation indicates sacroiliac joint inflammation without a more specific underlying cause identified. It is appropriate for idiopathic sacroiliitis or when the etiology is unknown or not otherwise classifiable.

• Ensure documentation explicitly states "sacroiliitis" and does not specify a more definitive cause (e.g., infectious, psoriatic, traumatic).
• Avoid using this code if a more specific ICD-9-CM code for sacroiliitis (e.g., related to ankylosing spondylitis or Crohn's disease) is available and supported by documentation.
• Review the patient's medical history for systemic inflammatory conditions that might provide a more specific diagnosis for the sacroiliitis.
