Meeting your Insurance Company’s Definition of Medical Necessity for Minimally Invasive Sacroiliac (SI) Joint Fusion

Patient Education

Many health insurance plans have established patient selection guidelines for minimally invasive SI joint fusion. Like all procedures, your medical records must justify why a minimally invasive SI joint fusion procedure is the right procedure for you.

Some health plans have their own internal patient selection guidelines. Other plans follow guidelines published by professional medical societies and other technology assessment organizations, including guidelines by North American Spine Society (NASS), International Society of Advancement of Spine Surgery (ISASS), and AIM Specialty Health (AIM).

Below are commonly referenced patient criteria for minimally invasive SI joint fusion (check with your plan for specific procedure guidelines):

  • Have undergone and failed a minimum six months of conservative care, including medications, activity modification, bracing, and physical therapy targeted at your lumbar spine, pelvis, SI joint and hip, including a home exercise program.
  • Typically, unilateral pain that is below your lumbar spine (L5 vertebrae), localized over your posterior SI joint, and consistent with your SI joint pain.
  • A thorough physical exam demonstrating: localized tenderness with palpation over your sacral sulcus (Fortin Finger, see image) in the absence of tenderness of similar severity elsewhere and other obvious sources for pain do not exist.
  • Absence of generalized pain behavior (e.g., somatoform disorder) or generalized pain disorders (e.g., fibromyalgia).
  • Positive response to a cluster of 3 provocative tests (Distraction, Thigh Thrust, FABER Compression test, Gaenslen’s test).
  • Imaging to rule out other conditions, such as x-rays, CT scan, or MRI of your lumbar spine, hip and pelvis.
  • Short-term pain relief during the anesthetic phase of your intra-articular diagnostic SI joint injection.
  • At least one therapeutic SI  joint injection(corticosteroid injection).
