Summary
BCBS MS updated their sacroiliac joint pain policy, establishing strict medical necessity criteria for minimally invasive SI joint fixation/fusion procedures and limiting diagnostic injections to two per calendar year. The policy specifies approved titanium triangular implant systems and requires extensive documentation including specific pain levels, failed conservative treatment, and positive diagnostic tests.
Action Required
Immediately: Billing team must update prior authorization processes for sacroiliac joint procedures to verify all criteria are met before scheduling. Update encounter forms to include pain scale documentation (minimum 5/10), conservative treatment history (minimum 6 months), and required diagnostic test results. Providers must document 75% pain reduction from diagnostic injections and limit SI joint injections to maximum 2 per calendar year. Claims will be denied if extensive medical necessity criteria are not met.
