Summary
Humana Oklahoma Medicaid updated its policy for chronic pain injections (epidural steroid injections, facet joint injections, sacroiliac joint injections, trigger point injections, and peripheral nerve blocks) effective July 29, 2026. The policy establishes specific coverage criteria including mandatory 4-week conservative treatment, radicular pain confirmation, imaging guidance requirements, and strict frequency/level limitations for procedures. Billing teams must ensure prior authorization compliance and proper documentation of conservative treatment attempts before claim submission.
Action Required
Before July 29, 2026: Billing team must update prior authorization workflows in billing system to require documentation of 4 consecutive weeks of conservative treatment (activity modification, medications, physical therapy) before approving codes 62321, 62323, and 64483. Implement system checks to enforce: (1) maximum 1 nerve root level per session for caudal/interlaminar approaches, (2) maximum 2 injections per session for transforaminal/SNRB (unilateral or bilateral single level), (3) minimum 2-week intervals during diagnostic phase (max 2 injections), (4) minimum 2-month intervals during therapeutic phase, and (5) requirement that real-time imaging guidance (CT/fluoroscopy) be documented as integral to procedure. Providers must confirm radicular pain with positive straight leg raise or dermatomal sensory loss. Update encounter templates to require documentation of these criteria. Billing team must deny claims lacking required prior authorization and supporting documentation. Train billing and provider staff on new frequency limitations and level restrictions to prevent over-coding and claim denials.
