Draft justification
At this rural site, MRI is not available within a clinically acceptable window. Per resource-adjusted appropriateness, CT lumbar + targeted ultrasound is proposed as the highest-yield local pathway consistent with guideline-aligned conservative management, with documented follow-up if symptoms persist.
Estimated net (demo): $1,137,120 after denial rate and rural adj.
