Medical-necessity criteria Liberty Mutual generally applies
Decision point review (DPR) required: CT is on the N.J.A.C. 11:3-4.5(b) diagnostic-test list, so the determination to administer it is a decision point for ALL injuries, not just Care Path injuries (11:3-4.5(d)). No DPR or precertification applies to emergency care or within 10 days of the accident (11:3-4.7(b)) - medical necessity and causation still apply. Submit the DOBI Uniform APTP form with clinically supported findings from a personal examination; the carrier must respond within 3 business days (11:3-4.7(c)4), and under DOBI-approved plans treatment is deemed authorized until a determination issues if it fails to respond timely. Failure to request DPR where required risks a co-payment penalty of up to 50% of the eligible charge (11:3-4.4(e)); using a non-network facility where the plan has an approved voluntary network for CT can add a penalty of up to 30% (11:3-4.4(g), 11:3-4.8(b)).
