Abstract Purpose A common denial trend that occurs with “outpatient medical benefit drugs” (ie, medications covered by a medical benefit plan and administered in an outpatient visit) is payers not requiring or permitting prior authorization (PA) proactively, yet denying the drug after administration for medical necessity. In this situation, a preemptive strategy of complying with payer-mandated requirements is critical for revenue protection. To address this need, our institution incorporated a medical necessity review into its existing closed-loop, pharmacy-managed precertification and denials management program. Summary Referrals for targeted payers and high-cost medical benefit drugs not eligible for PA and deemed high risk for denial were incorporated into the review. Payer medical policies were evaluated and clinical documentation assessed to confirm alignment. This descriptive report outlines the medical necessity workflow as a component of the larger precertification process, details the decision-making process when performing the review, and delineates the roles and responsibilities for involved team members. A total of 526 drug orders were evaluated from September 2018 to August 2019, with 146 interventions completed. Of the 761 individual claims affected by proactive medical necessity review, 99.2% resulted in payment and less than 1% resulted in revenue loss, safeguarding more than $5.3 million in annual institutional drug reimbursement. At the time of analysis, there were only 3 cases of revenue loss. Conclusion Our institution’s pharmacy-managed medical necessity review program for high-cost outpatient drugs safeguards reimbursement for therapies not eligible for payer PA. It is a revenue cycle best practice that can be replicated at other institutions.
