Purpose:
Prior authorization (PA) can be a resource-intensive barrier to oncologic care. To improve patient access and reduce delays at our large, academic proton therapy center, we implemented a novel payor-focused strategy to efficiently navigate the PA process while eliminating physician burden and reducing inappropriate denials.
Methods:
In 2017, business operations were redesigned to better reflect the insurance process: (1) certified medical dosimetrists (CMDs), with their unique treatment expertise, replaced our historical PA team to function as an effective interface among physicians, patients, and payors; (2) a structured, tiered timeline was implemented to hold payors accountable to PA deadlines; and (3) our PA team provided administrative leadership with requisite insurance knowledge. PA outcomes were compared 6 months before and after the intervention.
Results:
After implementation of this multifaceted strategy, the median time to successful appeal (after initial denial of coverage) decreased from 30 to 18 days (P < .001), and the total number of overturned denials increased by 56%. Because of the efficiency of the CMDs, full-time equivalents on the PA team actually decreased by 44%, translating to a 34% reduction in team personnel expenses. Internal referrals increased by 29%, attributable to optimized communication and diminished administrative burden for providers. New treatment starts also increased, resulting in a 37% larger patient census on treatment.
Conclusion:
Incorporating payor-focused strategies can improve patient access in a cost-effective manner while decreasing time and administrative burden associated with the PA process. These operational concepts can be adapted for other oncologic practice settings facing analogous PA-related obstacles.
