Purpose/Objective(s): Delivering Stereotactic Body Radiation Therapy (SBRT) requires the integration of several time-sensitive steps. In some disease states, delay to treatment has been found to impact clinical outcome. Obtaining insurance authorization is a critical initial task to mitigate against patient financial hardship. Despite this, there is a paucity of literature identifying predictors of protracted insurance authorization for patients who receive robotic-based SBRT. This study explores factors that influence time from simulation order to insurance authorization at a busy hospital practice.
Materials/Methods: We conducted a retrospective review of simulation order requests for patients undergoing robotic-based SBRT during the year 2017. We queried data fields that included insurance type, treatment site, and fractionation request. Insurance categories included Medicare, Medicaid, Commercial, and Self-Pay. These fields were cross referenced with time stamps of the simulation order and insurance authorization date.
Results: From January 4, 2017 to December 29, 2017, 583 consecutive simulations were ordered for robotic-based SBRT. Patient insurance included Medicare (36.7%); Medicaid (0.1%) Commercial (60.9%); and (2.1%) patients self-paid. The most common treatment sites were prostate (60.9%), lung (10.1%), and brain (10.1%). Mean time to insurance authorization was 10 days (0-105). 13.4% of cases took >20 days for insurance authorization and 7.5% of cases took >30 days. Commercial insurance carrier predicted for longer mean authorization time compared to Medicare or Medicaid insurance (13.5d vs. 4.1d and 4.0d, p<.0001). Insurance approval for robotic-SBRT was considerably shorter for cases involving brain, lung, and spine sites than for prostate (3.8d, 3.4d, 4.0d vs. 12.0d, p<.0001). Single fraction cases were approved more expeditiously than cases involving 2-5 or >5 fraction sizes (3.8d vs. 10.2d and 16.8d, p=.03). Predictors of time >5days for authorization included Commercial vs. Medicare insurance (56.3% vs. 13.1%, p<.0001), prostate vs. lung and brain cases (45.1% vs. 18.6% and 27.1%, p<.0001), and 5 fraction vs. 1 fraction cases (66.7% vs. 20.7%, p=.005). On multivariate analysis, predictors of longer insurance authorization included non-Medicare insurance (OR 10.2, CI 2.7-40.0, p=.001) and treatment with ≥5 fractions (OR 3.8, CI 1.2-11.9, p=.02).
Conclusion: Most patients attain insurance authorization for robotic-based SBRT within 2 weeks’ time from simulation order. Factors contributing to delay to insurance authorization include non-Medicare carriers as well as ≥5 fraction size. Further study is warranted to prospectively assess whether incorporating this information into dynamic workflow can improve clinical efficiency.
